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 Interface can be used without panicking. To access this function, one needs to imports the reflect package in the program.
Syntax:
func (v Value) CanInterface() boolParameters: 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:
// Golang program to illustrate // reflect.CanInterface() Function package main import ( "fmt"
"reflect"
) // Main function func main() { num := 6
meta := reflect.ValueOf(num)
// use of CanInterface() method
fmt.Println( "canInterface:" , meta.CanInterface() == true )
} |
Output:
canInterface: true
Example 2:
// Golang program to illustrate // reflect.CanInterface() Function package main import ( "fmt"
"reflect"
) // Main function func main() { string := "ABC"
meta := reflect.ValueOf(&string)
// use of CanInterface() method
fmt.Println( "canInterface:" , meta.CanInterface() == false )
} |
Output:
canInterface: false
