Class PreorderVisitor

java.lang.Object
edu.umd.cs.findbugs.visitclass.BetterVisitor
edu.umd.cs.findbugs.visitclass.PreorderVisitor
All Implemented Interfaces:
org.apache.bcel.classfile.Visitor
Direct Known Subclasses:

public class PreorderVisitor extends BetterVisitor

Interface to make the use of a visitor pattern programming style possible. I.e. a class that implements this interface can traverse the contents of a Java class just by calling the `accept' method which all classes have.

Implemented by wish of Boris Bokowski.
