Richard: I'm unsure about three of these, which were fixes in memset() calls in: - NSConcreteMapTable.m - NSConcreteHashTable.m - Additions/NSData+GNUstepBase.m Please can you check them? I think they are intended to zero the entire object (rather than the first word), but the lack of comments makes me unsure. Most changes were just tweaks to variable types. I've also removed some dead code from NSInvocation. This was small group of things that were marked for internal use only, but not actually referenced in the code anywhere. Other improvements: - NSArray / NSDictionary fixed up to use the 10.7 (ARC-friendly) prototypes. - getObjects:andKeys: implemented for NSDictionary (10.5 method) - NSPointerArray and NSHashTable now properly support weak objects. - Tests for weak objects in collections. git-svn-id: svn+ssh://svn.gna.org/svn/gnustep/libs/base/trunk@33621 72102866-910b-0410-8b05-ffd578937521

/**
|
|
* <p>NSAssertionHandler objects are used to raise exceptions on behalf of
|
|
* macros implementing assertions.<br />
|
|
* Each thread has its own assertion handler instance.<br />
|
|
* </p>
|
|
* <p>The macros work together with the assertion handler object to
|
|
* produce meaningful exception messages containing the name of the
|
|
* source file, the position within that file, and the name of the
|
|
* ObjC method or C function in which the assertion failed.
|
|
* </p>
|
|
* <p>An NSAssertionHandler instance is created on demand for each thread
|
|
* and is stored in the thread's dictionary under the key NSAssertionHandler.
|
|
* A custom NSAssertionHandler can be used by adding it to the thread
|
|
* dictionary under this key.
|
|
* </p>
|
|
* The assertion macros are:
|
|
* NSAssert(), NSCAssert(),
|
|
* NSAssert1(), NSCAssert1(),
|
|
* NSAssert2(), NSCAssert2(),
|
|
* NSAssert3(), NSCAssert3(),
|
|
* NSAssert4(), NSCAssert4(),
|
|
* NSAssert5(), NSCAssert5(),
|
|
* NSParameterAssert(), NSCParameterAssert()
