Constructor Detail

ApplicationMessage

public ApplicationMessage(byte[] data,
                  InetSocketAddress peerAddress)

Creates a new APPLICATION_DATA message containing specific data.

Parameters:

data - byte array with the application data.

peerAddress - the IP address and port the message is to be sent to or has been received from

Throws:

NullPointerException - if peer or data is null
