Interface BinaryMessage

All Superinterfaces:

Message

public interface BinaryMessage

extends Message

An interface representing a binary message. This is a subinterface of Message which contains methods to get and set the binary data payload. The setPayloadData() method sets the value of the payload in the data container without any checking whether the value is valid in any way. Methods for manipulating the address portion of the message are inherited from Message.

Object instances implementing this interface are just containers for the data that is passed in.

Method Summary

byte[]	getPayloadData() Returns the message payload data as an array of bytes.
void	setPayloadData(byte[] data) Sets the payload data of this message.

Methods inherited from interface javax.wireless.messaging.Message

getAddress, getTimestamp, setAddress

Method Detail

getPayloadData

public byte[] getPayloadData()

Returns the message payload data as an array of bytes.

Returns null, if the payload for the message is not set.

The returned byte array is a reference to the byte array of this message and the same reference is returned for all calls to this method made before the next call to setPayloadData.

Returns:

the payload data of this message or null if the data has not been set

setPayloadData(byte[])

setPayloadData

public void setPayloadData(byte[] data)

Sets the payload data of this message. The payload may be set to null.

Setting the payload using this method only sets the reference to the byte array. Changes made to the contents of the byte array subsequently affect the contents of this BinaryMessage object. Therefore, applications should not reuse this byte array before the message is sent and the MessageConnection.send method returns.

Parameters:

data - payload data as a byte array
