Member Function: TVideoException::Throw

virtual void Throw () const

Interface Category:

API.

Purpose:

Throws this exception object. Differs from a standard C++ throw *this; where the thrown object is a clone of the argument object. The standard C++ throw would cut the object back to a TStandardException, thereby losing all information embodied by the derived class, which, for TStandardExceptions, is everything.

Calling Context:

Call this function directly.

Parameters:

Takes no parameters.

Return Value:

None.

Exceptions:

Implements exceptions throw.

Concurrency:

Multithread safe.

Other Considerations:

All derived classes of TStandardException must override Throw like this: TMySubClass::Throw() const { throw *this;}.
