Hypodermic

Hypodermic is a non-intrusive header only IoC container for C++. It provides dependency injection to your existing design by managing the creation of your components and their dependencies in the right order, sparing you the trouble of writing and maintaining boiler plate code.

Used in production environments since 2012.

First steps

Configure the container by registering your components

ContainerBuilder builder;

builder.registerType< MessageDispatcher >();

auto container = builder.build();

... then ask the container to give you an instance of that type

auto dispatcher = container->resolve< MessageDispatcher >();

Benchmarks

Some comparative benchmarks are available on the wiki, check them out.

Acknowledgment

Hypodermic was started with the will to mimic the famous .NET Autofac http://autofac.org/. Although its design evolved, both its behavior and its expressiveness tend to remain the same.

Constructor deduction has been made possible thanks to the work of Krzysztof Jusiak in http://boost-experimental.github.io/di/.

hypodermic's Issues

Bug: interface is resolved twice from nested container if they are added as both .as<interface>() and .asSelf()

Hi! Thanks for creating this awesome library, it has saved me so much time and headaches!

I took a fast screenshot from debugger to show my problem:

So what is happening here is that I have container and then I'm supposed to reload the plugins at runtime when they are rebuilt (I simplified the code in screenshot to show the issue). Somehow all the systems are resolved twice when I resolve them from application container. I was able to narrow this down in having my systems registered as<core::system>() and .asSelf(). If I remove asSelf() the system is resolved only once from nested container container.

I'm not sure if this is just my setup or wider issue. I´m running
macOS with AppleClang 12.0.5
Boost 1.75 from vcpkg

Type dependencies

Hello there,
Thanks for the very cool project.

Question 1:
I've been using the version you've published in the past, using the INJECT macro in order to declare dependencies of a type.

So for example:

builder.registerType< Car>(CREATE(new Car(INJECT(IDriver))))->as< ICar>()->singleInstance();

in this example, i need to be familiar only with the IDriver interface.

I see that you changed this implementation and now the above should look something like this:

builder.registerType< Car>().with< IDriver, Driver >().as< ICar>().singleInstance();

right?
But now it seems like i need to be familiar with both IDriver and Driver

Am i missing something?

Question 2:
Does the new version compiles faster comparing to the previous release?

Thanks alot,
Amit

resolve with constructor Parameter

Hi,

is there a Way to call resolve with constructor Parameters, like
container->resolve< IServiceA >(5,"Hello World!");

Resolve other than shared_ptr (e.g. unique_ptr)

At least for types which are not registered as single instance, i.e. a new instance is returned for every call to resolve(), is there a chance to resolve as something other than shared_ptr, and, specifically, with unique_ptr?
Maybe it's possible to add a method named "resolveUnique" for this? And it would throw if the type cannot be resolved for a unique instance -- whether it's not registered, or registered as single instance.
I am asking this because the use of shared_ptr is often too heavy for what I really need.

Fail to build in window boost1.7 gcc9

In include Hypodermic.h to my own code and build, it shows error when build in window boost1.7 gcc9.

[FeatureRequest] Fluent lifetime management

Hi,

As far as I am concerned there are only 3 ways to manage the dependency lifetime. We could either specifically say there should be a single instance:

builder.registerType< MessageDispatcher >()
       .as< IMessageDispatcher >()
       .singleInstance();

or we could use single instance for child container living as long as long child container exist. The last way is default behaviour which I believe is one instance per resolve.

In our application we are concerned about very strong multi-threading. In such scenarios we might want:

• One instance per thread
• Multiple instances per thread
• One instance across multiple threads

So the proposal is to add another syntax like:

builder.registerType< MessageDispatcher >()
       .as< IMessageDispatcher >()
       .withLifetimeManager(InstancePerThreadLifetimeManager());

InstancePerThreadLifetimeManager is an implementation of LifetimeManagerObject exposing the following methods:

• resolveDependency
• removeDependency

LifetimeManager has to have access to getOrCreateComponent method so it can make Hypodermic create new instances.

with std::thread::get_id we would be able to implement LifetimeManager so it distributes instances of requested object so there is always exactly one instance per thread. Such implementation injection allows us to fully customize the objects lifetime which is crucial for multi-threading project.

Thanks,
Patryk

test case "container_should_be_injectable_as_well" fails on windows and mingw

in fact this might be a simple type_info issue see #8

type_info == type_info not equal for same types across DLLs on windows

this is making resolve completly unusable if you build your container within a DLL and want to resolve types within an EXE

I've encountered this issue myself and it was quite hard to find where the issue was.

Показан перевод для запроса Не компилирует с абстрактными классами и Искать вместо этого перевод для Не компилируеться с абстрактными классами и It does not compile with abstract classes and boos 1.6

I try to create a container for such a simple hierarchy.

include "Hypodermic/ContainerBuilder.h"

include "Hypodermic/Container.h"

class A
{
public:

    virtual void method1()abstract;

};

class B:public A
{
public:
void method1() override
{
}
};

int main()
{
Hypodermic::ContainerBuilder builder;
builder.registerType().asSelf().as().singleInstance();
auto container = builder.build();
container->resolve()->method1();
return 0;
}

Use VS 2015 and boost 1.6. Got error message error C2259: 'A': cannot instantiate abstract class

does not build with clang and <=boost-1.53

It is required to use hypodermic with at least boost-1.54. This should be a boost signals2 bug within boost itself.

I don't think its a major issue, but its nice to know it.

Question: register two interfaces for same concrete class

Suppose Foo implements ISome and IThing. How does one register both interfaces, while ensuring that there is only a single Foo instance?

I can achieve it by using a factory method for one of the interfaces, and some dynamic_cast wizardry. Would be nice if Hypodermic allowed chaining as<...>() to register multiple interfaces.

pkg-config: 'libdir' not defined

Hello.

The generated pkgconfig/libhypodermic.pc doesn't work because libdir is not set.
I'm not sure, but maybe the "Libs: .. -lboost_system" line isn't even necessary and can be deleted.

$ pkg-config --cflags libhypodermic
Variable 'libdir' not defined in '/usr/local/lib/pkgconfig/libhypodermic.pc'

Kind regards, Paul

Is there a version without boost

I really like the DI style of C# autofac, and it would be great if they could be used in C++.

But I hope there's no need to introduce overly large libraries (such as boost)

Is it possible to specify the dependency explicitly while resolving

Hi

I have the following classes:

class IDatabaseConnection;

class RepositoryA : public IRepositoryA {
  RepositoryA(std::shared_ptr<IDatabaseConnection>);
};

class RepositoryB : public IRepositoryB {
  RepositoryB(std::shared_ptr<IDatabaseConnection>);
};

In some cases, I want the same IDatabaseConnection to be shared when constructing RepositoryA and RepositoryB:

auto db = container->resolve<IDatabaseConnection>();
db->startTransaction();

auto repoA = container->resolve<IRepositoryA>(); // here I want to pass db explicitly to the constructor
auto repoB = container->resolve<IRepositoryB>(); // here I want to use db explicitly to the constructor

db->commit();

Note that in other cases, sharing the db instance is not necessary or desired (which is the default behaviour of Hypodermic)

Is it possible to achieve this behaviour? and if so, could you please provide an example?

Thanks

ContainerBuilder doesn't have a virtual destructor

Hello,
In this section of the beginner guide, it's suggesting to inherit from the ContainerBuilder class.

However we have noticed that ContainerBuilder class doesn't have a virtual destructor.
Is that a bug? Inheriting from that class may cause undefined behaviour

@ybainier - can you please clarify that? Thanks.

could you provide a tutorial for how to compile build and use it?

could you provide a tutorial for how to compile build and use it?

I cannot build it with visual studio 2005, v140

Support for C++17

Any plans to support C++17? It currently fails on removed std::unary_function http://www.cplusplus.com/reference/functional/unary_function/

No release/tags

There is no tags in this repository which makes hard to know what is considered stable or not.
@ybainier, can you include some tags/releases?

Issue when resolving same types in different shared libraries

Hi!

I've had long running issue in my project in which, when I try to resolve a type in functions from different shared libraries (dylib, I'm running macOS) I have had different results. Steps to repro are:

• I have executable, library that is dynamically linked and then one that I hot reload
• In my linked library I have builder which creates a container.
• In my hot-reloadable library I have builder which I use to register types for nested container
• After new types have been created I'm resolving some systems

Issue is that If in my hot-reloadable library try to resolve from my container I get completely new instance for all singletons. It is as if comparing of types is not working -- and it isn't. I was looking and TypeAlias, TypeKeyKey and TypeInfo and they use std::type_info. After fast googling it would seem that operating with type_info and type_index are undefined behaviour between different DLLs, so they are not comparable. As it is UB this might not be an issue in all OSs or compilers. I have tested this with this changeset and it fixes my issue as the name of the class is of course same in my whole application. I'm not sure yet of side-effects this might have, but it works great for me.

I then asked ChatGPT if it knows the answer to this and it provided me with following answer (I have no idea if this is correct or not, its ChatGPT):

It is generally not safe to compare typeid of a class in different shared libraries. 
The typeid operator returns a type_info object that provides information about the type of an object. 
This information is implementation-defined, and may be different between different compilers, libraries, or even different versions of the same library.
If you need to compare the types of objects from different shared libraries, you should provide a unique identifier for each type that is guaranteed to be consistent across all libraries. 
This can be achieved by using a unique identifier for each type, such as a string or an integer, and comparing the identifier instead of the typeid.
In C++17 and later, you can use the std::type_index class to compare types across shared libraries. 
The std::type_index class stores a type_info object and provides a hash function that allows you to compare types in a consistent manner across different libraries.

So maybe storing type_index in TypeInfo is the real answer? I'm really not sure. I know my use-case might be a bit niche but it would be great if something similar would be implemented upstream.

EDIT: I did try just storing type_index but it had the original effech: not working

Autowiring of factory methods

In order to achieve full dependency inversion, I don't want to expose the concrete classes from code modules, but rather factory methods creating concrete objects implementing a given interface. They look like this:

struct IFoo { ... };
struct IBar { ... };

struct FooFactory
{
    static std::unique_ptr<IFoo> createInstance(std::shared_ptr<IBar>);
    FooFactory() = delete;
};

Unfortunately, registering the factory is very verbose:

builder.registerInstanceFactory([=](Hypodermic::ComponentContext& context) 
    -> std::shared_ptr<IFoo> {
        return FooFactory::createInstance(context.resolve<IBar>());
        });

(1) Would it be possible to provide auto-wiring for factory methods, just as for constructors, something likes this:

builder.registerInstanceFactory(FooFactory::createInstance).as<IFoo>();

NOTE: the factories return std::unique_ptr not std::shared_ptr because they are IoC (Hypodermic) agnostic. Converting from the former to the later is trivial. But still, Hypodermic currently requires one to force that conversion (-> std::shared_ptr<IFoo>). Would be nice if that was implicit.

How to inject a factory for named instances?

https://github.com/ybainier/Hypodermic/wiki/Expressing-dependencies#injecting-an-instance-factory gives an example of injecting a function that can be used as a factory. However, this seems to only work with anonymously-registered types. It seems there's no way to get a factory function that I could pass a name to, to get a named implementation back, is that right? I tried requesting a function that takes a const &string, but that didn't compile. How hard would it be to add that feature?

License not listed

The google code page used to list an MIT license. I'm interested in using this code. Could you add a license to this repo?

Alternatives to `std::make_shared`

Would it be possible to add the ability to create instances with something other than std::make_shared. Some of our objects require a custom deleter and it seems that we cannot inject the deleter when registering types.

Is there a way to accomplish this now by inheriting from a container builder?

Checking for not null.

Hi!

I would like to get an error either at compile time or at runtime if a specific type is required, but was not registered. Is it possible?

Resolution by name using TBase as T itself

The named binder requires that a TBase parameter is passed to it. However, this makes impossible to create a named reference to objects without a base class, due to its EnforceBaseOf implementation.

struct MyClass {};
Hypodermic::ContainerBuilder builder;
builder.registerType<MyClass>.named<MyClass>(); // fails with TBase should be a base of T

By changing EnforceBaseOf static_assert to

static_assert(std::is_base_of< TBase, T >::value, "TBase should be T itself or a base of T");

the code compiles and run fine, but this does not seem like a clean solution to this problem.

Is there any specific reason why you have explicitly excluded non-polymorphic classes from the named resolution? If you think this solution is good enough, I can provide a pull request with the given changes and some test cases.

how to register a constructor that takes an argument

Resolution of single instances based on concrete and abstract types

Greetings, I'm using this container and am really quite happy with it. However, there is one quirk that I've found myself working around and I wonder if it's something that you would consider changing or if it's even possible.

I have some code that does the following:

Hypodermic::ContainerBuilder builder;

builder.registerType<ConcreteClass>().as<InterfaceClass>().singleInstance();
...
auto container = builder.build();
...
auto singleton_interface_ref = container->resolve<InterfaceClass>();
auto singleton_concrete_ref = container->resolve<ConcreteClass>();

assert(singleton_interface_ref == singleton_concrete_ref); // Fails!

auto singleton_concrete_ref2 = container->resolve<ConcreteClass>();
assert(singleton_concrete_ref == singleton_concrete_ref2); // Passes

auto singleton_interface_ref2 = container->resolve<InterfaceClass>();
assert(singleton_interface_ref == singleton_interface_ref2); // Passes

Is it possible to have Hypodermic resolve the same reference regardless of whether you resolve the type ConcreteClass or InterfaceClass? My actual use-case is more layered than this, but I thought I'd start out with an illustrative example to see if it was even possible.

Thanks!

use make_shared instead of new calls

well, maybe this is resolved already, but I just moved all my issues I had left in the old repository

Resolve a chain of instantiate of explicit dependencies name?

Hi,

Whether or not Hypodermic will dynamically resolve a specific instantiates with explicit dependency name?

For example :

class IMessageSerializer{...};
class class LengthPrefixedMessageSerializer_1 : public IMessageSerializer {...};
class class LengthPrefixedMessageSerializer_2 : public IMessageSerializer {...};
class class LengthPrefixedMessageSerializer_3 : public IMessageSerializer {...};

class IMessageWriter{};

class ConsoleMessageWriter : public IMessageWriter
{
public:
explicit ConsoleMessageWriter(std::shared_ptr< IMessageSerializer > serializer)
: m_serializer(serializer)
{
}
...
};

builder.registerType< LengthPrefixedMessageSerializer_1 >().as< IMessageSerializer >().named("N1");

builder.registerType< LengthPrefixedMessageSerializer_2 >().as< IMessageSerializer >().named("N2");

builder.registerType< LengthPrefixedMessageSerializer_3 >().as< IMessageSerializer >().named("N3");;

builder.registerType< ConsoleMessageWriter >().as< IMessageWriter >();

std::shared_ptr< Hypodermic::Container > m_container;

m_container = builder.build();

auto messageWriter = m_container->resolve< IMessageWriter >();

While I resolve the IMessageWriter, base on tutor page "Fallback registrations" it will always return a type by using its last registration. There IMessageWriter was resolved an instance with LengthPrefixedMessageSerializer_3.

How to dynamically assign a specific instance with an explicit dependency name to IMessageWriter with LengthPrefixedMessageSerializer_1 ~ 3 ?

Thank you.

Neil

============================================
I read all tutor page, I found a "with" method help me bondle LengthPrefixedMessageSerializer_1 ~ 3 like this example :

builder.registerType< ConsoleMessageWriter >().
with<IMessageSerializer , LengthPrefixedMessageSerializer_1 >()
.as< IMessageWriter >();

So, I resolved IMessageWriter which is returned ConsoleMessageWriter with LengthPrefixedMessageSerializer_1.

But..., It's not good for me. If I need LengthPrefixedMessageSerializer_1 ~ 3, I will create IMessageWriter_1 ~ 3 for mapping...

So, whether or not has a method will help me decode those name interface dynamically.

Thank you very much.

Neil

Hi,

I trace the stackoverflow for this situation, I should change the injection method to "Method Injection".
So, rewrite code as below :

builder.registerType< LengthPrefixedMessageSerializer_1 >().named< IMessageSerializer >("N1");

builder.registerType< LengthPrefixedMessageSerializer_2 >().named< IMessageSerializer >("N2");

builder.registerType< LengthPrefixedMessageSerializer_3 >().named< IMessageSerializer >("N3");

ConsoleMessageWriter : public IMessageWriter
{
public:
explicit ConsoleMessageWriter()
{
}
void SetMessageSerializer (std::shared_ptr< IMessageSerializer > serializer)
{
m_serializer = serializer;
}

...

};

And then,

auto messageWriter = m_container->resolve<IMessageWriter>();	
auto serializer = m_container->resolveNamed<IMessageSerializer>("N2");

	messageWriter->SetMessageSerializer (serializer);

I think it is a good idea for this situation.

Neil

Using .with<T>(instance)

I'm trying to set up a call to .with() when registering a type with an existing instance of an object, following the sample on the Hypodermic github site, as shown below. The .with() executes without incident, but it does not wire up the dependency in the parent object, which is left empty. According to the docs, it seems this should work. Is there something I'm doing wrong?

class IFoo
{
public:
virtual void Bar() = 0;
};

class Foo : public IFoo
{
public:
virtual void Bar() override {};
};

class IBaz { };

class Baz : public IBaz
{
public:
Baz(std::shared_ptr foo) : m_pFoo(foo) {};
std::shared_ptr m_pFoo;
};

Hypodermic::ContainerBuilder builder;
auto foo = std::make_shared();
builder.registerType() .with(foo) .as();
builder.build();

auto pBaz = pContainer->resolve();

Visual Studio 2017 does not build lib

I have clone the repository. open solution right click on the Hypodermic project and select build option.

1>------ Rebuild All started: Project: Hypodermic, Configuration: Debug x64 ------
========== Rebuild All: 1 succeeded, 0 failed, 0 skipped ==========

that is all what I got and there is no Hypodermic.lib in output folder.

Please help.

Bug: singleInstance not working as expected when resolving from nested containers

I have a problem when resolving service that is meant to be used as singleInstance from nested containers. I have written a test case here:

#include <cassert>

#include <Hypodermic/ContainerBuilder.h>

struct interface
{
    virtual bool& get_value() = 0;
};

struct service : interface
{
    bool& get_value() final { return value; }

    bool value{};
};

int main(int args, const char** argv)
{
    auto builder = std::make_shared<Hypodermic::ContainerBuilder>();

    /// CASE1: this works if I resolve from container instead of nested container
    // using resolved_type = service;
    // builder->registerType<service>().singleInstance();

    /// CASE2: this works if I resolve from container instead of nested container
    // using resolved_type = interface;
    // builder->registerType<service>().as<interface>().singleInstance();

    /// CASE3: this works for both nested container and container
    // using resolved_type = interface;
    // builder->registerInstance(std::make_shared<service>()).as<interface>();

    /// CASE4: this works for both nested container and container
    using resolved_type = service;
    builder->registerInstance(std::make_shared<service>());

    auto container = builder->build();

    {
        auto nested_builder = std::make_shared<Hypodermic::ContainerBuilder>();
        auto nested_container = nested_builder->buildNestedContainerFrom(*container);
        auto service0 = nested_container->resolve<resolved_type>();
        service0->get_value() = true;
    }

    {
        auto nested_builder = std::make_shared<Hypodermic::ContainerBuilder>();
        auto nested_container = nested_builder->buildNestedContainerFrom(*container);
        auto service0 = nested_container->resolve<resolved_type>();
        assert(service0->get_value());
    }

    {
        auto service0 = container->resolve<resolved_type>();
        assert(service0->get_value());
    }

    return 0;
}

All of these cases work fine when I resolve the resolved_type from container instead of nested_container. However when resolving from nested_container cases 1 and 2 fail both of the asserts.

Pass parameters to register type

Hi,

I have function which gets 2 params (primitive types: string and char*), and need to do register type to a class where the ctor needs those 2 params.

I found other old issue (from 2015) which answers a very similar issue #13 but i'm getting exception for using it:
error: ‘IComponentContext’ has not been declared
=
^~~~~~~~~~~~~~~~~
When trying to change IComponentContext to ComponentContext i'm getting:
error: static assertion failed: Could not autowire T: you should consider registering T either by providing an instance or an instance factory

So what is the right syntax?
Thanks!

Incorrect activation hooks call order

Scenario:

1. Specify activation hook while registering class A
2. Register class B depending on class A
3. Perform resolve for class B

Code example:

#include <iostream>
#include <Hypodermic/ContainerBuilder.h>
#include <Hypodermic/Container.h>

class A
{
public:
    A() { std::cout << "Create A" << std::endl; }
};

class B
{
public:
    B(const std::shared_ptr<A>&) { std::cout << "Create B" << std::endl; }
};

int main()
{
    Hypodermic::ContainerBuilder builder;
    builder.registerType<A>()
           .singleInstance()
           .onActivated([](auto&, const std::shared_ptr<A>&){
        std::cout << "Activation Hook" << std::endl;
    });
    builder.registerType<B>();

    auto container = builder.build();
    auto b = container->resolve<B>();

    return 0;
}

Expected behavior:

Create A
Activation Hook
Create B

Current behavior:

Create A

Hypodermic 2.5.3 won't link with Boost

A while back I installed your library so that I could look at the code that David Sackstein presented in his CppCon 2022 presentation 10 Tips for Cleaner C++ code.

I've been trying to get his code running under VS2022 Preview which currently fails, and so I've revisited it, as part of demonstrating to MS that the preview has now broken the code from the presentation.

I tried upgrading both of the third party libraries tl::expected and Hypodermic.

However when it came to trying to build version 2.5.3 I find it doesn't link properly, unfortunately I threw away my previous copy of your library and so I don't know what version I was working from. I looked for old .zip files and it looks like I must previously have just cloned the repository at the time, and so now I can't go back.

When I encountered the errors in VS2022, I tried again to build Hypodermic in VS2019 but the same errors occur.

Current syntax for register factory with arguments

hi,
Currently i'm using a very old Hypodermic version with the following syntax:
builder.registerType< FooFactory >(CREATE(std::make_shared< FooFactory >(
INJECT(IClass1),
INJECT(IClass2)
))).as< IFooFactory >().singleInstance();
where IClass1 and IClass2 are the params to FooFactory ctor.

I'm not sure how to convert it to the current syntax (without CREATE and INJECT).
I tried builder.registerInstanceFactory and builder.registerInstance and it didn't work.
I also tried to pass the params with context.resolve / container->resolve and it didn't work.

so what should i do? thanks!
