Catching Polymorphic Exceptions
Once you’ve created a polymorphic exception class, you can use it like any other exception class.
C++
try { // try to throw a custom exception of type MyException. throw MyException("Custom exception message"); } catch (const exception& e) { // catching the exception message and printing its // custom message. cerr << "Exception caught: " << e.what() << endl; } |
The catch block specifies a reference to ‘std::exception’, which can catch exceptions of the custom type or any derived classes.
Polymorphic Exceptions In C++
C++ is a powerful programming language that allows developers to handle errors and exceptional situations using exceptions. In this article, we will explore the concept of polymorphic exceptions in C++. Polymorphic exceptions allow you to create custom exception classes that can be caught at different levels of specificity, providing more detailed error information when needed. We’ll learn how to create and use polymorphic exception classes and understand their benefits in improving code clarity and maintainability.
Polymorphism in C++ allows different classes to be treated as objects of a common base class. This concept can be extended to exception handling.
