public static final InterestPolicy ALL
When combined with DataPolicy.EMPTY
this region will receive
events for every distributed operation but will not store the data.
When combined with DataPolicy.NORMAL
or
DataPolicy.PRELOADED
this region will accept
Region.create(Object, Object)
operations done remotely. Without
the ALL
interest policy, NORMAL
and
PRELOADED
ignore creates
that the region
does not have an existing entry for.
When combined with the replication
policies
this interest has no effect.
When combined with DataPolicy.PARTITION
this interest policy
causes cache listeners to be notified of changes regardless of the
physical location of the data affected. That is, a listener in a VM
using this policy will receive notification of all changes to the
partitioned region.
public static final InterestPolicy CACHE_CONTENT
When combined with DataPolicy.EMPTY
this region will never
receive events for distributed operations since its content is always
empty. It will continue to get events for operations done locally.
When combined with DataPolicy.NORMAL
or
DataPolicy.PRELOADED
this region will accept remote operations
done to entries it already has in its cache.
When combined with the replication
policies
* this interest has no effect.
When combined with DataPolicy.PARTITION
this interest policy
causes cache listeners to be notified in the VM holding the affected data.
That is, listeners are only notified if the affected* key-value pair is
in the same process as the listener.
