org.apache.bcel.verifier.statics
Class StringRepresentation  

java.lang.Object
  org.apache.bcel.classfile.EmptyVisitor
      org.apache.bcel.verifier.statics.StringRepresentation

All Implemented Interfaces:

org.apache.bcel.classfile.Visitor

public class StringRepresentation

extends org.apache.bcel.classfile.EmptyVisitor

implements org.apache.bcel.classfile.Visitor

BCEL's Node classes (those from the classfile API that accept() Visitor instances) have toString() methods that were not designed to be robust, this gap is closed by this class. When performing class file verification, it may be useful to output which entity (e.g. a Code instance) is not satisfying the verifier's constraints, but in this case it could be possible for the toString() method to throw a RuntimeException. A (new StringRepresentation(Node n)).toString() never throws any exception. Note that this class also serves as a placeholder for more sophisticated message handling in future versions of JustIce.

Field Summary
private  org.apache.bcel.classfile.Node	n           The node we ask for its string representation.
private  java.lang.String	tostring           The string representation, created by a visitXXX() method, output by toString().

 

Constructor Summary

StringRepresentation(org.apache.bcel.classfile.Node n)           Creates a new StringRepresentation object which is the representation of n.

 

Method Summary
java.lang.String	toString()           Returns the String representation.
private  java.lang.String	toString(org.apache.bcel.classfile.Node obj)           Returns the String representation of the Node object obj; this is obj.toString() if it does not throw any RuntimeException, or else it is a string derived only from obj's class name.
