reflect.CanAddr() Function in Golang with Examples Last Updated : 03 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.CanAddr() Function in Golang is used to check whether the value's address can be obtained with Addr. To access this function, one needs to imports the reflect package in the program. Syntax: func (v Value) CanAddr() bool Parameters: This function does not accept any parameters. Return Value: This function returns the boolean value. Below examples illustrate the use of the above method in Golang: Example 1: C // Golang program to illustrate // reflect.CanAddr() Function package main import ( "fmt" "reflect" ) // Main function func main() { typ := reflect.StructOf([]reflect.StructField{ { Name: "Height", Type: reflect.TypeOf(float64(0)), Tag: `json:"height"`, }, { Name: "Age", Type: reflect.TypeOf(int(0)), Tag: `json:"age"`, }, }) v := reflect.New(typ).Elem() v.Field(0).SetFloat(0.4) v.Field(1).SetInt(2) s := v.CanAddr() fmt.Printf("value: %+v\n", s) } Output: value: true Example 2: C // Golang program to illustrate // reflect.CanAddr() Function package main import ( "fmt" "reflect" ) // Main function type superint struct { A int B int } func (s *superint) lol() {} type a interface{ lol() } func main() { i := superint{A: 1, B: 9} valPtr := reflect.ValueOf(&i) fmt.Printf("%v \n", i) // use of Addr() method fmt.Printf("%v \n", valPtr.Elem().CanAddr()) } Output: {1 9} true Comment More infoAdvertise with us Next Article reflect.CanAddr() Function in Golang with Examples S SHUBHAMSINGH10 Follow Improve Article Tags : Go Language Golang-reflect Similar Reads reflect.Addr() 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.
