Class ClassParser


  • public final class ClassParser
    extends java.lang.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.

        public JavaClass parse()
                        throws java.io.IOException,
                               ClassFormatException
        Parses the given Java class file and return an object that represents the contained data, i.e., constants, methods, fields and commands. A ClassFormatException is raised, if the file is not a valid .class file. (This does not include verification of the byte code as it is performed by the java interpreter).
        Returns:
        Class object representing the parsed class file
        Throws:
        java.io.IOException - If an I/O occurs reading the byte code
        ClassFormatException - If the byte code is invalid
