Members
| Member | Description |
|---|---|
| NotApplicable | No merge action applies because there is no data source data. This merge strategy must be used – and may only be used – with the CacheOnly fetch strategy. |
| OverwriteChanges | Overwrites the cached entity with incoming data and uses the EntityState of the incoming entity (will be Unchanged if the incoming entity is from the data source). |
| PreserveChanges | Preserves (does not overwrite) any existing entities that have been changed (modified, added or deleted). |
| PreserveChangesUnlessOriginalObsolete | Preserves the persistent state of the cached entity if the entity is current. Overwrites an entity if it is obsolete and gives it the EntityState of the incoming entity (will be Unchanged if the incoming entity is from the data source). |
| PreserveChangesUpdateOriginal | Preserves the persistent state of the cached entity whether it is current or not. Overwrites the Original version of the entity if obsolete. |
