* Removed unused code
* Use cclog for logging
* Wrap errors so that they can be unwrapped
* Revert wrong use of slices.Delete()
* Fix derivative values should be float
* Suggestions from the gocritic linter
* Fixed: interface method AddChannel must have all named params (inamedparam)
* Enable linter: errorlint
* Replace fmt.Sprintf("%d", i)) by strconv.Itoa(i) for improved performance
* Correct misspelled words
* Break up very long lines into multiple lines
* lp.NewMessage -> lp.NewMetric
* Preallocate slices of known length
MultiChanTicker
The idea of this ticker is to multiply the output channels. The original Golang time.Ticker provides only a single output channel, so the signal can only be received by a single other class. This ticker allows to add multiple channels which get all notified about the time tick.
type MultiChanTicker interface {
Init(duration time.Duration)
AddChannel(chan time.Time)
}
The MultiChanTicker is created similarly to the common time.Ticker:
NewTicker(duration time.Duration) MultiChanTicker
Afterwards, you can add channels:
t := MultiChanTicker(duration)
c1 := make(chan time.Time)
c2 := make(chan time.Time)
t.AddChannel(c1)
t.AddChannel(c2)
for {
select {
case t1 := <- c1:
log.Print(t1)
case t2 := <- c2:
log.Print(t2)
}
}
The result should be the same time.Time output in both channels, notified "simultaneously".
