The reason for this is to keep the amount of memory that is + * allocated, but not yet freed because it is dependent on the autorelease pool to pop before it can be reclaimed. + * + * In the simpler v1.3 code, this included all the bytes used to store the -UTF8String along with the JSONDecoder and all its overhead. + * + * Now we use an autoreleased CFMutableData that is sized to the UTF8 length of the NSString in question and is used to hold the UTF8 + * conversion of said string. + * + * Once parsed, the CFMutableData has its length set to 0. This should, hopefully, allow the CFMutableData to realloc and/or free + * the buffer. + * + * Another change made was a slight modification to JSONDecoder so that most of the cleanup work that was done in -dealloc was moved + * to a private, internal function. These convenience routines keep the pointer to the autoreleased JSONDecoder and calls + * _JSONDecoderCleanup() to early release the decoders resources since we already know that particular decoder is not going to be used + * again. + * + * If everything goes smoothly, this will most likely result in perhaps a few hundred bytes that are allocated but waiting for the + * autorelease pool to pop. This is compared to the thousands and easily hundreds of thousands of bytes that would have been in + * autorelease limbo. It's more complicated for us, but a win for the user. + * + * Autorelease objects are used in case things don't go smoothly. By having them autoreleased, we effectively guarantee that our + * requirement to -release the object is always met, not matter what goes wrong.
