Method Detail

createEvent

public static <K,V> EventImpl<K,V> createEvent(Cache<K,V> cache,
                               Event.Type type)

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 occurred, false if after the event has occurred.

getCache

public Cache<K,V> getCache()

Specified by:

getCache in interface Event

Returns:

a handle to the cache instance that generated this notification.

getKey

public K getKey()

Specified by:

getKey in interface CacheEntryEvent

Returns:

the key to the affected cache entry.

getGlobalTransaction

public GlobalTransaction getGlobalTransaction()

Specified by:

getGlobalTransaction 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.

isTransactionSuccessful

public boolean isTransactionSuccessful()

Specified by:

isTransactionSuccessful in interface TransactionCompletedEvent

Returns:

if true, the transaction completed by committing successfully. If false, the transaction completed with a rollback.

setPre

public void setPre(boolean pre)

setKey
