public interface FilterChain
A FilterChain
is an object provided by the portlet container
to the developer giving a view into the invocation chain of a
filtered request for a portlet. Filters use the FilterChain
to invoke the next filter in the chain, or if the calling filter is the
last filter in the chain, to invoke the portlet at the end of the chain.
