Constructor Details

CompressionPool

public CompressionPool(int capacity)

Create a Pool of CompressionPool instances. If given a capacity equal to zero the Objects will not be pooled and will be created on acquire and ended on release. If given a negative capacity equal to zero there will be no size restrictions on the Pool

Parameters:

capacity - maximum number of Objects which can be contained in the pool

Method Details

getCapacity

public int getCapacity()

setCapacity

public void setCapacity(int capacity)

newPooled

protected abstract T newPooled()

end

protected abstract void end(T object)

reset

protected abstract void reset(T object)

acquire

public CompressionPool<T>.Entry acquire()

Returns:

Object taken from the pool if it is not empty or a newly created Object

release

public void release(CompressionPool<T>.Entry entry)

Parameters:

entry - returns this Object to the pool or calls end(Object) if the pool is full.

doStart

protected void doStart()
                throws Exception

Description copied from class: AbstractLifeCycle

Method to override to start the lifecycle

Overrides:

doStart in class AbstractLifeCycle

Throws:

AbstractLifeCycle.StopException - If thrown, the lifecycle will immediately be stopped.

Exception - If there was a problem starting. Will cause a transition to FAILED state

doStop

public void doStop()
            throws Exception

Description copied from class: AbstractLifeCycle

Method to override to stop the lifecycle

Overrides:

doStop in class AbstractLifeCycle

Throws:
