Method Detail

getKey

public K getKey()

getValue

public V getValue()

getValue

public V getValue(boolean keepBinary)

Returns the value stored in the cache when this entry was created.

Parameters:

keepBinary - Flag to keep binary if needed.

Returns:

the value corresponding to this entry

value

public V value()

Returns:

Return value. This methods doesn't initialize value.

key

public K key()

Returns:

Return key. This methods doesn't initialize key.

keepBinary

public boolean keepBinary()

Returns:

Keep binary flag.

getPartitionUpdateCounter

public long getPartitionUpdateCounter()

Each cache update increases partition counter. The same cache updates have on the same value of counter on primary and backup nodes. This value can be useful to communicate with external applications. The value has sense only for entries get by CacheInterceptor.onAfterPut(Cache.Entry) and CacheInterceptor.onAfterRemove(Cache.Entry) methods. For entries got by other methods will return 0.

Specified by:

getPartitionUpdateCounter in class CacheInterceptorEntry<K,V>

Returns:

Value of counter for this entry.

updateCounter

public void updateCounter(long updateCntr)

Sets update counter.

Parameters:

updateCntr - Update counter.

unwrap

public <T> T unwrap(Class<T> cls)

toString

public String toString()

Overrides:

toString in class Object
