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 + * + * [2012-06-09 First Version] + * - 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. + * + * [2017-04-11 Update] + * - Fixed parsing bug where empty string values have been ignored. + * - Optimised "ToString" by using a StringBuilder internally. This should heavily improve performance for large files + * - Changed the overload of "ToString(string aIndent)" to "ToString(int aIndent)" + * + * [2017-11-29 Update] + * - Removed the IEnumerator implementations on JSONArray & JSONObject and replaced it with a common + * struct Enumerator in JSONNode that should avoid garbage generation. The enumerator always works + * on KeyValuePair, even for JSONArray. + * - Added two wrapper Enumerators that allows for easy key or value enumeration. A JSONNode now has + * a "Keys" and a "Values" enumerable property. Those are also struct enumerators / enumerables + * - A KeyValuePair can now be implicitly converted into a JSONNode. This allows + * a foreach loop over a JSONNode to directly access the values only. Since KeyValuePair as well as + * all the Enumerators are structs, no garbage is allocated. + * - To add Linq support another "LinqEnumerator" is available through the "Linq" property. This + * enumerator does implement the generic IEnumerable interface so most Linq extensions can be used + * on this enumerable object. This one does allocate memory as it's a wrapper class. + * - The Escape method now escapes all control characters (# < 32) in strings as uncode characters + * (\uXXXX) and if the static bool JSONNode.forceASCII is set to true it will also escape all + * characters # > 127. This might be useful if you require an ASCII output. Though keep in mind + * when your strings contain many non-ascii characters the strings become much longer (x6) and are + * no longer human readable. + * - The node types JSONObject and JSONArray now have an "Inline" boolean switch which will default to + * false. It can be used to serialize this element inline even you serialize with an indented format + * This is useful for arrays containing numbers so it doesn't place every number on a new line + * - Extracted the binary serialization code into a seperate extension file. All classes are now declared + * as "partial" so an extension file can even add a new virtual or abstract method / interface to + * JSONNode and override it in the concrete type classes. It's of course a hacky approach which is + * generally not recommended, but i wanted to keep everything tightly packed. + * - Added a static CreateOrGet method to the JSONNull class. Since this class is immutable it could + * be reused without major problems. If you have a lot null fields in your data it will help reduce + * the memory / garbage overhead. I also added a static setting (reuseSameInstance) to JSONNull + * (default is true) which will change the behaviour of "CreateOrGet". If you set this to false + * CreateOrGet will not reuse the cached instance but instead create a new JSONNull instance each time. + * I made the JSONNull constructor private so if you need to create an instance manually use + * JSONNull.CreateOrGet() + * + * [2018-01-09 Update] + * - Changed all double.TryParse and double.ToString uses to use the invariant culture to avoid problems + * on systems with a culture that uses a comma as decimal point. + * + * [2018-01-26 Update] + * - Added AsLong. Note that a JSONNumber is stored as double and can't represent all long values. However + * storing it as string would work. + * - Added static setting "JSONNode.longAsString" which controls the default type that is used by the + * LazyCreator when using AsLong + * + * [2018-04-25 Update] + * - Added support for parsing single values (JSONBool, JSONString, JSONNumber, JSONNull) as top level value. + * + * The MIT License (MIT) + * + * Copyright (c) 2012-2017 Markus Göbel (Bunny83) + * + * Permission is hereby granted, free of charge, to any person obtaining a copy + * of this software and associated documentation files (the "Software"), to deal + * in the Software without restriction, including without limitation the rights + * to use, copy, modify, merge, publish, distribute, sublicense, and/or sell + * copies of the Software, and to permit persons to whom the Software is + * furnished to do so, subject to the following conditions: + * + * The above copyright notice and this permission notice shall be included in all + * copies or substantial portions of the Software. + * + * THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, EXPRESS OR + * IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF MERCHANTABILITY, + * FITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT.
