Is it possible to use opDispatch as generic getter and setter at the

this is what I've tried: https://gist.github.com/895571
and I get Error: template instance opDispatch!("bar") matches more
than one template declaration, path\to\test.d(57):opDispatch(string
entryName) and path\to\test.d(66):opDispatch(string entryName)
Is mixing @property with opDispatch supposed to work at all or is
opDispatch only ment for method calls?
Or maybe there is some other way to achive what I want and I'm not
aware of it? :-)
You can't have two methods named opDispatch like that. You can do
something like this:
class Foo {
@property ref ConfigSection opDispatch(string sectionName, Args
...)(Args args)
{
static if (Args.length == 0) {} // getter
else static if (Args.length == 1) { auto value = args[0]; } // setter
}
Or, I think this will work as well:
@property ref ConfigSection opDispatch(string sectionName, Args
...)(Args args) if (Args.length == 0)
{
// getter
}
@property ref ConfigSection opDispatch(string sectionName, Args
...)(Args args) if (Args.length == 1)
{
// setter
}
}
auto foo = new Foo;
foo.bar; // works
foo.bar = 3; // currently does not work, bug
foo.bar(3); // works
