FilterRegistrationImpl

public FilterRegistrationImpl(FilterInfo filterInfo,
                              Deployment deployment,
                              ServletContextImpl servletContext)

Method Detail

addMappingForServletNames

public void addMappingForServletNames(EnumSet<DispatcherType> dispatcherTypes,
                                      boolean isMatchAfter,
                                      String... servletNames)

Description copied from interface: FilterRegistration

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.

Specified by:

addMappingForServletNames in interface FilterRegistration

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

getServletNameMappings

public Collection<String> getServletNameMappings()

Description copied from interface: FilterRegistration

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.

Specified by:

getServletNameMappings in interface FilterRegistration

Returns:

a (possibly empty) Collection of the currently available servlet name mappings of the Filter represented by this FilterRegistration

addMappingForUrlPatterns

public void addMappingForUrlPatterns(EnumSet<DispatcherType> dispatcherTypes,
                                     boolean isMatchAfter,
                                     String... urlPatterns)

Description copied from interface: FilterRegistration

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.

Specified by:

addMappingForUrlPatterns in interface FilterRegistration

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

getUrlPatternMappings

public Collection<String> getUrlPatternMappings()

Description copied from interface: FilterRegistration

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.

Specified by:

getUrlPatternMappings in interface FilterRegistration

Returns:

a (possibly empty) Collection of the currently available URL pattern mappings of the Filter represented by this FilterRegistration

getName

public String getName()

Description copied from interface: Registration

Gets the name of the Servlet or Filter that is represented by this Registration.

Specified by:

getName in interface Registration

Returns:

the name of the Servlet or Filter that is represented by this Registration

getClassName

public String getClassName()

Description copied from interface: Registration

Gets the fully qualified class name of the Servlet or Filter that is represented by this Registration.

Specified by:

getClassName in interface Registration

Returns:

the fully qualified class name of the Servlet or Filter that is represented by this Registration, or null if this Registration is preliminary

setInitParameter

public boolean setInitParameter(String name,
                                String value)

Description copied from interface: Registration

Sets the initialization parameter with the given name and value on the Servlet or Filter that is represented by this Registration.

Specified by:

setInitParameter in interface Registration

Parameters:

name - the initialization parameter name

value - the initialization parameter value

Returns:

true if the update was successful, i.e., an initialization parameter with the given name did not already exist for the Servlet or Filter represented by this Registration, and false otherwise

getInitParameter

public String getInitParameter(String name)

Description copied from interface: Registration

Gets the value of the initialization parameter with the given name that will be used to initialize the Servlet or Filter represented by this Registration object.

Specified by:

getInitParameter in interface Registration

Parameters:

name - the name of the initialization parameter whose value is requested

Returns:

the value of the initialization parameter with the given name, or null if no initialization parameter with the given name exists

setInitParameters

public Set<String> setInitParameters(Map<String,String> initParameters)

Description copied from interface: Registration

Sets the given initialization parameters on the Servlet or Filter that is represented by this Registration.

The given map of initialization parameters is processed by-value, i.e., for each initialization parameter contained in the map, this method calls Registration.setInitParameter(String,String). If that method would return false for any of the initialization parameters in the given map, no updates will be performed, and false will be returned. Likewise, if the map contains an initialization parameter with a null name or value, no updates will be performed, and an IllegalArgumentException will be thrown.

Specified by:

setInitParameters in interface Registration

Parameters:

initParameters - the initialization parameters

Returns:

the (possibly empty) Set of initialization parameter names that are in conflict

getInitParameters

public Map<String,String> getInitParameters()

Description copied from interface: Registration

Gets an immutable (and possibly empty) Map containing the currently available initialization parameters that will be used to initialize the Servlet or Filter represented by this Registration object.

Specified by:

getInitParameters in interface Registration

Returns:

Map containing the currently available initialization parameters that will be used to initialize the Servlet or Filter represented by this Registration object

setAsyncSupported

public void setAsyncSupported(boolean isAsyncSupported)

Description copied from interface: Registration.Dynamic

Configures the Servlet or Filter represented by this dynamic Registration as supporting asynchronous operations or not.

By default, servlet and filters do not support asynchronous operations.

A call to this method overrides any previous setting.

Specified by:

setAsyncSupported in interface Registration.Dynamic

Parameters:

isAsyncSupported - true if the Servlet or Filter represented by this dynamic Registration supports asynchronous operations, false otherwise
