I have a function written in Golang as follows
func (participant *SimulationParticipant) StartTransactionsGatewayTicker() {
//Gateway
logging.InfoLogger.Printf("StartTransactionsGatewayTicker:%v", participant.Participant)
ticker := time.NewTicker(1 * time.Second)
participant.TransactionGatewayTicker = ticker
go func() {
for {
select {
case <-ticker.C:
logging.InfoLogger.Printf("Tick at: %v", participant.Participant)
participant.GetTransactions()
}
}
}()
}
I am calling the function in a loop as with 2 SimulationParticipant in the array. surprisingly the first participant is replaced by second participant and the GetTransactions always getting executed to the last item in the loop? How can I overcome this
Works for me (I am posting this code without seeing how you are calling StartTransactionsGatewayTicker, Donot downvote if not applicable :P ) :
// [Timers](timers) are for when you want to do
// something once in the future - _tickers_ are for when
// you want to do something repeatedly at regular
// intervals. Here's an example of a ticker that ticks
// periodically until we stop it.
package main
import (
"fmt"
"time"
)
func main() {
part1 := SimulationParticipant{}
part1.id = "part1"
part2 := SimulationParticipant{}
part2.id = "part2"
partSlice := make([]*SimulationParticipant,0)
partSlice = append(partSlice, &part1, &part2)
for _ , p := range partSlice {
p.StartTransactionsGatewayTicker()
}
// Tickers can be stopped like timers. Once a ticker
// is stopped it won't receive any more values on its
// channel. We'll stop ours after 16000ms.
time.Sleep(16000 * time.Millisecond)
part1.ticker.Stop()
part2.ticker.Stop()
fmt.Println("Ticker stopped")
}
type SimulationParticipant struct {
id string
ticker *time.Ticker
}
func (participant *SimulationParticipant) StartTransactionsGatewayTicker() {
ticker := time.NewTicker(1 * time.Second)
participant.ticker = ticker
go func() {
for {
select {
case t := <-ticker.C:
fmt.Println("Tick at", t,participant.id)
}
}
}()
}
