Dependency calculation flags to control what is returned, and how it operates.
| RecursiveOperation | Depencency calculation is recursive. For each new valid reference discovered during calculation, the dependencies of those references will also be included in the returned results. |
| MissingReferences | Object dependencies returned for only missing references. |
| ValidReferences | Depencency calculation is not recursive. Only dependencies of the initial passed in set will be returned. |
| DefaultDependencies | Default mode. Dependencies are calculated recursively, and only valid references are returned. |
