Passing in a type variable into function

Question

I\'m trying to achieve a type assertion by passing in a type into a function. In other words, I\'m trying to achieve something like this:

// Note that this i

@hlin117,

Hey, if I understood your question correctly and you need to compare the types, here's what you can do:

package main

import (
    "fmt"
    "reflect"
)

func myfunction(v interface{}, mytype interface{}) bool {
    return reflect.TypeOf(v) == reflect.TypeOf(mytype)
}

func main() {

    assertNoMatch := myfunction("hello world", map[string]string{})

    fmt.Printf("%+v\n", assertNoMatch)

    assertMatch := myfunction("hello world", "stringSample")

    fmt.Printf("%+v\n", assertMatch)

}

The approach is to use a sample of the type you'd like to match.
