ManagedObject […]
represents a managed object.
Details
- ManagedObject is returned by functions such as CreateManagedObject .
- Only active managed objects evaluate the freeing function when they are no longer referenced.
- Managed objects can be inactivated with UnmanageObject .
- Information for a ManagedObject may include the following properties:
-
"Active" True if the object is actively being managed"BaseValue" the base value"FreeingFunction" the freeing function"Value" the value
- Properties can be accessed with ManagedObject […][prop].
- Properties that can be extracted include all Information properties listed above.
- Many functions that expect pointer objects will automatically unwrap managed expressions containing pointers.
