Method Summary

void	addSubscriptionProfile(Profile profile) This method adds a subscription profile to the matching tree
int	getManagedProfileType() Returns the type of profiles managed by this matching engine
int	getMatchingLevel() This method returns the level assocaited with this matching tree.
Object	matchEvent(NBEvent nbEvent)
void	propagateChangesToHigherLevels(Profile profile, boolean addProfile) Propagates profile changes to higher levels
void	removeSubscriptionProfile(Profile profile) This method adds a subscription profile to the matching tree
void	setNodeDestination(Destinations destination) This method sets the destination address for this node

Method Detail

getMatchingLevel

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

void setNodeDestination(Destinations destination)

This method sets the destination address for this node

addSubscriptionProfile

void addSubscriptionProfile(Profile profile)

This method adds a subscription profile to the matching tree

Parameters:

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

removeSubscriptionProfile

void removeSubscriptionProfile(Profile profile)

This method adds a subscription profile to the matching tree

propagateChangesToHigherLevels

void propagateChangesToHigherLevels(Profile profile,
                                    boolean addProfile)

Propagates profile changes to higher levels

matchEvent

Object matchEvent(NBEvent nbEvent)

getManagedProfileType

int getManagedProfileType()

Returns the type of profiles managed by this matching engine
