l0.DependencyControl.Timer

Timer = require "l0.DependencyControl.Timer"

local Timer = require("l0.DependencyControl.Timer")

Timer

Timer with monotonic clock readings and millisecond sleep. Not affected by system clock changes.

Constructor 

timer = Timer!

local timer = Timer()

Creates a new timer, running from the current time.

Instance methods

start 

timer\start!

timer:start()

Resumes measurement from the current time. No-op if already running, so a prior stop/start round trip never discards accumulated time.

Returns:

  • self Timer — for chaining

stop 

timer\stop!

timer:stop()

Pauses measurement, folding the elapsed interval into the accumulated total. No-op if already stopped.

Returns:

  • self Timer — for chaining

reset 

timer\reset!

timer:reset()

Clears the accumulated time and restarts measuring from the current time, preserving the running/stopped state.

Returns:

  • self Timer — for chaining

Class methods

sleep 

Timer.sleep ms

Timer.sleep(ms)

Sleeps for the given number of milliseconds.

param type description
ms number

getTime 

Timer.getTime!

Timer.getTime()

Returns the current value of the process's monotonic clock, in milliseconds, at sub-millisecond resolution. Only differences between readings are meaningful.

Returns:

  • milliseconds number

Fields

field type description
elapsed number Milliseconds measured so far, excluding any intervals during which the timer was stopped. Read-only.
