accept

public void accept(PolymorphicVisitor pv)

Description copied from interface: PolymorphicVisitable

This method is intended to extend the semantics of method Visitable.accept(Visitor)

In a conventional Visitor design pattern, the accept method is called when access to visit a data structure is requested. A Visitor object is passed as argument in case permission is granted to that Visitor to access the data structure. Obviously, Visitors and Visitables work in pairs and the class which provides the data structure to be visited also implements Visitable in order to properly grant access when the expected Visitor is received.

In the case of a PolymorphicVisitable, a PolymorphicVisitor is passed instead of a Visitor. A PolymorphicVisitor is in fact, a composition of Visitors and not only a single Visitor. A PolymorphicVisitor is responsible for returning the correct Visitor responsible for processing a certain data structure.

The initial design of pairs made of <Visitor,Visitable> is extended to a concept of a matrix made of multiple Visitors against multiple Visitables. Every class which implements PolymorphicVisitable passes different data structures when querying PolymorphicVisitors.
