reflect.SliceOf() Function in Golang with Examples

  • Last Updated : 28 Apr, 2020

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.SliceOf() Function in Golang is used to get the slice type with element type t, i.e., if t represents int, SliceOf(t) represents []int. To access this function, one needs to imports the reflect package in the program.

Syntax:

func SliceOf(t Type) Type

Parameters: This function takes only one parameters of Type type(t).

Return Value: This function returns the slice type with element type t.

Below examples illustrate the use of above method in Golang:



Example 1:




// Golang program to illustrate
// reflect.SliceOf() Function 
   
package main
   
import (
    "fmt"
    "reflect"
       
)
   
// Main function 
func main() {
   
    v := reflect.TypeOf("123")
       
    // use of SliceOfmethod
    fmt.Println(reflect.SliceOf(v))
   
}

Output:

[]string

Example 2:




// Golang program to illustrate
// reflect.SliceOf() Function 
  
package main
  
import (
    "fmt"
    "reflect"
      
)
  
// Main function 
func main() {
  
    ta := reflect.ArrayOf( 10, reflect.TypeOf("123"))
      
    tc := reflect.ChanOf(reflect.SendDir, ta)
      
    tp := reflect.PtrTo(tc)
      
    ts := reflect.SliceOf(tp)
      
    // use of SliceOf method
    fmt.Println(ts)
  
}

Output:

[]*chan<- [10]string
