# 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.
|
||
|
|
||
|
```golang
|
||
|
type MultiChanTicker interface {
|
||
|
Init(duration time.Duration)
|
||
|
AddChannel(chan time.Time)
|
||
|
}
|
||
|
```
|
||
|
|
||
|
The MultiChanTicker is created similarly to the common `time.Ticker`:
|
||
|
|
||
|
```golang
|
||
|
NewTicker(duration time.Duration) MultiChanTicker
|
||
|
```
|
||
|
|
||
|
Afterwards, you can add channels:
|
||
|
|
||
|
```golang
|
||
|
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".
