Hi,
Using interface is easy in Go. But, while studying an existing code base,
it is very difficult to find which types have implementation of a
particular interface. The situation will become worse, if there are many
interface functions inside an interface definition.
In another languages, it is easy to just search for the class, which
implements a particular interface.
For example in Java,
interface Animal {
public void eat();
public void travel();
}
public class MammalInt implements Animal {
public void eat() {
System.out.println("Mammal eats");
}
public void travel() {
System.out.println("Mammal travels");
}
public int noOfLegs() {
return 0;
}
public static void main(String args[]) {
MammalInt m = new MammalInt();
m.eat();
m.travel();
}
}
By seeing the above line "*public class MammalInt **implements Animal*" one
can easily understand that Animal interface is implemented in MammalInt
In Go, as far as I know, I need to search for all interface functions to
find whether a type implements a particular interface or not.
Have anybody else experienced the same? If yes, what is the solution?
*Note:* Personally I like to write code in Go; all of my recent projects
are in Go. I prefer Go than Java.
Sincerely,
Arafath M
