Listing Method Names in an Interface Type Using Runtime Reflection
In Go, interfaces define contracts for method signatures. However, obtaining the names of methods within an interface at runtime can be challenging. This article addresses this issue, exploring a method to list the method names using reflection.
Problem:
Consider the following interface type:
<code class="go">type FooService interface { Foo1(x int) int Foo2(x string) string }</code>
The objective is to obtain a list of method names like ["Foo1", "Foo2"] dynamically using runtime reflection.
Solution:
To retrieve the method names, we can use the following steps:
Here's the code implementation:
<code class="go">t := reflect.TypeOf((*FooService)(nil)).Elem() var s []string for i := 0; i < t.NumMethod(); i++ { s = append(s, t.Method(i).Name) }</code>
By utilizing the provided solution, you can dynamically generate a list of method names for any given interface type in your Go programs.
