reflect.ChanOf() 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. The reflect.ChanOf() Function in Golang is used to get the channel type with the given direction and element type, i.e., t represents int, ChanOf(RecvDir, t) represents <-chan int. To access this function, one needs to imports the reflect package in the program.

Syntax:

func ChanOf(dir ChanDir, t Type) Type

Parameters: This function takes three parameters of ChanDir type (dir ) and Type type(t).

Return Value: This function returns the function type with the given direction and element type.

Below examples illustrate the use of above method in Golang:

code

// Golang program to illustrate
// reflect.ChanOf() Function 
  
package main
  
import (
    "fmt"
    "reflect"
)
  
// Main function 
func main() {
  
    var k = reflect.TypeOf(0)
      
    // use of ChanOf method
    fmt.Println( reflect.ChanOf(reflect.SendDir, k))
}
