cgl.narada.matching.jms
Class JmsMatching

java.lang.Object
  extended by cgl.narada.matching.jms.JmsMatching
All Implemented Interfaces:
JmsMatchingDebugFlags, JmsMatchingTree

public class JmsMatching
extends Object
implements JmsMatchingTree, JmsMatchingDebugFlags

This class implements the JMS matching algorithm. This provides methods to add a subscription and also to remove interest in a subscription predicate. The matching algorithm should also be able to compute destinations.

Constructor Detail

JmsMatching

public JmsMatching(int unitLevel,
                   int systemLevel,
                   JmsProfilePropagation jmsPropagate)
The JmsMatching constructor

Method Detail

getMatchingLevel

public int getMatchingLevel()
This method returns the level assocaited with this matching tree. A node could be a gateway at multiple levels. How it handles destinations at different levels, and propagates destinations at different levels is dicatated by the level of the matching tree which computes the destinations and initiates profile propagation changes.

Returns:
The level of the matching tree.

setNodeDestination

public void setNodeDestination(Destinations destination)
This method sets the destination address for this node

Specified by:
setNodeDestination in interface JmsMatchingTree

addSubscriptionProfile

public void addSubscriptionProfile(JmsProfile profile)
This method adds a subscription predicate to the matching tree

Specified by:
addSubscriptionProfile in interface JmsMatchingTree
Parameters:
profile - The predicate comprising the subscription and the destination assocaited with the subscription.

removeSubscriptionProfile

public void removeSubscriptionProfile(JmsProfile profile)
This method removes a subscription predicate to the matching tree

Specified by:
removeSubscriptionProfile in interface JmsMatchingTree
Parameters:
profile - The predicate comprising the subscription and the destination assocaited with the subscription.

propagateChangesToHigherLevels

public void propagateChangesToHigherLevels(JmsProfile jmsProfile,
                                           boolean addProfile)
Specified by:
propagateChangesToHigherLevels in interface JmsMatchingTree

matchEvent

public int matchEvent(JmsEvent jmsEvent)
This method return the destinations assocaited with an event that needs to be matched to the matching tree

Returns:
The destination as an INT

main

public static void main(String[] args)
