  public JSON()

Method Detail

• encode

  public static java.lang.String encode(com.google.gwt.core.client.JavaScriptObject object)

  Serialize an object as a JSON string.

  Automatically handles circular references - see circularReferenceMode.

  Note that using the String produced by this API with JSON.decode will not successfully preserve dates. Use JSONEncoder.setDateFormat "dateConstructor" to have dates round-trip properly.

  Because GWT does not support Java reflection, JSON encoding cannot discover the properties of an arbitrary Java POJO. The following objects are supported:

  • any primitive type (String, Date, Number, Boolean)
  • any Map or Collection in any level of nesting
  • DataClass (Record's superclass) and RecordList
  • any widget (see +link{JSONEncoder.serializeInstances})
  • JavaScriptObject
  • an Array containing any of the above

  Parameters:

  object - object to serialize

  Returns:

  object encoded as a JSON String

  public static java.lang.String encode(com.google.gwt.core.client.JavaScriptObject object,

  Parameters:

  object - object to serialize

  settings - optional settings for encoding

  Returns:

  object encoded as a JSON String

• decode

  public static com.google.gwt.core.client.JavaScriptObject decode(java.lang.String jsonString)

  De-serialize an object from JSON. Currently, this is simply a JavaScript eval() and should be used for trusted data only.

  Parameters:

  jsonString - JSON data to be de-serialized

  Returns:

  object derived from JSON String
