Hi!
Very cool feature I must say!
I'm trying to achieve something but I can seem to make it work.
This is my example:
@GenericEnum
public enum Test implements ActionFactory<@GenericEnumParam Object> {
FEATURE_FLAGS(AActionClass.class, a -> new AActionClass()),
NOT_FEATURE_FLAGS(BActionClass.class, b -> new BActionClass());
Test(Class<? extends ActionClass> actionClass, ActionFactory<@GenericEnumParam Object> constructor) {
this.constructor = constructor;
}
private final ActionFactory<@GenericEnumParam Object> constructor;
@Override
public @GenericEnumParam Object getAction(String s) {
return constructor.getAction(s);
}
}
This is the ActionFactory class:
interface ActionFactory<T> {
T getAction(String input);
}
public class ActionClass {
public void method() {
System.out.println("method");
}
}
public class AActionClass extends ActionClass {
public void a() {
System.out.println("A");
}
}
public class BActionClass extends ActionClass {
public void b() {
System.out.println("A");
}
}
After compile it creates TextExt with some errors:
public static final TestExt<AActionClass> FEATURE_FLAGS=new TestExt<AActionClass>(AActionClass.class, (a)->new AActionClass(), "FEATURE_FLAGS", 0);
public static final TestExt<BActionClass> NOT_FEATURE_FLAGS=new TestExt<BActionClass>(BActionClass.class, (b)->new BActionClass(), "NOT_FEATURE_FLAGS", 1);
private final String __enum_name__;
private final int __ordinal__;
private final ActionFactory<@GenericEnumParam() Object> constructor;
private TestExt(Class<? extends ActionClass> actionClass, ActionFactory<@GenericEnumParam() Object> constructor, String __enum_name__, int __ordinal__) {
this.constructor = constructor;
this.__enum_name__=__enum_name__;
this.__ordinal__=__ordinal__;
}
public T getAction(String s) {
return constructor.getAction(s);
}
The constructor variable is ActionFactory<@GenericEnumParam() Object>
instead of ActionFactory<T>
private TestExt(Class<? extends ActionClass> actionClass, ActionFactory<@GenericEnumParam() Object>
Am I missing anything ? is this something I can achieve with current implementation or it's a new feature need to develop ?
Thanks!!
Hi Christophe,
While working on another PR I've noticed that some files include "Copyright Google LLC". I suspect this is a copy'n'paste error as they are all pom.xml files. They also mention the Apache license.
I'd just like to clarify that this project falls under the MIT license.
You can see the affected files here: https://github.com/cmoine/generic-enums/search?q=copyright
Cheers,

Hi Christophe,
Great project. Would it be possible to add support for enums inside classes?
For example:
class MyOuterClass {
public enum InnerEnum implements MyInterface<T> {
ONE(String.class),
TWO(Date.class);
...
}
}
I have a branch with this working, it needs some tidying up which I should be able to do early next week. If I do that would you consider merging it?
Cheers,
Simon
