Stack: Difference between revisions

Unwinding the stack is complex. It is done when using exceptions, like in [[C PlusPlus|C++]]. It is performed when an exception is thrown. The purpose of unwinding the stack is to call the destructor of local objects of the stack frames and to remove stack frames until an appropriate landing pad is found. The landing pad is the try..catch block in C++ or Java. The catch block has to match the exception, i.e. a RuntimeException object can't be caught as a String object.
