ReflectionDictionary Class

Implements the XPDictionary class. Provides metadata information accumulated via .NET Reflection (based on class structure and custom attributes).

Namespace: DevExpress.Xpo.Metadata

Assembly: DevExpress.Xpo.v21.1.dll

Declaration

C#

public class ReflectionDictionary :
    XPDictionary

VB.NET

Public Class ReflectionDictionary
    Inherits XPDictionary

Remarks

Note

When collecting metadata information for persistent classes, all the necessary code for constructor calls and accessors to public fields and properties is created using MSIL instructions (via reflection emit). This ensures that the ReflectionDictionary maintains a high performance when creating and accessing persistent objects.
