Class ChainingFilter

java.lang.Object

net.shibboleth.shared.spring.servlet.impl.ChainingFilter

All Implemented Interfaces:

Filter

public class ChainingFilter
extends Object
implements Filter

Implementation of Filter that encapsulates and runs a chain of embedded filters in a defined order.

This is provided to deal with the problem of filter order when programmatic registration is done. Good or bad, some filters are order-sensitive and wishing that wasn't true doesn't change it.
