/* * * * *
|
|
* A simple JSON Parser / builder
|
|
* ------------------------------
|
|
*
|
|
* It mainly has been written as a simple JSON parser. It can build a JSON string
|
|
* from the node-tree, or generate a node tree from any valid JSON string.
|
|
*
|
|
* 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
|
|
*
|
|
* Written by Bunny83
|
|
* 2012-06-09
|
|
*
|
|
*
|
|
* Features / attributes:
|
|
* - provides strongly typed node classes and lists / dictionaries
|
|
* - provides easy access to class members / array items / data values
|
|
* - the parser now properly identifies types. So generating JSON with this framework should work.
|
|
* - only double quotes (") are used for quoting strings.
|
|
* - provides "casting" properties to easily convert to / from those types:
|
|
* int / float / double / bool
|
|
* - provides a common interface for each node so no explicit casting is required.
|
|
* - the parser tries to avoid errors, but if malformed JSON is parsed the result is more or less undefined
|
|
* - It can serialize/deserialize a node tree into/from an experimental compact binary format. It might
|
|
* be handy if you want to store things in a file and don't want it to be easily modifiable
|
|
*
|
|
*
|
|
* 2012-12-17 Update:
|
|
* - Added internal JSONLazyCreator class which simplifies the construction of a JSON tree
|
|
* Now you can simple reference any item that doesn't exist yet and it will return a JSONLazyCreator
|
|
* The class determines the required type by it's further use, creates the type and removes itself.
|
|
* - Added binary serialization / deserialization.
|
|
* - Added support for BZip2 zipped binary format. Requires the SharpZipLib ( http://www.icsharpcode.net/opensource/sharpziplib/ )
|
|
* The usage of the SharpZipLib library can be disabled by removing or commenting out the USE_SharpZipLib define at the top
|
|
* - The serializer uses different types when it comes to store the values. Since my data values
|
|
* are all of type string, the serializer will "try" which format fits best. The order is: int, float, double, bool, string.
|
|
* It's not the most efficient way but for a moderate amount of data it should work on all platforms.
|
|
*
|
|
* 2017-03-08 Update:
|
|
* - Optimised parsing by using a StringBuilder for token. This prevents performance issues when large
|
|
* string data fields are contained in the json data.
|
|
* - Finally refactored the badly named JSONClass into JSONObject.
|
|
* - Replaced the old JSONData class by distict typed classes ( JSONString, JSONNumber, JSONBool, JSONNull ) this
|
|
* allows to propertly convert the node tree back to json without type information loss. The actual value
|
|
* parsing now happens at parsing time and not when you actually access one of the casting properties.
