Interface through which a Filter may be further configured.

Since:
Servlet 3.0
 
 public interface FilterRegistration extends Registration {

    
Adds a filter mapping with the given servlet names and dispatcher types for the Filter represented by this FilterRegistration.

Filter mappings are matched in the order in which they were added.

Depending on the value of the isMatchAfter parameter, the given filter mapping will be considered after or before any declared filter mappings of the ServletContext from which this FilterRegistration was obtained.

If this method is called multiple times, each successive call adds to the effects of the former.

Parameters:
dispatcherTypes the dispatcher types of the filter mapping, or null if the default DispatcherType.REQUEST is to be used
isMatchAfter true if the given filter mapping should be matched after any declared filter mappings, and false if it is supposed to be matched before any declared filter mappings of the ServletContext from which this FilterRegistration was obtained
servletNames the servlet names of the filter mapping
Throws:
java.lang.IllegalArgumentException if servletNames is null or empty
java.lang.IllegalStateException if the ServletContext from which this FilterRegistration was obtained has already been initialized
 
     public void addMappingForServletNames(
         EnumSet<DispatcherTypedispatcherTypesboolean isMatchAfter,
         String... servletNames);

    
Gets the currently available servlet name mappings of the Filter represented by this FilterRegistration.

If permitted, any changes to the returned Collection must not affect this FilterRegistration.

Returns:
a (possibly empty) Collection of the currently available servlet name mappings of the Filter represented by this FilterRegistration
 
     public Collection<StringgetServletNameMappings();

    
Adds a filter mapping with the given url patterns and dispatcher types for the Filter represented by this FilterRegistration.

Filter mappings are matched in the order in which they were added.

Depending on the value of the isMatchAfter parameter, the given filter mapping will be considered after or before any declared filter mappings of the ServletContext from which this FilterRegistration was obtained.

If this method is called multiple times, each successive call adds to the effects of the former.

Parameters:
dispatcherTypes the dispatcher types of the filter mapping, or null if the default DispatcherType.REQUEST is to be used
isMatchAfter true if the given filter mapping should be matched after any declared filter mappings, and false if it is supposed to be matched before any declared filter mappings of the ServletContext from which this FilterRegistration was obtained
urlPatterns the url patterns of the filter mapping
Throws:
java.lang.IllegalArgumentException if urlPatterns is null or empty
java.lang.IllegalStateException if the ServletContext from which this FilterRegistration was obtained has already been initialized
    public void addMappingForUrlPatterns(
        EnumSet<DispatcherTypedispatcherTypesboolean isMatchAfter,
        String... urlPatterns);

    
Gets the currently available URL pattern mappings of the Filter represented by this FilterRegistration.

If permitted, any changes to the returned Collection must not affect this FilterRegistration.

Returns:
a (possibly empty) Collection of the currently available URL pattern mappings of the Filter represented by this FilterRegistration
    public Collection<StringgetUrlPatternMappings();

    
Interface through which a Filter registered via one of the addFilter methods on ServletContext may be further configured.
    interface Dynamic extends FilterRegistrationRegistration.Dynamic {
    }
