Class ClassReader

java.lang.Object
  java.io.InputStream
      java.io.ByteArrayInputStream
          at.davinci.util.ClassReader

All Implemented Interfaces:

java.io.Closeable

Direct Known Subclasses:

ParamReader

public class ClassReader
extends java.io.ByteArrayInputStream

This is the class file reader for obtaining the parameter names for declared methods in a class. The class must have debugging attributes for us to obtain this information.

This does not work for inherited methods. To obtain parameter names for inherited methods, you must use a paramReader for the class that originally declared the method.

don't get tricky, it's the bare minimum. Instances of this class are not threadsafe -- don't share them.
