reflect.TrySend() Function in Golang with Examples Last Updated : 10 May, 2020 Comments Improve Suggest changes Like Article Like Report Go language provides inbuilt support implementation of run-time reflection and allowing a program to manipulate objects with arbitrary types with the help of reflect package. The reflect.TrySend() Function in Golang attempts to send x on the channel v but will not block. To access this function, one needs to imports the reflect package in the program. Syntax: func (v Value) TrySend(x Value) bool Parameters: This function accept one parameter of Value type (x). Return Value: This function returns whether the value was sent. Below examples illustrate the use of the above method in Golang: Example 1: C // Golang program to illustrate // reflect.TrySend() Function package main import ( "fmt" "reflect" ) func main() { c := make(chan int, 1) vc := reflect.ValueOf(c) // use of TrySend() method succeeded := vc.TrySend(reflect.ValueOf(123)) fmt.Println(succeeded, vc.Len(), vc.Cap()) } Output: true 1 1 Example 2: C // Golang program to illustrate // reflect.TrySend() Function package main import ( "fmt" "reflect" ) func main() { c := make(chan int, 1) vc := reflect.ValueOf(c) // use of TrySend() method succeeded := vc.TrySend(reflect.ValueOf(123)) fmt.Println(succeeded, vc.Len(), vc.Cap()) vSend, vZero := reflect.ValueOf(789), reflect.Value{} branches := []reflect.SelectCase{ {Dir: reflect.SelectDefault, Chan: vZero, Send: vZero}, {Dir: reflect.SelectRecv, Chan: vc, Send: vZero}, {Dir: reflect.SelectSend, Chan: vc, Send: vSend}, } selIndex, vRecv, sentBeforeClosed := reflect.Select(branches) fmt.Println(selIndex) fmt.Println(sentBeforeClosed) fmt.Println(vRecv.Int()) vc.Close() // Remove the send case branch this time, // for it may cause panic. selIndex, _, sentBeforeClosed = reflect.Select(branches[:2]) fmt.Println(selIndex, sentBeforeClosed) } Output: true 1 1 1 true 123 1 false Comment More infoAdvertise with us Next Article reflect.TrySend() Function in Golang with Examples S SHUBHAMSINGH10 Follow Improve Article Tags : Go Language Golang-reflect Similar Reads reflect.Type() Function in Golang with Examples Go language provides inbuilt support implementation of run-time reflection and allowing a program to manipulate objects with arbitrary types with the help of reflect package.
