- The bulk of the UTF8 / UTF32 conversion and verification comes
- from ConvertUTF.[hc]. It has been modified from the original sources.
-
- The original sources were obtained from http://www.unicode.org/.
- However, the web site no longer seems to host the files. Instead,
- the Unicode FAQ http://www.unicode.org/faq//utf_bom.html#gen4
- points to International Components for Unicode (ICU)
- http://site.icu-project.org/ as an example of how to write a UTF
- converter.
-
- The decision to use the ConvertUTF.[ch] code was made to leverage
- "proven" code. Hopefully the local modifications are bug free.
-
- The code in isValidCodePoint() is derived from the ICU code in
- utf.h for the macros U_IS_UNICODE_NONCHAR and U_IS_UNICODE_CHAR.

-// JSONKit v1.4 used both a JKArray : NSArray and JKMutableArray : NSMutableArray, and the same for the dictionary collection type.
-// However, Louis Gerbarg (via cocoa-dev) pointed out that Cocoa / Core Foundation actually implements only a single class that inherits from the
-// mutable version, and keeps an ivar bit for whether or not that instance is mutable. This means that the immutable versions of the collection
-// classes receive the mutating methods, but this is handled by having those methods throw an exception when the ivar bit is set to immutable.
-// We adopt the same strategy here. It's both cleaner and gets rid of the method swizzling hackery used in JSONKit v1.4.

- The NSString and NSData convenience methods need a little bit of explanation.
-
- Prior to JSONKit v1.4, the NSString -objectFromJSONStringWithParseOptions:error: method looked like
-
- const unsigned char *utf8String = (const unsigned char *)[self UTF8String];
- if(utf8String == NULL) { return(NULL); }
- size_t utf8Length = strlen((const char *)utf8String);
- return([[JSONDecoder decoderWithParseOptions:parseOptionFlags] parseUTF8String:utf8String length:utf8Length error:error]);
-
- This changed with v1.4 to a more complicated method. 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. The downside is having a an object or two in
- autorelease limbo, but we've done our best to minimize that impact, so it all balances out.

- // In fact, the C standard says that the hack below is "undefined behavior"- there is no requirement that the 10.7 tagged pointer hack of setting the
- // "lower, unused bits" must be preserved when casting the result to an integer type, but this "works" because for most architectures
- // `sizeof(long) == sizeof(void *)` and the compiler uses the same representation for both. (note: this is informal, not meant to be
- // normative or pedantically correct).
- //
- // In other words, while this "works" for now, technically the compiler is not obligated to do "what we want", and a later version of the compiler
- // is not required in any way to produce the same results or behavior that earlier versions of the compiler did for the statement below.
- //
- // Fan-fucking-tastic.
- //
- // Why not just use `object_getClass()`? Because `object->isa` reduces to (typically) a *single* instruction. Calling `object_getClass()` requires
- // that the compiler potentially spill registers, establish a function call frame / environment, and finally execute a "jump subroutine" instruction.
- // Then, the called subroutine must spend half a dozen instructions in its prolog, however many instructions doing whatever it does, then half a dozen
- // instructions in its prolog. One instruction compared to dozens, maybe a hundred instructions.
- //
- // Yes, that's one to two orders of magnitude difference. Which is compelling in its own right. When going for performance, you're often happy with
- // gains in the two to three percent range.
