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.
