Declares asynchronous methods for an object access layer.
| Name | Description |
|---|---|
| CommitChangesAsync(Session, ICollection, ICollection, CancellationToken) | Asynchronously commits object changes made in a specified session and notifies upon completion. |
| CreateObjectTypeAsync(XPObjectType, CancellationToken) | When implemented by a class, asynchronously creates an XPObjectType record. |
| GetObjectsByKeyAsync(Session, ObjectsByKeyQuery[], CancellationToken) | Retrieves object data from a session asynchronously, according to specified query parameters. |
| LoadCollectionObjectsAsync(Session, XPMemberInfo, Object, CancellationToken) | When implemented by a class, asynchronously loads a collection property using specified settings. |
| LoadDelayedPropertiesAsync(Session, IList, XPMemberInfo, CancellationToken) | Asynchronously loads data from a session to an object’s specific properties marked for delayed loading. |
| LoadDelayedPropertiesAsync(Session, Object, MemberPathCollection, CancellationToken) | Asynchronously loads data from a session to an object’s specific properties marked for delayed loading. |
| LoadObjectsAsync(Session, ObjectsQuery[], CancellationToken) | Loads persistent objects asynchronously, according to specified query parameters. |
| SelectDataAsync(Session, ObjectsQuery, CriteriaOperatorCollection, CriteriaOperatorCollection, CriteriaOperator, CancellationToken) | Retrieves object data from a session asynchronously, according to specified query parameters. |
| UpdateSchemaAsync(CancellationToken, Boolean, XPClassInfo[]) | When implemented by a class, asynchronously performs object layer specific operations that are required to update a data store’s schema according to the class descriptions of the specified types. |
