[SOLVED]How to check the input Object Type?

Hello,

-I have two output ports which contents "obj1 (obj1.class), obj2 (obj2.class)" for each as the release object.
-I have one input prot.
-What I want is checking the input object type when I get the Data form whatever which output port released.

obj1(output) \
                    ------- input port  
obj2(output) /

I thought I can do like:

 if(input.getData() instancof Obj1)
    do ....

But the "getData()" method was deprecated

I have to use "input.get(Obj1.class)" or"input.get(Obj2.class)"

If I do so, I think the way what I just proposed won't be work.

Could you help me?

Thanks
