EventImpl
public EventImpl()
getType
public Event.Type getType()
- Specified by:
getType
in interface Event
- Returns:
- the type of event represented by this instance.
isPre
public boolean isPre()
- Specified by:
isPre
in interface Event
- Returns:
- true if the notification is before the event has occured, false if after the event has occured.
getCache
public Cache getCache()
- Specified by:
getCache
in interface Event
- Returns:
- a handle to the cache instance that generated this notification.
getModificationType
public NodeModifiedEvent.ModificationType getModificationType()
- Specified by:
getModificationType
in interface NodeModifiedEvent
- Returns:
- an instance of the
NodeModifiedEvent.ModificationType
enumeration.
getData
public Map getData()
- Description copied from interface:
NodeModifiedEvent
- When called with isPre() == true, this is the initial state of the
Node
before modification.
When called with isPre() == false, this depends on the value of getModificationType():
Implementations interested in seeing the difference in the node data in the NodeModifiedEvent.ModificationType.PUT_MAP
case
can cache the value of getData() map passed when isPre() == true, and then when the
isPre() == false callback is received, pass the cached map and the new result of getData() to
Util.diffNodeData(java.util.Map,java.util.Map)
- Specified by:
getData
in interface NodeActivatedEvent
- Specified by:
getData
in interface NodeLoadedEvent
- Specified by:
getData
in interface NodeModifiedEvent
- Specified by:
getData
in interface NodePassivatedEvent
- Specified by:
getData
in interface NodeRemovedEvent
- Returns:
- an unmodifiable
Map
of data being activated. Empty map when Event.isPre()
returns true.
getFqn
public Fqn getFqn()
- Specified by:
getFqn
in interface NodeEvent
- Returns:
- the Fqn pointing to the node that is affected.
getTransaction
public Transaction getTransaction()
- Specified by:
getTransaction
in interface TransactionalEvent
- Returns:
- the Transaction associated with the current call. May be null if the current call is outside the
scope of a transaction.
isOriginLocal
public boolean isOriginLocal()
- Specified by:
isOriginLocal
in interface TransactionalEvent
- Returns:
- true if the call originated on the local cache instance; false if originated from a remote one.
getTargetFqn
public Fqn getTargetFqn()
- Specified by:
getTargetFqn
in interface NodeMovedEvent
- Returns:
- the new, resultant Fqn after the move
isSuccessful
public boolean isSuccessful()
- Specified by:
isSuccessful
in interface TransactionCompletedEvent
- Returns:
- if true, the transaction completed by committing successfully. If false, the transaction
completed with a rollback.
getNewView
public org.jgroups.View getNewView()
- Specified by:
getNewView
in interface ViewChangedEvent
- Returns:
- the new view associated with this view change.
