Detailed Description

Class used to make copying between request scope current and thread scope current exception-safe.

Since copies between the request scope current and thread scope current must also occur if an exception is thrown, e.g. made available to the send_exception() interception points, the "guard" idiom is used to make this action exception-safe.

Note

This Guard class is only used on the server side.

Constructor & Destructor Documentation

TAO::PICurrent_Guard::PICurrent_Guard	(	TAO_ServerRequest &	server_request,
		bool	tsc_to_rsc
	)

Constructor.

This constructor sets up this guard to copy the data held in a given PICurrent when transitioning from that PICurrent's scope to another scope (e.g. request scope to thread scope transition immediately following receive_request_service_contexts() on server side).

Parameters

tsc_to_rsc

true when copying TSC slot table to RSC slot table, i.e. after target operation completes.

TAO::PICurrent_Guard::~PICurrent_Guard

(

void

)

Destructor.

The destructor copies (a logical copy whenever possible) data held in a given PICurrent when transitioning from one PICurrent scope to another immediately before any ending interception points are invoked, and after the starting and intermediate (if any) interception points are invoked.
