public interface DifferenceVisitor<T,A>
A visitor for visiting all types of differences.
All difference classes should implement a double-dispatch method as follows:
public <T, A> T accept(DifferenceVisitor<T, A> visitor, A argument) {
return visitor.visit(this, argument);
}
The visitor logic can the be invoked as follows:
difference.accept(new MyVisitor(), anOptionalArgument);
T determines the result type,
A determines the type of the optional argument
