cleanUp

protected void cleanUp()
                throws IOException

Do any clean up necessary to allow this instance to be used again.

When we get here, the Zip file has been closed and all we need to do is to reset some globals.

This method will only reset globals that have been changed during execute(), it will not alter the attributes or nested child elements. If you want to reset the instance so that you can later zip a completely different set of files, you must use the reset method.

Overrides:

cleanUp in class AbstractArchiver

Throws:

IOException

See Also:

reset()

reset

public void reset()

Makes this instance reset all attributes to their default values and forget all children.
