/* * * * *
|
|
* This is an extension of the SimpleJSON framework to provide methods to
|
|
* serialize a JSON object tree into a compact binary format. Optionally the
|
|
* binary stream can be compressed with the SharpZipLib when using the define
|
|
* "USE_SharpZipLib"
|
|
*
|
|
* Those methods where originally part of the framework but since it's rarely
|
|
* used I've extracted this part into this seperate module file.
|
|
*
|
|
* You can use the define "SimpleJSON_ExcludeBinary" to selectively disable
|
|
* this extension without the need to remove the file from the project.
|
|
*
|
|
* If you want to use compression when saving to file / stream / B64 you have to include
|
|
* SharpZipLib ( http://www.icsharpcode.net/opensource/sharpziplib/ ) in your project and
|
|
* define "USE_SharpZipLib" at the top of the file
