Java GenericVisitorAdapter: Simplify the Visitor Design Pattern

The visitor design pattern is a commonly used design pattern in object-oriented programming. It allows us to define a new operation on a set of objects without changing the classes of those objects. However, implementing the visitor pattern requires a lot of boilerplate code and can be cumbersome. Java GenericVisitorAdapter is a library that simplifies the implementation of the visitor pattern by using generics.

Java GenericVisitorAdapter provides a set of generic interfaces and classes that developers can use to implement the visitor pattern. The library defines the Visitor interface, which defines the visit method for each visited element. To implement a visitor, developers can extend the GenericVisitorAdapter class and override only the methods they need. This eliminates the need to write boilerplate code for every visitor implementation.

GenericVisitorAdapter also provides a set of abstract classes that provide default implementations for some of the Visitor interface methods. These abstract classes can be extended to further reduce the amount of code needed to implement a visitor.
