Constructor Detail

ServletRegistrationImpl

public ServletRegistrationImpl(ServletInfo servletInfo,
                               ManagedServlet managedServlet,
                               Deployment deployment)

Method Detail

setLoadOnStartup

public void setLoadOnStartup(int loadOnStartup)

Description copied from interface: ServletRegistration.Dynamic

Sets the loadOnStartup priority on the Servlet represented by this dynamic ServletRegistration.

A loadOnStartup value of greater than or equal to zero indicates to the container the initialization priority of the Servlet. In this case, the container must instantiate and initialize the Servlet during the initialization phase of the ServletContext, that is, after it has invoked all of the ServletContextListener objects configured for the ServletContext at their ServletContextListener.contextInitialized(javax.servlet.ServletContextEvent) method.

If loadOnStartup is a negative integer, the container is free to instantiate and initialize the Servlet lazily.

The default value for loadOnStartup is -1.

A call to this method overrides any previous setting.

Specified by:

setLoadOnStartup in interface ServletRegistration.Dynamic

Parameters:

loadOnStartup - the initialization priority of the Servlet

setServletSecurity

public Set<String> setServletSecurity(ServletSecurityElement constraint)

Description copied from interface: ServletRegistration.Dynamic

Sets the ServletSecurityElement to be applied to the mappings defined for this ServletRegistration.

This method applies to all mappings added to this ServletRegistration up until the point that the ServletContext from which it was obtained has been initialized.

If a URL pattern of this ServletRegistration is an exact target of a security-constraint that was established via the portable deployment descriptor, then this method does not change the security-constraint for that pattern, and the pattern will be included in the return value.

If a URL pattern of this ServletRegistration is an exact target of a security constraint that was established via the ServletSecurity annotation or a previous call to this method, then this method replaces the security constraint for that pattern.

If a URL pattern of this ServletRegistration is neither the exact target of a security constraint that was established via the ServletSecurity annotation or a previous call to this method, nor the exact target of a security-constraint in the portable deployment descriptor, then this method establishes the security constraint for that pattern from the argument ServletSecurityElement.

Specified by:

setServletSecurity in interface ServletRegistration.Dynamic

Parameters:

constraint - the ServletSecurityElement to be applied to the patterns mapped to this ServletRegistration

Returns:

the (possibly empty) Set of URL patterns that were already the exact target of a security-constraint that was established via the portable deployment descriptor. This method has no effect on the patterns included in the returned set

setMultipartConfig

public void setMultipartConfig(MultipartConfigElement multipartConfig)

Description copied from interface: ServletRegistration.Dynamic

Sets the MultipartConfigElement to be applied to the mappings defined for this ServletRegistration. If this method is called multiple times, each successive call overrides the effects of the former.

Specified by:

setMultipartConfig in interface ServletRegistration.Dynamic

Parameters:

multipartConfig - the MultipartConfigElement to be applied to the patterns mapped to the registration

setRunAsRole

public void setRunAsRole(String roleName)

Description copied from interface: ServletRegistration.Dynamic

Sets the name of the runAs role for this ServletRegistration.

Specified by:

setRunAsRole in interface ServletRegistration.Dynamic

Parameters:

roleName - the name of the runAs role

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

addMapping

public Set<String> addMapping(String... urlPatterns)

Description copied from interface: ServletRegistration

Adds a servlet mapping with the given URL patterns for the Servlet represented by this ServletRegistration.

If any of the specified URL patterns are already mapped to a different Servlet, no updates will be performed.

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

Specified by:

addMapping in interface ServletRegistration

Parameters:

urlPatterns - the URL patterns of the servlet mapping

Returns:

the (possibly empty) Set of URL patterns that are already mapped to a different Servlet

getMappings

public Collection<String> getMappings()

Description copied from interface: ServletRegistration

Gets the currently available mappings of the Servlet represented by this ServletRegistration.

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

Specified by:

getMappings in interface ServletRegistration

Returns:

a (possibly empty) Collection of the currently available mappings of the Servlet represented by this ServletRegistration

getRunAsRole

public String getRunAsRole()

Description copied from interface: ServletRegistration

Gets the name of the runAs role of the Servlet represented by this ServletRegistration.

Specified by:

getRunAsRole in interface ServletRegistration

Returns:

the name of the runAs role, or null if the Servlet is configured to run as its caller

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
