Class ClassParser

java.lang.Object

org.aspectj.apache.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. When an I/O error or an inconsistency occurs an appropiate exception is propagated back to the caller. 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.
