baseInterface

Deduces single base interface for a type. Multiple interfaces will result in compile-time error.

template baseInterface (

T

) if (

is(T == interface) ||

is(T == class)

) {

import std.traits : InterfacesTuple;;

alias baseInterface = T;

alias Ifaces = InterfacesTuple!T;

alias baseInterface = Ifaces[0];

}

Ifaces alias Ifaces = InterfacesTuple!T: Undocumented in source.
baseInterface alias baseInterface = T: Undocumented in source.
baseInterface alias baseInterface = Ifaces[0]: Undocumented in source.

Parameters

T: interface or class type

Return Value

T if it is an interface. If T is a class, interface it implements.

Examples

interface I1 { }
class A : I1 { }
interface I2 { }
class B : I1, I2 { }

static assert (is(baseInterface!I1 == I1));
static assert (is(baseInterface!A == I1));
static assert (!is(typeof(baseInterface!B)));
