Threadsafe collections for Objective C.
A collection of classes which encapsulate NSMutableArray, NSMutableDictionary, and NSMutableSet for threadsafe concurrent read and write access. Inspired by a post by Mike Ash.
- More comprehensive tests.
- Additional collection types.
If you're using CocoPods it's as simple as adding this to your
Podfile:
pod 'GRKConcurrentCollections'
otherwise, simply add the contents of the GRKConcurrentCollections subdirectory to your
project.
To use, simply import the header for the collection you want to use:
#import "GRKConcurrentMutableArray.h"
#import "GRKConcurrentMutableDictionary.h"
#import "GRKConcurrentMutableSet.h"
Then you can use instances of the same to perform read and write operations to the instances from multiple threads without being concerned about collisions.
Please note that when modifying the contents of the collections from multiple threads, the
actual contents will be unpredictable due to thread scheduling. One should consider using
the "Snapshot" methods to get the contents at any one particular time, or the
augmentWithBlock: method to perform a sequence of operations on the collection without
being concerned about concurrency.
Additional documentation is available in each header file.
