NSMutableArray Mac OS X 10.0

This class extends the API of NSArray to allow for mutable, ordered collections of objects. NSMutableArray provides five primitive methods, which form the basis for the rest of its methods: addObject:, insertObject:atIndex:, removeLastObject, removeObjectAtIndex:, and replaceObjectAtIndex:withObject:. When an object is added to an array, the array asserts some ownership over the object by sending it a retain message. Likewise, when an object is removed from an array, it is sent a release message by the array.

NSMutableArray is toll-free bridged with the Core Foundation type CFArray. As such, NSMutableArray objects can be used interchangeably with the CFArray pointer type, CFArrayRef.
