A JSON object is a map of string-based keys onto a set of com.google.gwt.json.client.JSONValue objects. Constructor Summary public   JSONObject()      public   JSONObject(JavaScriptObject jsValue)      Creates a new JSONObject from the supplied JavaScript value. Method Summary public  boolean containsKey(String key)      Tests whether or not this JSONObject contains the specified key. public  JSONValue get(String key)      Gets the JSONValue associated with the specified key. public  JSONObject isObject()      Returns this, as this is a JSONObject. public  Set<String> keySet()      Returns keys for which this JSONObject has associations. public  JSONValue put(String key, JSONValue jsonValue)      Maps the specified key to the specified value in this JSONObject. public  int size()      Determines the number of keys on this object. native public  String toString()      Converts a JSONObject into a JSON representation that can be used to communicate with a JSON service. Constructor Detail JSONObject public JSONObject()(Code) JSONObject public JSONObject(JavaScriptObject jsValue)(Code) Creates a new JSONObject from the supplied JavaScript value. Method Detail containsKey public boolean containsKey(String key)(Code) Tests whether or not this JSONObject contains the specified key. We use Object.hasOwnProperty here to verify that a given key is specified on this object rather than a superclass (such as standard properties defined on Object). Parameters:   key - the key to search for true if the JSONObject contains the specified key get public JSONValue get(String key)(Code) Gets the JSONValue associated with the specified key. We use Object.hasOwnProperty here to verify that a given key is specified on this object rather than a superclass (such as standard properties defined on Object). Parameters:   key - the key to search for if found, the value associated with the specified key, ornull otherwise isObject public JSONObject isObject()(Code) Returns this, as this is a JSONObject. keySet public Set<String> keySet()(Code) Returns keys for which this JSONObject has associations. array of keys for which there is a value put public JSONValue put(String key, JSONValue jsonValue)(Code) Maps the specified key to the specified value in this JSONObject. If the specified key already has an associated value, it is overwritten. Parameters:   key - the key to associate with the specified value Parameters:   jsonValue - the value to associate with this key if one existed, the previous value associated with the key, ornull otherwise throws:   NullPointerException - if key is null size public int size()(Code) Determines the number of keys on this object. toString native public String toString()(Code) Converts a JSONObject into a JSON representation that can be used to communicate with a JSON service. a JSON string representation of this JSONObject instance Methods inherited from com.google.gwt.json.client.JSONValue public JSONArray isArray()(Code)(Java Doc) public JSONBoolean isBoolean()(Code)(Java Doc) public JSONNull isNull()(Code)(Java Doc) public JSONNumber isNumber()(Code)(Java Doc) public JSONObject isObject()(Code)(Java Doc) public JSONString isString()(Code)(Java Doc) abstract public String toString() throws JSONException(Code)(Java Doc) Methods inherited from java.lang.Object native protected Object clone() throws CloneNotSupportedException(Code)(Java Doc) public boolean equals(Object obj)(Code)(Java Doc) protected void finalize() throws Throwable(Code)(Java Doc) final native public Class getClass()(Code)(Java Doc) native public int hashCode()(Code)(Java Doc) final native public void notify()(Code)(Java Doc) final native public void notifyAll()(Code)(Java Doc) public String toString()(Code)(Java Doc) final native public void wait(long timeout) throws InterruptedException(Code)(Java Doc) final public void wait(long timeout, int nanos) throws InterruptedException(Code)(Java Doc) final public void wait() throws InterruptedException(Code)(Java Doc)
