Virtual Infrastructure Extensible Managed Object APIs

ExtensibleManagedObject provides methods and properties that provide access to custom fields that may be associated with a managed object.

Use the CustomFieldsManager to define custom fields. The CustomFieldsManager handles the entire list of custom fields on a server. You can can specify the object type to which a particular custom field applies by setting its managedObjectType. (If you do not set a managed object type for a custom field definition, the field applies to all managed objects.)
