java.lang.Object
  org.objectweb.jeremie.services.handler.lib.DavidServicesHandler

All Implemented Interfaces:

ServicesHandler

public class DavidServicesHandler

extends Object

implements ServicesHandler

Default implementation of a ServicesHandler.

The services managed by this handler must be components of a Context provided at initialization time. The names to use should be integers representing service identifiers. The service components' values must be Service instances.

The list of services managed by a DavidServicesHandler instance is initialized when the instance is created.

Constructor Summary

DavidServicesHandler(org.objectweb.jonathan.apis.kernel.Context services_context)
Builds a new DavidServicesHandler instance.

Method Summary

ServiceContext[]	getReplyContexts(int request_id, org.objectweb.jonathan.apis.kernel.Context message_context) Returns a list of service contexts.
ServiceContext[]	getRequestContexts(int request_id, boolean response_expected, byte[] object_key, org.objectweb.jonathan.apis.kernel.Context message_context) Returns a list of service contexts.
void	handleReplyContexts(ServiceContext[] contexts, int request_id, org.objectweb.jonathan.apis.kernel.Context message_context) Lets the handler manage the provided contexts.
void	handleRequestContexts(ServiceContext[] contexts, int request_id, boolean response_expected, byte[] object_key, org.objectweb.jonathan.apis.kernel.Context message_context) Lets the handler manage the provided contexts.

DavidServicesHandler

public DavidServicesHandler(org.objectweb.jonathan.apis.kernel.Context services_context)
                     throws org.objectweb.jonathan.apis.kernel.JonathanException

Builds a new DavidServicesHandler instance.

Parameters:

services_context - the context containing the services (as local objects);

Throws:

org.objectweb.jonathan.apis.kernel.JonathanException - if something goes wrong

Method Detail

getRequestContexts

public ServiceContext[] getRequestContexts(int request_id,
                                           boolean response_expected,
                                           byte[] object_key,
                                           org.objectweb.jonathan.apis.kernel.Context message_context)

Returns a list of service contexts.

This method simply tries to get a request context from each managed service. No service order is specified.

Specified by:

getRequestContexts in interface ServicesHandler

Parameters:

request_id - the request id;

response_expected - indicates if a response is expected;

object_key - the target object key.

message_context - the context of the request marshaller.

Returns:

a list of service contexts.

getReplyContexts

public ServiceContext[] getReplyContexts(int request_id,
                                         org.objectweb.jonathan.apis.kernel.Context message_context)

Returns a list of service contexts.

This method simply tries to get a reply context from each managed service. No service order is specified.

Specified by:

getReplyContexts in interface ServicesHandler

Parameters:

request_id - the request id.

message_context - the context of the reply marshaller.

Returns:

a list of service contexts.

handleRequestContexts

public void handleRequestContexts(ServiceContext[] contexts,
                                  int request_id,
                                  boolean response_expected,
                                  byte[] object_key,
                                  org.objectweb.jonathan.apis.kernel.Context message_context)

Lets the handler manage the provided contexts.

When a context bears the same identifier as one of the services handled by the target handler, the context is sent to the service. No order is specified.

Specified by:

handleRequestContexts in interface ServicesHandler

Parameters:

contexts - the list of contexts contained in the request;

request_id - the request id;

response_expected - indicates whether a response is expected;

object_key - the target object key.

message_context - the context of the request unmarshaller.

handleReplyContexts

public void handleReplyContexts(ServiceContext[] contexts,
                                int request_id,
                                org.objectweb.jonathan.apis.kernel.Context message_context)

Lets the handler manage the provided contexts.

When a context bears the same identifier as one of the services handled by the target handler, the context is sent to the service. No order is specified.

Specified by:

handleReplyContexts in interface ServicesHandler

Parameters:

contexts - the list of contexts contained in the reply;

request_id - the request id;

message_context - the context of the reply unmarshaller.
