destroy
public void destroy()
- Description copied from interface:
Filter
- Called by the web container to indicate to a filter that it is being taken out of service. This
method is only called once all threads within the filter's doFilter method have exited or after
a timeout period has passed. After the web container calls this method, it will not call the
doFilter method again on this instance of the filter.
This method gives the filter an opportunity to clean up any resources that are being held (for
example, memory, file handles, threads) and make sure that any persistent state is synchronized
with the filter's current state in memory.
