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

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.
