public DoVisitor()

Method Detail

visit

public void visit(ICarPart anElement)

Abstract definition of the Visitor's Pattern visit method. This method will alone handle the dynamic double-dispatch operation avoiding the need for a counterpart accept method in the IElement hierarchy. First the visit method will resolve to the base Visitor implementation's by dynamic invocation i.e. overriding. Then the base Visitor implementation will lookup automatically by a second dynamic dispatch mechanism the right Visitor's visit implementation depending on the concrete IElement sub-type.

Specified by:

visit in interface IVisitor<ICarPart>

anElement - IElement instance to visit.
