Pass method as parameter Groovy

I am creating a Groovy project and I would like to pass a method as a parameter is this possible?

I have 2 methods, which basically do the same thing but have a few small differences, each have different properties.

I would like to send through whether to use the 'buildPayLoad' function or 'buildSecondPayLoad' into my sendEmail function. 

    private Operation sendEmail(Order order) {
                  def payload = buildPayload(order, templateId)
    }


    private firstEmailPayLoad buildPayload(Order order, String templateId) {
            new firstEmailPayLoad(
                templateId,
                config.fromAddress,
                order.firstPayLoadProperty,
                buildEmailDataFirstPayLoad(order)
            ).validate()
   }

   private secondEmailPayLoad buildSecondPayLoad(Order order, String templateId) {
            new secondEmailPayLoad(
                templateId,
                config.fromAddress,
                config.bccAddress,
                config.otherProperty,
                order.secondPayLoadProperty
                buildEmailData(order)
            ).validate()
 }

You can just do:

private Operation sendEmail(Order order, Closure builder) {
    def payload = builder(order, templateId)
}

Then call it with:

sendEmail(order, this.&buildPayload)

Or

sendEmail(order, this.&buildSecondPayLoad)

BTW: You really should start class names with a capital letter, so instead of secondEmailPayLoad, you should call it SecondEmailPayLoad (and the same with firstEmailPayLoad)
