Interface InteractionVisitor<A1,A2,A3>

Type Parameters:

A1 - the type of the first argument

A2 - the type of the second argument

A3 - the type of the third argument

public interface InteractionVisitor<A1,A2,A3>

This interface describes a visitor for interaction modes. With the help of this interface the visitor pattern can be implemented.

The user of the visitor pattern has to provide an implementation of this interface. Then the visit method is invoked and the caller is forwarded to the appropriate visit method in the visitor.

Consider we have a mode constant at hand which is in fact a batch mode and we invokes

   boolean boo = mode.visit(visitor, a, b, c);
 

then the following method in the object visitor is used:

   visitBatchmode(visitor, a, b, c)
