Package hudson.util

Class PluginServletFilter

java.lang.Object

hudson.util.PluginServletFilter

All Implemented Interfaces:

ExtensionPoint, javax.servlet.Filter

public final class PluginServletFilter
extends Object
implements javax.servlet.Filter, ExtensionPoint

Servlet Filter that chains multiple Filters, provided by plugins

While this class by itself is not an extension point, I'm marking this class as an extension point so that this class will be more discoverable.

SecurityRealm that wants to contribute Filters should first check if SecurityRealm.createFilter(FilterConfig) is more appropriate.
