Returns the capacity of the pool, i.e.
Returns the capacity of the pool, i.e. the maximum number of objects the pool can hold.

Object "destructor".
Object "destructor". This method is called whenever the object is evicted from the pool. For example, when doing connection pooling it is necessary to close the connection whenever it is evicted (i.e. permanently removed) from the pool.
Factory method for creating new objects.
Factory method for creating new objects.
a new object.
An health check that is performed on an object before its leased from the pool.
An health check that is performed on an object before its leased from the pool. If the health check passes the object is successfully leased. Otherwise, the object is destroyed (and a new one is fetched or created)
Returns the number of live objects, i.e.
Returns the number of live objects, i.e. the number of currently pooled objects plus leased objects.
The value returned by this method is only accurate when the referenceType is
io.github.andrebeat.pool.ReferenceType.Strong, since GC-based eviction is checked only
when trying to acquire an object.
the number of live objects.
Returns the io.github.andrebeat.pool.ReferenceType of the objects stored in the pool.
Resets the internal state of object.
Resets the internal state of object. This method is called on an object whenever it is
added/released back to the pool. For example, if pooling an object like a
java.nio.ByteBuffer it might make sense to call its reset() method whenever the object
is released to the pool, so that its future users do not observe the internal state introduced
by previous ones.

Closes this pool, and properly disposes of each pooled object, releasing any resources associated with the pool (e.g. background timer threads).
If the pool has already been closed this method does nothing.
Drains the object pool, i.e.
Drains the object pool, i.e. evicts every object currently pooled.
ClosedPoolException If this pool is closed.
Fills the object pool by creating (and pooling) new objects until the number of live objects reaches the pool capacity.
