/**
|
||
|
|
* JSON is an open standard file format, and data interchange format,
|
||
|
|
* that uses human-readable text to store and transmit data objects
|
||
|
|
* consisting of name–value pairs and array data types.
|
||
|
|
* For more information refer to https://en.wikipedia.org/wiki/JSON
|
||
|
|
* This is a base class for implementation of JSON data storage for Acedia.
|
||
|
|
* It does not implement parsing and printing from/into human-readable
|
||
|
|
* text representation, just provides means to store such information.
|
||
|
|
*
|
||
|
|
* JSON data is stored as an object (represented via `JSONObject`) that
|
||
|
|
* contains a set of name-value pairs, where value can be
|
||
|
|
* a number, string, boolean value, another object or
|
||
|
|
* an array (represented by `JSONArray`).
