//! Defines an exception class \a C1 that inherits an exception class \a C2.

/*! \a C2 must be Standard_Failure or its ancestor.
|
|
The macro defines empty constructor, copy constructor and static methods Raise() and NewInstance().
|
|
Since Standard_Failure implements class manipulated by handle, DEFINE_STANDARD_RTTI macro is also
|
|
added to enable RTTI.
|
|
|
|
When using DEFINE_STANDARD_EXCEPTION in your code make sure you also insert a macro
|
|
DEFINE_STANDARD_HANDLE(C1,C2) before it.
