IRecordDeclarationHandler-Schnittstelle
Stellt eine Schnittstelle für die weitere Verarbeitung ein Element als Datensatz deklariert.
Namespace: Microsoft.Office.RecordsManagement.RecordsRepository
Assembly: Microsoft.Office.Policy (in Microsoft.Office.Policy.dll)
Syntax

Public Interface IRecordDeclarationHandler
'Usage
Dim instance As IRecordDeclarationHandler

Hinweise
Wenn ein Element als Datensatz deklariert wird, kann benutzerdefinierte Verarbeitung Handler hinzugefügt werden, durch die OnDeclare-Methode in der IRecordDeclarationHandler-Schnittstelle implementieren. Nachdem der Handler das Listenelement verarbeitet hat, können sie fortzufahren, oder fahren Sie Standardverarbeitung durch Rückgabe der Corresponiding RecordOperationResult.
Die folgenden Codebeispiele zeigen einen benutzerdefinierte Handler registrieren und erstellen Sie einen benutzerdefinierte Deklaration Filter, der Datensatzdeklaration und Undeclaration verwaltet.
