Examples of alt.jiapi.reflect.JiapiClass.addMethod()

alt.jiapi.reflect.JiapiClass.addMethod()
Adds a new method to this class. The signature is derived from given methods signature. @param m JiapiMethod to be used as method signature @return JiapiMethod which was added @exception MethodExistsException if a method with a same name andparameter signature already exists

    static byte[] jiapiHelloWorld() throws MethodExistsException {
        JiapiClass c = JiapiClass.createClass("HelloWorld");


        // No API to set SourceFile!


        JiapiMethod method = c.addMethod(Modifier.PUBLIC, "<init>", emptySig);
        InstructionList il = method.getInstructionList();
        InstructionFactory iFactory = il.getInstructionFactory();
        il.add(iFactory.aload(0));
        il.add(iFactory.invoke(0, "java/lang/Object", "<init>", emptySig));
        il.add(iFactory.returnMethod(method));
