Timer Observable

Rocket.timerFunction
timer(due_time::Int = 0, period = nothing)

Creation operator for the TimerObservable. Its like interval(@ref), but you can specify when should the emissions start. timer returns an Observable that emits an infinite sequence of ascending integers, with a constant interval of time, period of your choosing between those emissions. The first emission happens after the specified due_time. If period is not specified, the output Observable emits only one value, 0. Otherwise, it emits an infinite sequence.

Arguments

  • due_time: the initial delay time specified as an integer denoting milliseconds to wait before emitting the first value of 0.
  • period: the period of time between emissions of the subsequent numbers.

Examples

using Rocket

source = timer(0, 50)

sleep(0.075)
subscription = subscribe!(source, logger())
sleep(0.105)
unsubscribe!(subscription)

close(source)
;

# output

[LogActor] Data: 2
[LogActor] Data: 3

Rocket.TimerObservableType
TimerObservable(due_time::Int, period::Union{Int, Nothing} = nothing)

An Observable that starts emitting after an dueTime and emits ever increasing numbers after each period of time thereafter.

Fields

  • due_time: The initial delay time specified as an integer denoting milliseconds to wait before emitting the first value of 0`.
  • period: The period of time in milliseconds between emissions of the subsequent numbers.
