- java.lang.Object
- - org.apache.tomcat.util.bcel.classfile.ClassParser

-     public final class ClassParser
      extends Object

  Wrapper class that parses a given Java .class file. The method parse returns a JavaClass object on success.

The structure and the names comply, except for a few conveniences, exactly with the JVM specification 1.0. See this paper for further details about the structure of a bytecode file.
