Declaration of Throws for Generic Exception

Opis

The product throws or raises an overly broad exceptions that can hide important details and produce inappropriate responses to certain conditions.

Declaring a method to throw Exception or Throwable promotes generic error handling procedures that make it difficult for callers to perform proper error handling and error recovery. For example, Java's exception mechanism makes it easy for callers to anticipate what can go wrong and write code to handle each specific exceptional circumstance. Declaring that a method throws a generic form of exception defeats this system.

Uwagi

For C++, this weakness only applies to C++98, C++03, and C++11. It relies on a feature known as Dynamic Exception Specification, which was part of early versions of C++ but was deprecated in C++11. It has been removed for C++17 and later.
