So, what I'm trying to accomplish is a little unusual, and may need some
explanation.
Basically, I'm trying to find a typesafe way to access a type-indexed map of
components. This map can contain objects of any type, and the keys are
reflect.Type.
One strategy I thought may work would be to pass a pointer to a pointer as an
out-var. Using reflection to determine the pointer's type, it could be
populated with a corresponding value.
For instance, if we did something like this:
c := ComponentCollection{}
c.addComponent(123) // Add an int component
var p : *int
c.getComponent(&p)
In this case, p would point to the int component of c.
That's wht the 2 levels of indirection are necessary: it's an out-var to a
pointer.
Does that make sense?
