Examples of serp.bytecode.Code.aload()

serp.bytecode.Code.aload()
Load an object local variable onto the stack. This instruction will result in a nop until its local index is set.

        code.aload().setParam(0);
        code.invokeinterface().setMethod(OpenJPAStateManager.class,
            "getVersion", Object.class, null);
        JumpInstruction ifins = code.ifnonnull();
        code.aload().setParam(0);
        code.aload().setThis();
        code.getfield().setField("version", Object.class);
        code.invokeinterface()
            .setMethod(OpenJPAStateManager.class, "setVersion",
                void.class, new Class[]{ Object.class });
        ifins.setTarget(code.vreturn());
