EFCoreObjectSpace.Contains(Object) Method

Indicates whether a specified object belongs to the current Object Space.

Namespace: DevExpress.ExpressApp.EFCore

Assembly: DevExpress.ExpressApp.EFCore.v25.2.dll

NuGet Package: DevExpress.ExpressApp.EFCore

Declaration

C#

public override bool Contains(
    object obj
)

VB.NET

Public Overrides Function Contains(
    obj As Object
) As Boolean

Parameters

Name	Type	Description
obj	Object	A persistent object this method checks.

Returns

Type	Description
Boolean	true if the specified persistent object belongs to the current Object Space; otherwise, false.

Remarks

Persistent objects that you process can belong to different Object Spaces. For instance, one object can be from a Detail View’s Object Space, another from the invoked pop-up Window’s Object Space. Use the Contains method before changing a certain object in a certain Object Space. The use of a wrong Object Space causes an exception.

This method returns true for all non-persistent types.
