|
|
* 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
|
|
*
|
|
* [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<string, JSONNode>, 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<string, JSONNode> 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.
