Helper methods for making different types of invocations. | |
These methods useful for various types of invocations like SII, AMI, DII and DSI. All the subclasses implement these methods to get the right behaviour at their level. | |

The main objective of this class is to adapt the type and invocation specific information declared in the IDL by the application and convert them as CORBA invocations to the target object. Implementation of this class knows how to make invocations on a collocated or a remote object.
This adapter class serves as the base class for various types of invocations like AMI, DII, DSI etc. Adapter classes for AMI, DII, DSI inherit from this class and their local behavioural information before kicking off an invocation.
@ More info.. Wafer thin inclusions All stuff created on stack Only handles starts and restarts

Helper method that extracts TAO_Stub from the target object.
|
|
||||||||||||
|
Helper function that extracts the roundtrip timeout policies set in the ORB. |
|
||||||||||||
|
Invoke the target, and used by the generated code. The implementation decides whether the target is remote or collocated and takes the right decision.
|
|
||||||||||||||||||||
|
Make a collocated call. This method creates an object that takes care of making collocated invocations and calls invoke () on it. If the invoke () returns with a location forwarded reply we return a restart
|
|
||||||||||||
|
The stub pointer passed to this call has all the details about the object to which the invocation needs to be routed to. The implementation of this method looks if we are collocated or not and takes care of reinvoking the target if it receives forwarding information or if the first invocation fails for some reason, like a loss of connection during send () etc. |
|
||||||||||||||||||||
|
Helper method to make a one way invocation. This method creates a synchronous oneway invocation object to which the actual task of request handling is delegated. Once the invocation returns this method checks whether the request is forwarded to a new location to take appropriate action. |
|
||||||||||||||||||||
|
Helper method that prepares the necessary stuff for a remote invocation. |
|
||||||||||||||||||||
|
Helper method to make a two way invocation. This method creates a synchronous twoway invocation object to which the actual task of request handling is delegated. Once the invocation returns this method checks whether the request is forwarded to a new location. |
|

|
Helper method that takes care of setting the profiles within the stub object if the target gets forwarded |
