Constructor Detail

UnsubscribeMessage

public UnsubscribeMessage(NodeHandle source,
                          java.util.List<Topic> topics)
Constructor which takes a unique integer Id

Parameters:
id - The unique id
source - The source address
dest - The destination address
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

getTopics

public java.util.List<Topic> getTopics()
Method which returns this messages' topic

Returns:
The topic of this message
