Method Detail

getPriority

public int getPriority()

Method which should return the priority level of this message. The messages can range in priority from 0 (highest priority) to Integer.MAX_VALUE (lowest) - when sending messages across the wire, the queue is sorted by message priority. If the queue reaches its limit, the lowest priority messages are discarded. Thus, applications which are very verbose should have LOW_PRIORITY or lower, and applications which are somewhat quiet are allowed to have MEDIUM_PRIORITY or possibly even HIGH_PRIORITY.

Specified by:

getPriority in interface Message

Returns:

This message's priority

getSource

public NodeHandle getSource()

Method which returns this messages' source address

Returns:

The source of this message

serialize

public void serialize(OutputBuffer buf)
               throws java.io.IOException

Specified by:

serialize in interface RawSerializable

Throws:

java.io.IOException
