public void visit(Predicate p)
Node
Each class has a visit(Predicate p) method. For
example, in class ABC:
public void visit(Predicate p)
{
p.visitABC(this);
}
and the class that implements Predicate has a method
public void visitABC(Node n)
{
ABC a = (ABC) n;
...
}
Thus, the class that implements Predicate can call
n.visit(this);where
n is a Node sub-class without
determining which specific sub-class n is.
The visit pattern basically avoids implementing a large
switch statement or defining different methods
in each class for some purpose.
