reflect.Type() Function in Golang with Examples
Last Updated :

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.Type() Function in Golang is used to get v’s type. To access this function, one needs to imports the reflect package in the program.
Syntax:
func (v Value) Type() Type
Parameters: This function does not accept any parameter.
Return Value: This function returns the v’s type.
Below examples illustrate the use of above method in Golang:
Example 1:
package main
import (
"fmt"
"reflect"
)
func main() {
var val chan int
value := reflect.MakeChan(reflect.Indirect(reflect.ValueOf(&val)).Type(), 0)
fmt.Println( "Value :" , value)
}
|
Output:
Value : 0xc00010c000
Example 2:
package main
import (
"fmt"
"reflect"
)
func main() {
var str map[ int ]string
var strValue reflect.Value = reflect.ValueOf(&str)
indirectStr := reflect.Indirect(strValue)
valueMap := reflect.MakeMap(indirectStr.Type())
fmt.Printf( "ValueMap is [%v] ." , valueMap)
}
|
Output:
ValueMap is [map[]] .
