Method Detail

size

int size()

Specified by:

size in interface Map<K,V>

atomicSize

int atomicSize()

Returns the current size of the TransactionalMap. The big difference between the normal size() method is that this one returns the actual size of this map and doesn't look at the current transaction. So you could see changes made by other threads.

Returns:

the current size of the TransactionalMap.
