ClientRequestInfoOperations (GNU libgcj 4.4.3 Documentation)

Provides request information, accessible for the ClientRequestInterceptor. Some methods of this interface are not valid at all interception points. The following table shows the validity of each method. If it is not valid, BAD_INV_ORDER minor 14 will be thrown.

	send_request	send_poll	receive_reply	receive_exception	receive_other
Inherited from RequestInfoOperations:

get_effective_components	yes	no	yes
get_request_policy	yes	no	yes
add_request_service_context	yes	no
	send_request	send_poll	receive_reply	receive_exception	receive_other

When ClientRequestInfo is passed to send_request, there is an entry in the list for every argument, but only the in and inout arguments will be available.
If the reply_status atribute is not LOCATION_FORWARD, accessing this attribute will throw BAD_INV_ORDER with a standard minor code of 14.

Method Summary
void	add_request_service_context(ServiceContext service_context, boolean replace) Allows the interceptor to add the service contexts to the request.
TaggedProfile	effective_profile() Returns the tagged profile (IOR) of the invocation target.
Object	effective_target() Returns the object on that the operation will be invoked after handling the possible forwarding.
TaggedComponent	get_effective_component(int id) Returns the given component of the invocation target profile.
TaggedComponent[]	get_effective_components(int id) Returns the given components of the invocation target profile.
Policy	get_request_policy(int type) This should return the policy of the given type that applies to this operation, but it is not implemented up till JDK 1.5 inclusive.
Any	received_exception() Returns the remote exception that was thrown on the server side.
String	received_exception_id() Returns the repository id of the remote exception that was thrown on the server side.
Object	target() Returns the object on that the client has invoked the the operation.

Method Detail

add_request_service_context

Allows the interceptor to add the service contexts to the request. Such added contexts can carry arbitrary data and can be later accessed on the server side by the server request interceptor, using RequestInfoOperations.

Parameters: service_context the context to add. replace if true, the existing context with the same Id will be replaced. If false, the BAD_INV_ORDER will be thrown in that case.

Throws: BAD_INV_ORDER minor 15 if the context with the same Id already exists and replace=false.

effective_profile

Returns the tagged profile (IOR) of the invocation target. If the request was forwarded, the method returns the new location, shown by the forwarding message.

Returns: the invocation IOR.

effective_target

Returns the object on that the operation will be invoked after handling the possible forwarding.

Returns: the final invocation target.
