public class ExceptionHandler
extends CompoundStatement

Represents an exception handling block (try-catch-finally block) in a C++ or Java program. This class is derived from CompoundStatement because in C++ it is legal to have a procedure whose body is an exception handler. An exception handler has a try block followed by at least one catch block followed optionally by a finally block.
