Package org.omg.PortableInterceptor Description

Provides a mechanism to register ORB hooks through which ORB services can intercept the normal flow of execution of the ORB.

Interceptor Types

There are currently three types of interceptors that can be registered:

• IORInterceptor - Used to establish tagged components in the profiles within an IOR.
• ClientRequestInterceptor - Intercepts the flow of a request/reply sequence through the ORB on the client side.
• ServerRequestInterceptor - Intercepts the flow of a request/reply sequence through the ORB on the server side.

See the javadocs for class ORBInitializer for how to go about registering interceptors.

Known limitations / unimplemented methods in package org.omg.PortableInterceptor

• RequestInfo
  • sync_scope(): Always returns SYNC_WITH_TRANSPORT
  • arguments(): Only supported for DII/DSI calls
  • exceptions(): Only supported for DII calls on client side. Not supported on server-side.
  • contexts(): Only supported for DII calls on client side. Not supported on server-side since our ORB does not send contexts.
  • operation_context(): Only supported for DII calls on client side. Not supported on server-side since ORB does not send contexts.
  • result(): Only supported for DII/DSI calls
• ClientRequestInfo
  • received_exception_id(): Always returns null in the DII case
  • get_request_policy(int type): Not implemented.
• ServerRequestInfo
  • sending_exception(): Does not support user exceptions on the server side in non-DSI case.
