Hinweise
ComplexObject implementiert die grundlegende Funktionalität für komplexe Typen. Weitere Informationen finden Sie unter Komplexe Typobjekte.
Beim Implementieren benutzerdefinierter Datenklassen mit einem konzeptionellen Modell wird empfohlen, dass Ihre Datenklassen, die komplexe Typen darstellen, von ComplexObjecterben. Weitere Informationen finden Sie unter Anpassen von Objekten.
Ein komplexer Typ kann eine Eigenschaft eines Entitätstyps oder eines anderen komplexen Typs sein.
Komplexe Typen werden von nicht skalaren Eigenschaften von Entitätstypen zurückgegeben. Damit können skalare Eigenschaften innerhalb der Entitäten organisiert werden. Wie Entitäten bestehen komplexe Typen aus skalaren Eigenschaften oder anderen Eigenschaften von komplexem Typ. Ein komplexer Typ kann nicht ohne einen zugeordneten Entitätstyp verwendet werden. Da komplexe Typen über keine Schlüssel verfügen, können komplexe Typobjekte ohne einen zugeordneten Entitätstyp nicht verwaltet werden. Weitere Informationen finden Sie unter Komplexe Typobjekte.
Konstruktoren
| ComplexObject() |
Erstellt eine Instanz von ComplexObject. |
Methoden
| Equals(Object) |
Bestimmt, ob das angegebene Objekt gleich dem aktuellen Objekt ist. (Geerbt von Object) |
| GetHashCode() |
Fungiert als Standardhashfunktion. (Geerbt von Object) |
| GetType() |
Ruft den Type der aktuellen Instanz ab. (Geerbt von Object) |
| GetValidValue<T>(T, String, Boolean, Boolean) |
Gibt einen komplexen Typ für die angegebene Eigenschaft zurück. (Geerbt von StructuralObject) |
| MemberwiseClone() |
Erstellt eine flache Kopie des aktuellen Object. (Geerbt von Object) |
| OnPropertyChanged(String) |
Löst das PropertyChanged-Ereignis aus. (Geerbt von StructuralObject) |
| OnPropertyChanging(String) |
Löst das PropertyChanging-Ereignis aus. (Geerbt von StructuralObject) |
| ReportPropertyChanged(String) |
Benachrichtigt den Änderungsprotokollierer über die Änderung einer Eigenschaft eines komplexen Objekts. |
| ReportPropertyChanging(String) |
Benachrichtigt den Änderungsprotokollierer über die ausstehende Änderung einer Eigenschaft eines komplexen Objekts. |
| SetValidValue<T>(T, T, String) |
Legt ein komplexes Objekt für die angegebene Eigenschaft fest. (Geerbt von StructuralObject) |
| ToString() |
Gibt eine Zeichenfolge zurück, die das aktuelle Objekt darstellt. (Geerbt von Object) |
Ereignisse
| PropertyChanged |
Tritt auf, wenn sich ein Eigenschaftswert geändert hat. (Geerbt von StructuralObject) |
| PropertyChanging |
Tritt auf, wenn die Änderung eines Eigenschaftswerts aussteht. (Geerbt von StructuralObject) |
