public void recycle(ServletResponse res)

Recycles a wrapper with a response.

Parameters:

res - the wrapped response.

recycle

public void recycle()

Description copied from interface: Recyclable

Recycles the object for a new client. Recycle methods with parameters must be added to implementing object and they will be automatically called by pool implementations when the object is taken from the pool for a new client. The parameters must correspond to the parameters of the constructors of the object. For new objects, constructors can call their corresponding recycle methods whenever applicable. The recycle methods must call their super.

Specified by:

recycle in interface Recyclable

dispose

public void dispose()

Description copied from interface: Recyclable

Disposes the object after use. The method is called when the object is returned to its pool. The dispose method must call its super.

Specified by:

dispose in interface Recyclable

isDisposed

public boolean isDisposed()

Description copied from interface: Recyclable

Checks whether the recyclable has been disposed.

Specified by:

isDisposed in interface Recyclable

Returns:

true, if the recyclable is disposed.

recycled

public void recycled(MBeanReference instance)

Description copied from interface: Poolable

A callback specifying the pool, from which this instance was recycled.

Specified by:
