As a user (read developer), I'd rather code to the generic interface
when possible. I like that concrete implementations looks rather long
and ugly
I don't think you should be worried that your users is using direct
implementations rather than the interface - their problem!
Remember that in D, interfaces can contain implementations that only
uses static methods on the interface:
interface DB {
@property string name();
// interfaces can have implementations
static DB createDefault() { return new GenericDB(); }
}
class GenericDB : DB {
@property string name() {
return "generic"; }
}
class MySQLDB : DB {
@property string name() {
return "mysql"; }
}
void main() {
assert(DB.createDefault().name == "generic");
assert((new MySQLDB()).name == "mysql");
}
I see what you are saying. If it is not possible to have a default I
think I will call the interface Database and the class BasicDatabase as
that sounds intuitive.
Thanks to everyone for the help.
