virtual CorrelationId IT_Bus::DispatchInfo::get_correlation_id

(

)

Returns an identifier which is unique to the operation that this DispatchInfo represents.

It can be used to correlate the incoming and outgoing messages associated with the same operation in ServerMessageInterceptor:: message_received and send_message calls.

Returns:

correlation identifier.

virtual ContextContainer& IT_Bus::DispatchInfo::get_incoming_context_container

(

)

[pure virtual]

Return the incoming context container for this operation.

Returns:

Incoming context container.

virtual ContextContainer& IT_Bus::DispatchInfo::get_outgoing_context_container

(

)

[pure virtual]

Return the outgoing context container for this operation.

Returns:

Outgoing context container.

virtual bool IT_Bus::DispatchInfo::is_oneway

(

)

const [pure virtual]

In ServerMessageInterceptor::send_message() this returns true of the operation is one-way false otherwise.

This function does not return a meaningful value in ServerMessageInterceptor::message_received().

Returns:

[pure virtual]

The following method may be called to get an exception that might have occurred during the server-side dispatch.

The caller must not delete the exception returned from this method.

virtual void IT_Bus::DispatchInfo::provide_response_buffer

(

BinaryBuffer &

response_buffer

)

[pure virtual]

The following method may ONLY be called by transports advertizing the policy POLICY_REQUIRES_SYNCHRONOUS_DISPATCH.

This method must be called to provide a reference to the stack allocated BinaryBuffer. The caller may expect the BinaryBuffer to contain the reply message after TransportCallback::dispatch() returns.

Parameters:

response_buffer

Buffer which will hold the response message.
