Constant

Inputs: i1
Outputs: o1

Emits the same value regardless the time field of the message received on i1.

The Constant operator does not hold a message buffer on i1, so it emits a message with a constant value field through o1 right after it receives a message on i1.

$y(t_n)=C$.

Parameters

id: The id of the operator

value: The constant to emit when required.

Usage

TypeScript

import { Program, Constant } from "@rtbot-dev/rtbot";

const id = "id";
const value = 3.14;

const program = new Program();
program.addOperator(new Constant(id, value));

Python

import rtbot as rb

id = "id";
value = 3.14;

program = rb.Program()
program.addOperator(rb.Constant(id, value))

C++

#include "rtbot/Constant.h"

auto id = "id";
auto value = 3.14;

auto op = Constant<std::uint64_t, double>(id, value)

YAML

# minimal RtBot program
operators:
  - type: Constant
    id: "id"
    value: 3.14

Json

  "operators": [
    { "type": "Constant", "id": "id", "value": 3.14 }
