var OutputStreamCallback = Java.type("org.apache.nifi.processor.io.OutputStreamCallback");
var StandardCharsets = Java.type("java.nio.charset.StandardCharsets");

Date.prototype.isValid = function ()
{
    return (Object.prototype.toString.call(this) === "[object Date]") && !isNaN(this.getTime());
};


var flowFile=session.get()
if (flowFile != null) {
    var userId = flowFile.getAttribute('userId')
    var parameter = flowFile.getAttribute('parameter')
    var i = 0;

    for(i=0;i<=parameter;i++) {
        var flowfile1=session.create();

        userId++;
        flowfile1 = session.putAttribute(flowfile1, 'filename', userId);


        flowfile1 = session.write(flowfile1,
            new OutputStreamCallback(function (outputStream) {
                outputStream.write(0)
            }));



        session.transfer(flowfile1, REL_SUCCESS)

        parameter--;
    }

    session.remove(flowFile)
}
