cgl.narada.matching.hierarchical
Class ClientHierarchicalMatching

java.lang.Object
  extended by cgl.narada.matching.hierarchical.ClientHierarchicalMatching
All Implemented Interfaces:
HierarchicalDebugFlags, MatchingTree

public class ClientHierarchicalMatching
extends Object
implements MatchingTree, HierarchicalDebugFlags

This class implements the Hierarchical 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

ClientHierarchicalMatching

public ClientHierarchicalMatching(int unitLevel,
                                  int systemLevel,
                                  ProfilePropagationProtocol profilePropagationProtocol)
The HierarchicalMatching 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.

Specified by:
getMatchingLevel in interface MatchingTree
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 MatchingTree

addSubscriptionProfile

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

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

removeSubscriptionProfile

public void removeSubscriptionProfile(Profile profile)
Description copied from interface: MatchingTree
This method adds a subscription profile to the matching tree

Specified by:
removeSubscriptionProfile in interface MatchingTree

removeProfilesForDestination

public void removeProfilesForDestination(Object clientIdentifier,
                                         String linkId)

removeProfileWithId

public void removeProfileWithId(Object profileId)
This method removes a subscription profile


propagateChangesToHigherLevels

public void propagateChangesToHigherLevels(Profile profile,
                                           boolean addProfile)
Description copied from interface: MatchingTree
Propagates profile changes to higher levels

Specified by:
propagateChangesToHigherLevels in interface MatchingTree

matchEvent

public Object matchEvent(NBEvent nbEvent)
This method return the destinations assocaited with an event that needs to be matched to the matching tree

Specified by:
matchEvent in interface MatchingTree
Returns:
The destination as an INT

getManagedProfileType

public int getManagedProfileType()
Returns the type of profiles managed by this matching engine

Specified by:
getManagedProfileType in interface MatchingTree
