public @Interface DestroyMethod

Designates a method corresponding to the portlet API destroy method. The annotated method must have the following signature:

public void <methodName>()

where the method name can be freely selected.

the destroy method is called by the portlet container to indicate to a portlet that the portlet is being taken out of service.

Before the portlet container calls the destroy method, it should allow any threads that are currently processing requests within the portlet object to complete execution. To avoid waiting forever, the portlet container can optionally wait for a predefined time before destroying the portlet object.

This method enables the portlet to do the following:

• clean up any resources that it holds (for example, memory, file handles, threads)
• make sure that any persistent state is synchronized with the portlet current state in memory.
