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> r, 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

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

Description copied from interface: RegionMembershipListener

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.

Specified by:

initialMembers in interface RegionMembershipListener<K,V>

Parameters:

r - 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

public void afterRemoteRegionCreate(RegionEvent<K,V> event)

Description copied from interface: RegionMembershipListener

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

Specified by:

afterRemoteRegionCreate in interface RegionMembershipListener<K,V>

Parameters:

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

afterRemoteRegionDeparture

public void afterRemoteRegionDeparture(RegionEvent<K,V> event)

Description copied from interface: RegionMembershipListener

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.

Specified by:

afterRemoteRegionDeparture in interface RegionMembershipListener<K,V>

Parameters:

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

afterRemoteRegionCrash

public void afterRemoteRegionCrash(RegionEvent<K,V> event)

Description copied from interface: RegionMembershipListener

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.

Specified by:

afterRemoteRegionCrash in interface RegionMembershipListener<K,V>

Parameters:

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