Data Structures
class	Callback
	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. More...

Public Member Functions
	Standard_ErrorHandler ()
	Create a ErrorHandler (to be used with try{}catch(){}). It uses the "setjmp" and "longjmp" routines.
void	Destroy ()
	Unlinks and checks if there is a raised exception.
	~Standard_ErrorHandler ()
	Destructor.
void	Unlink ()
	Removes handler from the handlers list.
Standard_Boolean	Catches (const Handle< Standard_Type > &aType)
	Returns "True" if the caught exception has the same type or inherits from "aType".
Standard_JmpBuf &	Label ()
	Returns label for jump.
Handle< Standard_Failure >	Error () const
	Returns the current Error.

Static Public Member Functions
static Handle< Standard_Failure >	LastCaughtError ()
	Returns the caught exception.
static Standard_Boolean	IsInTryBlock ()
	Test if the code is currently running in a try block.

Detailed Description

Class implementing mechanics of conversion of signals to exceptions.

Each instance of it stores data for jump placement, thread id, and callbacks to be called during jump (for proper resource release).

The active handlers are stored in the global stack, which is used to find appropriate handler when signal is raised.
