Method Detail

getObject

public Object getObject(Object param)
                 throws PoolException

Description copied from interface: Pool

Get an object from the pool within the specified time. The amount of time the calling thread agrees to wait. Some value that might be used while creating the object

Specified by:

getObject in interface Pool

Overrides:

getObject in class NonBlockingPool

Returns:

an Object or null if an object could not be returned in 'waitForMillis' millisecond.

Throws:

PoolException - if an object cannot be created

returnObject

public void returnObject(Object object)

Return an object back to the pool. An object that is obtained through getObject() must always be returned back to the pool using either returnObject(obj) or through destroyObject(obj).

Specified by:

returnObject in interface Pool

Overrides:

returnObject in class NonBlockingPool

destroyObject

public void destroyObject(Object object)

Destroys an Object. Note that applications should not ignore the reference to the object that they got from getObject(). An object that is obtained through getObject() must always be returned back to the pool using either returnObject(obj) or through destroyObject(obj). This method tells that the object should be destroyed and cannot be reused.

Specified by:

destroyObject in interface Pool

Overrides:

destroyObject in class NonBlockingPool

Parameters:

object - Object to be destroyed.

remove

protected void remove(int count)

Overrides:

remove in class NonBlockingPool
