It is boring coding, I want a solution to copy them
automatically:
void copyObj(SRC,DEST)(SRC src,DEST dest)
{
foreach (i, type; typeof(SRC.tupleof)) {
auto name = SRC.tupleof[i].stringof;
__traits(getMember, dest, name) = __traits(getMember, src,
name);
writeln(name);
}
}
Unfortunitely, it doesnt work, how to improve it?
Assuming that the hibernated class isn't auto-generated and you
can redefine its contents freely, the following style may be an
alternative that works for you:
struct Foo {
public:
string a;
int b;
}
class FooClass {
public:
union {
struct {
string a;
int b;
};
Foo foo;
}
}
void main() {
Foo f = Foo("a", 10);
FooClass c = new FooClass();
c.foo = f;
writefln("%s %s", c.a, c.b);
}
Probably the anonymous struct will break the UDAs, but it should
be worth testing.
