      com.atlassian.plugin.servlet.descriptors.BaseServletModuleDescriptor<javax.servlet.Filter>
          com.atlassian.plugin.servlet.descriptors.ServletFilterModuleDescriptor

All Implemented Interfaces:

ModuleDescriptor<javax.servlet.Filter>, Resourced, StateAware

public class ServletFilterModuleDescriptor
extends BaseServletModuleDescriptor<javax.servlet.Filter>
implements StateAware

A module descriptor that allows plugin developers to define servlet filters. Developers can define what urls the filter should be applied to by defining one or more <url-pattern> elements and they can decide where in the filter stack a plugin filter should go by defining the "location" and "weight" attributes.

The location attribute can have one of four values:

• after-encoding - after the character encoding filter
• before-login - before the login filter
• before-decoration - before any global decoration like sitemesh
• before-dispatch - before any dispatching filters or servlets

The default for the location attribute is "before-dispatch".

The weight attribute can have any integer value. Filters with lower values of the weight attribute will come before those with higher values within the same location.

Since:

2.1.0
