Class JaxRsRestlet

java.lang.Object
  org.restlet.Uniform
      org.restlet.Restlet
          org.restlet.ext.jaxrs.JaxRsRestlet

public class JaxRsRestlet
extends Restlet

This class choose the JAX-RS resource class and method to use for a request and handles the result from he resource method. Typcally you should instantiate a JaxRsApplication to run JAX-RS resource classes.

The JAX-RS extension as well as the JAX-RS specification are currently under development. You should use this extension only for experimental purpose.
For further information see Java Service Request 311.

Concurrency note: instances of this class or its subclasses can be invoked by several threads at the same time and therefore must be thread-safe. You should be especially careful when storing state in member variables.

Constructor Detail

JaxRsRestlet

public JaxRsRestlet(Context context,
                    MetadataService metadataService)

Creates a new JaxRsRestlet with the given Context. Only the default providers are loaded. If a resource class later wants to check if a user has a role, the request is returned with HTTP status 500 (Internal Server Error), see SecurityContext.isUserInRole(String). You may set a RoleChecker by using the constructor JaxRsRestlet(Context, RoleChecker, MetadataService) or method setRoleChecker(RoleChecker).

Parameters:

context - the context from the parent, see Restlet.Restlet(Context).

metadataService - the metadata service of the JaxRsApplication.

JaxRsRestlet(Context, RoleChecker, MetadataService)

JaxRsRestlet

public JaxRsRestlet(Context context,
                    RoleChecker roleChecker,
                    MetadataService metadataService)

Creates a new JaxRsRestlet with the given Context. Only the default providers are loaded.

Parameters:

context - the context from the parent, see Restlet.Restlet(Context).

roleChecker - The RoleChecker to use. If you don't need the access control, you can use the RoleChecker.FORBID_ALL, the RoleChecker.ALLOW_ALL or the RoleChecker.REJECT_WITH_ERROR.

metadataService - the metadata service of the JaxRsApplication.

JaxRsRestlet(Context, MetadataService)

Method Detail

addClass

public boolean addClass(Class<?> jaxRsClass)
                 throws IllegalArgumentException

Will use the given JAX-RS root resource class.
If the given class is not a valid root resource class, a warning is logged and false is returned.

Parameters:

jaxRsClass - A JAX-RS root resource class or provider class to add. If the root resource class is already available in this JaxRsRestlet, it is ignored for later calls of this method.

Returns:

true if the class is added or was already included, or false if the given class is not a valid class (a warning was logged).

Throws:

IllegalArgumentException - if the root resource class is null.

addSingleton

public boolean addSingleton(Object jaxRsProviderOrRootresourceObject)
                     throws IllegalArgumentException

Adds the provider object to this JaxRsRestlet.

Parameters:

jaxRsProviderOrRootresourceObject - the JAX-RS provider or root resource object

Returns:

true, if the provider is ok and added, otherwise false.

Throws:

IllegalArgumentException - if null was given

start

public void start()
           throws Exception

Overrides:

start in class Restlet

Throws:

Exception

handle

public void handle(Request request,
                   Response response)

Handles a call by looking for the resource metod to call, call it and return the result.

Overrides:

handle in class Restlet

Parameters:

request - The Request to handle.

response - The Response to update.

getRoleChecker

public RoleChecker getRoleChecker()

Gets the currently used RoleChecker.

Returns:

the currently used RoleChecker.

See Also:

setRoleChecker(RoleChecker)

setRoleChecker

public void setRoleChecker(RoleChecker roleChecker)
                    throws IllegalArgumentException

Sets the RoleChecker to use.

Parameters:

roleChecker - the roleChecker to set. Must not be null. Take a look at RoleChecker.ALLOW_ALL, RoleChecker.FORBID_ALL and RoleChecker.REJECT_WITH_ERROR.

Throws:

IllegalArgumentException - If the given roleChecker is null.

RoleChecker, getRoleChecker()

getRootResourceClasses

public Set<Class<?>> getRootResourceClasses()

Returns an unmodifiable set with the attached root resource classes.

Returns:

an unmodifiable set with the attached root resource classes.

getRootUris

public Collection<String> getRootUris()

Returns a Collection with all root uris attached to this JaxRsRestlet.

Returns:

a Collection with all root uris attached to this JaxRsRestlet.

getObjectFactory

public ObjectFactory getObjectFactory()

Returns the ObjectFactory for root resource class and provider instantiation, if given.

Returns:

the ObjectFactory for root resource class and provider instantiation, if given.

setObjectFactory

public void setObjectFactory(ObjectFactory objectFactory)

Sets the ObjectFactory for root resource class and provider instantiation.

Parameters:

objectFactory - the ObjectFactory for root resource class and provider instantiation.
