#define | DEFINE_STANDARD_EXCEPTION(C1, C2) |
Defines an exception class C1 that inherits an exception class C2. | |
#define | IMPLEMENT_STANDARD_EXCEPTION(C1) |
Implements an exception class C1 declared with DEFINE_STANDARD_EXCEPTION macro. |
#define DEFINE_STANDARD_EXCEPTION | ( | C1, | |
C2 | |||
) |
\ class C1 : public C2 { \ Standard_EXPORT virtual void Throw() const; \ public: \ C1() : C2() {} \ C1(const Standard_CString AString) : C2(AString) {} \ Standard_EXPORT static void Raise(const Standard_CString aMessage = ""); \ Standard_EXPORT static void Raise(Standard_SStream& aReason); \ Standard_EXPORT static Handle(C1) NewInstance(const Standard_CString aMessage = ""); \ \ DEFINE_STANDARD_RTTI(C1) \ };
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.
#define IMPLEMENT_STANDARD_EXCEPTION | ( | C1 | ) |
\ void C1::Raise(Standard_SStream& aReason) \ { \ Handle(C1) _E = new C1; \ _E->Reraise (aReason); \ } \ \ void C1::Raise(const Standard_CString AString) \ { \ Handle(C1) _E = new C1; \ _E->Reraise(AString); \ } \ \ Handle(C1) C1::NewInstance(const Standard_CString aMessage) \ { \ return new C1(aMessage); \ } \ void C1::Throw () const \ { \ throw *this; \ }
If you are using IMPLEMENT_STANDARD_EXCEPTION in your code make sure you also call IMPLEMENT_STANDARD_HANDLE(C1,C2) and IMPLEMENT_STANDARD_RTTIEXT(C1,C2).
