Class 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 appropriate 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.

        Returns:
        Class object representing the parsed class file
        Throws:
        IOException - If an I/O occurs reading the byte code
        ClassFormatException - If the byte code is invalid
