Keterangan
ComplexObject mengimplementasikan fungsionalitas dasar untuk jenis kompleks. Untuk informasi selengkapnya, lihat Objek Jenis Kompleks.
Saat menerapkan kelas data kustom dengan model konseptual, sebaiknya kelas data Anda yang mewakili jenis kompleks yang diwarisi dari ComplexObject. Untuk informasi selengkapnya, lihat Menyesuaikan Objek.
Jenis kompleks dapat menjadi properti dari jenis entitas atau jenis kompleks lainnya.
Jenis kompleks dikembalikan oleh properti non-skalar dari jenis entitas. Ini memungkinkan properti skalar diatur dalam entitas. Seperti entitas, jenis kompleks terdiri dari properti skalar atau properti jenis kompleks lainnya. Jenis kompleks tidak dapat digunakan tanpa jenis entitas terkait. Karena jenis kompleks tidak memiliki kunci, objek jenis kompleks tidak dapat dikelola tanpa jenis entitas terkait. Untuk informasi selengkapnya, lihat Objek Jenis Kompleks.
Konstruktor
| ComplexObject() |
Membuat instans ComplexObject. |
Metode
| Equals(Object) |
Menentukan apakah objek yang ditentukan sama dengan objek saat ini. (Diperoleh dari Object) |
| GetHashCode() |
Berfungsi sebagai fungsi hash default. (Diperoleh dari Object) |
| GetType() |
Mendapatkan dari instans Type saat ini. (Diperoleh dari Object) |
| GetValidValue<T>(T, String, Boolean, Boolean) |
Mengembalikan tipe kompleks untuk properti yang ditentukan. (Diperoleh dari StructuralObject) |
| MemberwiseClone() |
Membuat salinan dangkal dari saat ini Object. (Diperoleh dari Object) |
| OnPropertyChanged(String) |
Memunculkan kejadian PropertyChanged. (Diperoleh dari StructuralObject) |
| OnPropertyChanging(String) |
Memunculkan kejadian PropertyChanging. (Diperoleh dari StructuralObject) |
| ReportPropertyChanged(String) |
Memberi tahu pelacak perubahan bahwa properti objek kompleks telah berubah. |
| ReportPropertyChanging(String) |
Memberi tahu pelacak perubahan bahwa perubahan properti tertunda pada objek yang kompleks. |
| SetValidValue<T>(T, T, String) |
Mengatur objek kompleks untuk properti yang ditentukan. (Diperoleh dari StructuralObject) |
| ToString() |
Mengembalikan string yang mewakili objek saat ini. (Diperoleh dari Object) |
Acara
| PropertyChanged |
Terjadi ketika nilai properti telah berubah. (Diperoleh dari StructuralObject) |
| PropertyChanging |
Terjadi ketika perubahan nilai properti tertunda. (Diperoleh dari StructuralObject) |
