InstanceAvailability Enumeration (original) (raw)
Summary
The availability of the referenced Instance
Syntax
public enum InstanceAvailability public enum class InstanceAvailability : public System.Enum, System.IComparable, System.IConvertible, System.IFormattable Members
| Value | Member | Description |
|---|---|---|
| 0 | NotProvided | Value not provided. |
| 1 | Online | Instances are immediately available from the Retrieve AE Title (0008,0054), and if a C-MOVE were to be requested, it would succeed in a reasonably short time. |
| 2 | Nearline | Instances need to be retrieved from relatively slow media such as optical disk or tape. If a C-MOVE were to be requested from the Retrieve AE Title (0008,0054), it would succeed, but may take a considerable time' |
| 3 | Offline | A manual intervention is needed before the instances may be retrieved. If a C-MOVE were to be requested from the Retrieve AE Title (0008,0054), it would fail (e.g., by timeout) without such manual intervention. |
| 4 | Unavailable | Instances cannot be retrieved from the Retrieve AE Title (0008,0054). If a C-MOVE were to be requested, it would fail. Note that SOP Instances that are unavailable from this AE may be available from other AEs, or may have an alternate representation that is available from this AE. |
