Java GenericVisitorAdapter: What is it and How Does it Work?
If you are a Java developer, then you may be familiar with the concept of the Visitor pattern. The Visitor pattern is used to separate an algorithm from an object structure on which it operates. Java provides a GenericVisitor interface that can be implemented to create a visitor, but this interface can be cumbersome to implement. This is where the Java GenericVisitorAdapter comes in.
The Java GenericVisitorAdapter is a pre-defined implementation of the GenericVisitor interface that provides default implementations for all the visit methods. This means that you can extend the GenericVisitorAdapter and only override the methods that you need to implement. This makes it much easier to create a visitor.
To use the Java GenericVisitorAdapter, you simply need to extend the class and implement the visit methods that you need to use. For example, if you have a class hierarchy that you want to visit, you can extend the GenericVisitorAdapter and implement the visit methods for each of the classes in the hierarchy.
