Enum member `std.traits.isInnerClass`

Determines whether T is a class nested inside another class and that T.outer is the implicit reference to the outer class (i.e. outer has not been used as a field or method name)


						
				enum isInnerClass(T)
				 = __traits(isSame, typeof(T.outer), __traits(parent, T)) && (staticIndexOf!(__traits(allMembers, T), "outer") == -1);

Parameters

Name	Description
T	type to test

Returns

true if T is a class nested inside another, with the conditions described above; false otherwise

Example

class C
{
    int outer;
}
static assert(!isInnerClass!C);

class Outer1
{
    class Inner1 { }
    class Inner2
    {
        int outer;
    }
}
static assert(isInnerClass!(Outer1.Inner1));
static assert(!isInnerClass!(Outer1.Inner2));

static class Outer2
{
    static class Inner
    {
        int outer;
    }
}
static assert(!isInnerClass!(Outer2.Inner));
