Package org.apache.geode.cache

Interface RegionMembershipListener<K,V>

All Superinterfaces:

CacheCallback, CacheListener<K,V>, Declarable

All Known Implementing Classes:

RegionMembershipListenerAdapter, RegionRoleListenerAdapter

public interface RegionMembershipListener<K,V>
extends CacheListener<K,V>

A listener that can be implemented to handle region membership events.

Instead of implementing this interface it is recommended that you extend the RegionMembershipListenerAdapter class.

Since:

GemFire 5.0

Method Summary

Modifier and Type	Method	Description
void	afterRemoteRegionCrash(RegionEvent<K,V> event)	Invoked when another member's distributed region is no longer available to this cache because the member has crashed or is no longer reachable on the network.
void	afterRemoteRegionCreate(RegionEvent<K,V> event)	Invoked when another member has created the distributed region this listener is on.
void	afterRemoteRegionDeparture(RegionEvent<K,V> event)	Invoked when another member's distributed region is no longer available to this cache due to normal operations.
void	initialMembers(Region<K,V> region, DistributedMember[] initialMembers)	Invoked when the listener is first initialized and is given the set of members that have the region created at that time.

Method Details

initialMembers

void initialMembers(Region<K,V> region,
 DistributedMember[] initialMembers)

Invoked when the listener is first initialized and is given the set of members that have the region created at that time. The listener is initialized when:

• the region is created with an already added listener
• a listener is added using the AttributesMutator.

Parameters:

region - the Region the listener is registered on

initialMembers - an array of the other members that have this region at the time this listener is added.

afterRemoteRegionCreate

void afterRemoteRegionCreate(RegionEvent<K,V> event)

Invoked when another member has created the distributed region this listener is on.

Parameters:

event - the event from the member whose region was created.

afterRemoteRegionDeparture

void afterRemoteRegionDeparture(RegionEvent<K,V> event)

Invoked when another member's distributed region is no longer available to this cache due to normal operations. This can be triggered by one of the following methods:

• Region.localDestroyRegion()
• Region.close()
• RegionService.close()

This differs from afterRemoteRegionCrash notification in that the departed member performed an action either to remove its region or to close its region or cache.

Parameters:

event - the event from the member whose region is no longer available.

afterRemoteRegionCrash

void afterRemoteRegionCrash(RegionEvent<K,V> event)

Invoked when another member's distributed region is no longer available to this cache because the member has crashed or is no longer reachable on the network.

Parameters:

event - the event from the member whose region is no longer available.
