deferred class ErrorHandlerCallback from Standard
|
|
|
|
---Purpose: Defines a base class for callback objects that can be registered
|
|
-- in the OCC error handler (the class simulating C++ exceptions)
|
|
-- so as to be correctly destroyed when error handler is activated.
|
|
--
|
|
-- Note that this is needed only when Open CASCADE is compiled with
|
|
-- NO_CXX_EXCEPTION or OCC_CONVERT_SIGNALS options (i.e. on UNIX/Linux).
|
|
-- In that case, raising OCC exception and/or signal will not cause
|
|
-- C++ stack unwinding and destruction of objects created in the stack.
|
|
--
|
|
-- This class is intended to protect critical objects and operations in
|
|
-- the try {} catch {} block from being bypassed by OCC signal or exception.
|
|
--
|
|
-- Inherit your object from that class, implement DestroyCallback() function,
|
|
-- and call Register/Unregister in critical points.
|
|
--
|
|
-- Note that you must ensure that your object has life span longer than
|
|
-- that of the try {} block in which it calls Register().

---Purpose: Registers this callback object in the current error handler

UnregisterCallback (me: in out);
|
|
---Purpose: Unregisters this callback object from the error handler.

|
|
---Purpose: The callback function to perform necessary callback action.
|
|
-- Called by the exception handler when it is being destroyed but
|
|
-- still has this callback registered.
