Casting class types
Casting to a class type T from a value can be achieved with the following:
cast(T) value
Casting will result in a null reference when the cast cannot be made. (There is no instanceof operator, because it is not needed.)
MyType castedValue = cast(MyType) someValue;
if (castedValue !is null)
{
/* use the casted value */
}
