getUserData

public byte[] getUserData()

Returns the user data associated with this communication. User data can be up to 16 bytes and can contain any type of binary data. The user data is totally untouched by EntireX Broker. It is never transmitted from one application to another (i.e., from a client to a server). Both sides of a conversation can store different user data, and both sides always receive their own data.
The user data is transmitted on a send() method and returned with the message to the receiving application. User data can be overwritten with each send() call.

Returns:

user data as byte array or null.
