StringRepresentation

public class StringRepresentation extends EmptyVisitor implements 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.

Fields Summary
private String
tostring
The string representation, created by a visitXXX() method, output by toString().
Constructors Summary
public StringRepresentation(Node n)
Creates a new StringRepresentation object which is the representation of n.

see
#toString()

		n.accept(this);
Methods Summary
public java.lang.StringtoString()
Returns the String representation.

		return tostring;
private java.lang.StringtoString(com.sun.org.apache.bcel.internal.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.

		String ret;
		try{
			ret = obj.toString();
		}
		catch(RuntimeException e){
			String s = obj.getClass().getName();
			s = s.substring(s.lastIndexOf(".")+1);
			ret = "<<"+s+">>";
		}
		return ret;
