Class RtpMatching

java.lang.Object
  cgl.narada.matching.rtp.RtpMatching

All Implemented Interfaces:

RtpMatchingDebugFlags, RtpMatchingTree

public class RtpMatching
extends Object
implements RtpMatchingTree, RtpMatchingDebugFlags

This class implements the RTP 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

RtpMatching

public RtpMatching(int unitLevel,
                   int systemLevel,
                   RtpProfilePropagation rtpPropagate)

The RtpMatching 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 RtpMatchingTree

addSubscriptionProfile

public void addSubscriptionProfile(RtpProfile profile)

This method adds a subscription predicate to the matching tree

Specified by:

addSubscriptionProfile in interface RtpMatchingTree

Parameters:

predicate - The predicate comprising the subscription and the destination assocaited with the subscription.

removeSubscriptionProfile

public void removeSubscriptionProfile(RtpProfile profile)

This method removes a subscription predicate to the matching tree

Specified by:

removeSubscriptionProfile in interface RtpMatchingTree

Parameters:

predicate - The predicate comprising the subscription and the destination assocaited with the subscription.

propagateChangesToHigherLevels

public void propagateChangesToHigherLevels(RtpProfile rtpProfile,
                                           boolean addProfile)

Specified by:

propagateChangesToHigherLevels in interface RtpMatchingTree

matchEvent

public int matchEvent(RtpEvent rtpEvent)

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)
