cgl.narada.matching.jms
Class ClientJmsMatching

java.lang.Object
  cgl.narada.matching.jms.ClientJmsMatching

All Implemented Interfaces:

JmsMatchingDebugFlags, JmsMatchingTree

public class ClientJmsMatching
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

ClientJmsMatching

public ClientJmsMatching(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 jmsProfile)

This method adds a subscription profile to the matching tree

Specified by:

addSubscriptionProfile in interface JmsMatchingTree

Parameters:

jmsProfile - The profile comprising the subscription and the destination assocaited with the subscription.

removeSubscriptionProfile

public void removeSubscriptionProfile(JmsProfile jmsProfile)

Specified by:

removeSubscriptionProfile in interface JmsMatchingTree

removeProfilesForDestination

public void removeProfilesForDestination(Object clientIdentifier,
                                         String linkId)

removeProfileWithId

public void removeProfileWithId(Object profileId)

This method removes a subscription profile

propagateChangesToHigherLevels

public void propagateChangesToHigherLevels(JmsProfile jmsProfile,
                                           boolean addProfile)

Specified by:

propagateChangesToHigherLevels in interface JmsMatchingTree

matchEvent

public Hashtable 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)
