Java GenericVisitorAdapter: Making Visitor Pattern More Generic and Flexible

The Visitor pattern is widely used in object-oriented programming to separate algorithms from the objects they operate on. It allows you to define new operations on an object structure without having to modify the classes that make up the structure. However, the standard implementation of the Visitor pattern can become overly complex and cumbersome when dealing with a large number of classes in the object hierarchy.

This is where the Java GenericVisitorAdapter comes in. It is a generic implementation of the Visitor pattern in Java that allows you to easily define new operations on an object hierarchy without the need for a separate Visitor interface for each operation.

The GenericVisitorAdapter provides two important benefits. First, it reduces the amount of boilerplate code required to implement the Visitor pattern. Second, it allows you to easily add new operations to an object hierarchy without the need to modify the existing Visitor interface.
