getValueDependencies(obj)

Return the observable objects that provide input values to generate the computed value of the Value-like object obj. If obj does not have dependencies, returns undefined. Otherwise returns an object with up to two keys: keyDependencies is a CIDMap that maps each Map-like object providing keyed values to an Array of the relevant keys; valueDependencies is a CIDSet that contains all Value-like dependencies providing their own values.

obj must implement @@can.getValueDependencies to work with canReflect.getValueDependencies.

var foo = new DefineMap({ "bar": "baz" })
var obj = canCompute(function() {
     return foo.bar;
});

canReflect.getValueDependencies(obj);  // -> { valueDependencies: CIDSet } because `obj` is internally backed by
