Method Detail

jsonStringToToken

public static Token jsonStringToToken(String aJsonString)

Convert a json string to a token. If the json string isn't a valid one, return an empty token. Note that if you need a more generic conversion (other sub protocol than json), you may also use the following: Token lToken = TokenServer.packetToToken(aConnector, new RawPacket(aJsonString)) Depending of the SubProtocol of aConnector, the token will be automatically created (if the SubProtocol is WS_SUBPROT_JSON, the conversion will be done internally using this method)

Parameters:

aJsonString - a json string

Returns:

the token corresponding to the json string, or an empty token

packetToToken

public static Token packetToToken(WebSocketPacket aDataPacket)

converts a JSON formatted data packet into a token.

Parameters:

aDataPacket -

Returns:

tokenToPacket

public static WebSocketPacket tokenToPacket(Token aToken)

listToJsonArray

public static org.json.JSONArray listToJsonArray(List aList)
                                          throws org.json.JSONException

transform a list to a JSONArray

Parameters:

aList -

a JSONArray which represents aList

Throws:

org.json.JSONException

objectListToJsonArray

public static org.json.JSONArray objectListToJsonArray(Object[] aObjectList)
                                                throws org.json.JSONException

transform a list of objects to a JSONArray

Parameters:

aObjectList -

Returns:

a JSONArray which represents aObjectList

Throws:

org.json.JSONException

mapToJsonObject

public static org.json.JSONObject mapToJsonObject(Map<?,?> aMap)
                                           throws org.json.JSONException

                                       throws org.json.JSONException
