I discovered a neat property of Swift: Anywhere I can pass a closure, I can
also pass a object method (of matching type), and if I reference it from an
instance, it captures that instance for the call:
class
Foo
{
func actOnFoo(inValue: Int)
{
}
}
func
neato()
{
var foo: Foo = Foo();
doSomething(foo.actOnFoo);
}
func
doSomething(inFunc: (Int) -> ())
{
}
Inside doSomething(), is it possible to get at inFunc's "self" (in this case,
it would be foo)?
