Java GenericVisitorAdapter – Effective Implementation of the Visitor Pattern
The visitor pattern is a GoF (Gang of Four) design pattern that helps in separating the logic of an element from its structural representation, thus, providing greater flexibility and extensibility to the codebase. However, implementing the visitor pattern in Java can prove to be a daunting task. Java GenericVisitorAdapter eases the implementation of the visitor pattern and provides a more effective way of traversing the hierarchy of objects.
Java GenericVisitorAdapter is a class that extends the Visitor interface provided by the Visitor design pattern. It provides a default implementation of the visit method for all the elements defined in the hierarchy. This eliminates the need to define the visit method for all the elements, which can be a tedious and error-prone process.
The Java GenericVisitorAdapter also provides an overloaded version of the visit method, which takes as a parameter an object of type T. This allows for a more generic implementation of the visit method, as it can now be used to visit any object that extends the hierarchy defined in T. This is in contrast to the traditional visitor pattern, where a separate visit method had to be defined for each element of the hierarchy.
