How to incapsulate data in IOContainer

Hi i have extract a model file from a process.
I want load the model and apply this model to data that i calculate a runtime.
The data are all integer value.
My code is

        RapidMiner.init();
    //create the operator for apply model
      Operator testSource = OperatorService.createOperator(ModelApplier.class);
        //create the operator for load the model
      Operator loadModel= OperatorService.createOperator(ModelLoader.class);

then i have to load the model and this is not a problem.
My problem is
" How i can incapsulate a set of number in an IOContainer for using this as input of the Model?"

Thank you very much
