Constructor Detail

StackObjectPoolFactory

public StackObjectPoolFactory()

Deprecated. to be removed in pool 2.0 - use StackObjectPoolFactory(PoolableObjectFactory)

Create a new StackObjectPoolFactory.

See Also:

StackObjectPool.StackObjectPool()

StackObjectPoolFactory

public StackObjectPoolFactory(int maxIdle)

Deprecated. to be removed in pool 2.0 - use StackObjectPoolFactory(PoolableObjectFactory, int)

Create a new StackObjectPoolFactory.

Parameters:

maxIdle - cap on the number of "sleeping" instances in the pool.

See Also:

StackObjectPool.StackObjectPool(int)

StackObjectPoolFactory

public StackObjectPoolFactory(int maxIdle,
                              int initIdleCapacity)

Deprecated. to be removed in pool 2.0 - use StackObjectPoolFactory(PoolableObjectFactory, int, int)

Create a new StackObjectPoolFactory.

Parameters:

maxIdle - cap on the number of "sleeping" instances in the pool.

initIdleCapacity - - initial size of the pool (this specifies the size of the container, it does not cause the pool to be pre-populated.)

See Also:

StackObjectPool.StackObjectPool(int, int)

StackObjectPoolFactory

public StackObjectPoolFactory(PoolableObjectFactory factory)

Create a new StackObjectPoolFactory.

Parameters:

factory - the PoolableObjectFactory used by created pools.

See Also:

StackObjectPool.StackObjectPool(PoolableObjectFactory)

StackObjectPoolFactory

public StackObjectPoolFactory(PoolableObjectFactory factory,
                              int maxIdle)

Create a new StackObjectPoolFactory.

Parameters:

factory - the PoolableObjectFactory used by created pools.

maxIdle - cap on the number of "sleeping" instances in the pool.

StackObjectPoolFactory

public StackObjectPoolFactory(PoolableObjectFactory factory,
                              int maxIdle,
                              int initIdleCapacity)

Create a new StackObjectPoolFactory.

Parameters:

factory - the PoolableObjectFactory used by created pools.

maxIdle - cap on the number of "sleeping" instances in the pool.

initIdleCapacity - - initial size of the pool (this specifies the size of the container, it does not cause the pool to be pre-populated.)
