Method Details

enable

public boolean enable(E pooled,
 boolean acquire)

Description copied from interface: Pool.Entry

Enables this, previously reserved, Entry.

An entry returned from the Pool.reserve() method must be enabled with this method, once and only once, before it is usable by the pool.

The entry may be enabled and not acquired, in which case it is immediately available to be acquired, potentially by another thread; or it can be enabled and acquired atomically so that no other thread can acquire it, although the acquire may still fail if the pool has been terminated.

Specified by:

enable in interface Pool.Entry<E>

Parameters:

pooled - the pooled object for this Entry

acquire - whether this Entry should be atomically enabled and acquired

Returns:

whether this Entry was enabled
