LessThanStream

Inputs: i1 i2
Outputs: o1

Synchronizes two streams (given by i1 and i2) and emits the message in i1 if its value is less than the value of i2 for the synchronized $t_n$.

The synchronization mechanism is inherited from the Join operator. The LessThanStream operator holds a message buffer on i1 and i2 respectively, after synchronization occurs it emits the message in i1 through o1 if it happens to be less than the message value in i2 and it discard the message in i2, if no synchronization occurs then an empty message {} is emitted through o1.

$y(t_n) = x_1(t_n) if x_1(t_n) < x_2(t_n)$

Parameters

id: The id of the operator

Usage

TypeScript

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

const id = "id";

const program = new Program();
program.addOperator(new LessThanStream(id));

Python

import rtbot as rb

id = "id";

program = rb.Program()
program.addOperator(rb.LessThanStream(id))

C++

#include "rtbot/LessThanStream.h"

auto id = "id";

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

YAML

# minimal RtBot program
operators:
  - type: LessThanStream
    id: "id"
