Interface InvalidationBridgeListener

All Known Implementing Classes:
JMSCacheInvalidationBridge

public interface InvalidationBridgeListener

InvalidationManager (IM) represents locally managed caches and invaliders. To be able to do distributed invalidations, it is necessary to bridge these IM to forward cache invalidation messages. The InvalidationBridgeListener provides the way for any transport mechanism to be used to forward cache invalidation messages accross a network/cluster.

Method Detail

batchInvalidate

void batchInvalidate(BatchInvalidation[] invalidations,
                     boolean asynchronous)
Called when a set of invalidations, concerning more than one IG, should be forwarded accross the bridge. It is the bridge responsability to determine: - which IG must be bridged (some IG may not exist on other nodes, in this case the bridge may decide to drop these invalidations messages to reduce the serialization cost and network usage) - to which other nodes the invalidations must be communicated. This can be done by any mean (automatic discovery, configuration file, etc.)

Parameters:
invalidations - BatchInvalidation messages containing invalidations
asynchronous - Determine the best-effort indication to be used to communicate invalidations

invalidate

void invalidate(String invalidationGroupName,
                Serializable key,
                boolean asynchronous)
Called when a single invalidation, concerning a single IG, should be forwarded accross the bridge. It is the bridge responsability to determine: - which IG must be bridged (some IG may not exist on other nodes, in this case the bridge may decide to drop these invalidations messages to reduce the serialization cost and network usage) - to which other nodes the invalidations must be communicated. This can be done by any mean (automatic discovery, configuration file, etc.)

Parameters:
invalidationGroupName - InvalidationGroup name
key - Key to be invalidated
asynchronous - Best effort communication setting

invalidate

void invalidate(String invalidationGroupName,
                Serializable[] keys,
                boolean asynchronous)
Called when a set of invalidations, concerning a single IG, should be forwarded accross the bridge. It is the bridge responsability to determine: - which IG must be bridged (some IG may not exist on other nodes, in this case the bridge may decide to drop these invalidations messages to reduce the serialization cost and network usage) - to which other nodes the invalidations must be communicated. This can be done by any mean (automatic discovery, configuration file, etc.)

Parameters:
invalidationGroupName - Name of the InvalidationGroup to which is linked the invalidation message
keys - Keys to be invalidated
asynchronous - Best effort communication setting

invalidateAll

void invalidateAll(String groupName,
                   boolean asynchronous)
Issues invalidate all event to other nodes.

Parameters:
groupName - group's name
asynchronous - mode

groupIsDropped

void groupIsDropped(String groupInvalidationName)
Called when an InvocationGroup is dropped (because no cache and invalider are using it anymore). For bridge implementations that automatically discover which IG should be bridged, this callback can be used to communicate to the other nodes that this node is no more interested in invalidation for this group.

Parameters:
groupInvalidationName - Name of the InvalidationGroup being dropped

newGroupCreated

void newGroupCreated(String groupInvalidationName)
Called when an InvocationGroup is created. For bridge implementations that automatically discover which IG should be bridged, this callback can be used to communicate to the other nodes that this node is now interested in invalidation for this group.

Parameters:
groupInvalidationName - Name of the InvalidationGroup just being created
