Class JSONObject

java.lang.Object
java.util.AbstractMap<K,​V>
java.util.HashMap
org.drip.service.representation.JSONObject
All Implemented Interfaces:
java.io.Serializable, java.lang.Cloneable, java.util.Map, JSONAware, JSONStreamAware
public class JSONObject
extends java.util.HashMap
implements java.util.Map, JSONAware, JSONStreamAware
JSONObject is an Adaptation of the JSONObject Class from the RFC4627 compliant JSON Simple (https://code.google.com/p/json-simple/). It provides the following Functionality:
  • Escape quotes, \, /, \r, \n, \b, \f, \t and other control characters (U+0000 through U+001F). It's the same as JSONValue.escape() only for compatibility here
  • Encode a map into JSON text and write it to out. If this map is also a JSONAware or JSONStreamAware, JSONAware, or JSONStreamAware specific behavior will be ignored at this top level
  • Convert a map to JSON text. The result is a JSON object. If this map is also a JSONAware, JSONAware specific behavior will be omitted at this top level
  • Encode "this" map into JSON text and write it to out. If this map is also a JSONAware or JSONStreamAware, JSONAware, or JSONStreamAware specific behavior will be ignored at this top level
  • Convert "this" map to JSON text. The result is a JSON object. If this map is also a JSONAware, JSONAware specific behavior will be omitted at this top level
  • Convert "this" to JSON text - this directly defers to JSON'izer

  • Constructor Details

    • JSONObject

      public JSONObject()
      Empty JSONObject Constructor JSONize the key-value String Empty JSONObject Constructor Allows creation of a JSONObject from a Map. After that, both the generated JSONObject and the Map can be modified independently. Encode "this" map into JSON text and write it to out. If this map is also a JSONAware or JSONStreamAware, JSONAware, or JSONStreamAware specific behavior will be ignored at this top level.

    • JSONObject

      public JSONObject​(java.util.Map map)
      Allows creation of a JSONObject from a Map. After that, both the generated JSONObject and the Map can be modified independently.
      Parameters:
      map - Input JSON Map
