DatabaseClassAttribute

Namespace: VeloxDB.ObjectInterface

Assembly: vlxdb.dll

Syntax

public sealed class DatabaseClassAttribute : Attribute

Remarks

Apply the DatabaseClassAttribute to classes that are part of the model. A database class must fulfill the following requirements:

• It must be declared as abstract
• It must inherit from DatabaseObject
• It must have an empty constructor
• Properties that need to be persisted must be marked with DatabasePropertyAttribute
• Persisted properties must be abstract with both getter and setter defined

Examples

[DatabaseClass]
public abstract partial class Post : DatabaseObject
{
    [DatabaseProperty]
    public abstract string Title { get; set; }

    [DatabaseProperty]
    public abstract string Content { get; set; }

    [DatabaseReference(false, DeleteTargetAction.CascadeDelete, true)]
    public abstract Blog Blog { get; set; }

    public partial PostDTO ToDTO();
    public static partial Post FromDTO(ObjectModel om, PostDTO post);
}
