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.
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).
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.
PICurrent_Impl* TAO::PICurrent_Guard::dest_ [private] |
The PICurrent implementation whose slot table will be filled with the contents of another PICurrent's slot table.
PICurrent_Impl* TAO::PICurrent_Guard::src_ [private] |
The PICurrent implementation whose slot table will be copied.
