Examples of org.objectweb.asm.ClassReader.accept()

org.objectweb.asm.ClassReader.accept()
Makes the given visitor visit the Java class of this {@link ClassReader ClassReader}. This class is the one specified in the constructor (see {@link #ClassReader(byte[]) ClassReader}). @param classVisitor the visitor that must visit this class. @param skipDebug true if the debug information of the class mustnot be visited. In this case the {@link CodeVisitor#visitLocalVariable visitLocalVariable} and {@link CodeVisitor#visitLineNumber visitLineNumber} methods will not be called.

    className = className.substring(className.lastIndexOf('.') + 1) + ".class";
        
    //Load the class bytes and copy methods across
    ClassReader cReader = new ClassReader(c.getResourceAsStream(className));


    cReader.accept(adapter, ClassReader.SKIP_CODE | 
        ClassReader.SKIP_DEBUG | ClassReader.SKIP_FRAMES);
