VB.NET

Public Interface IXPSimpleObject
    Inherits IXPClassInfoAndSessionProvider,
             IXPClassInfoProvider,
             IXPDictionaryProvider,

             IDataLayerProvider

Remarks

To make any object persistent (so that it can be stored to/restored from a data store) you can implement the IXPSimpleObject interface for a custom object. You can also implement the IXPObject interface instead, if you need to have more control over the object’s lifetime.

The base class that implements the IXPObject interface is XPBaseObject. So, rather than implementing the IXPSimpleObject or IXPObject interface for a custom object, you can inherit it from the XPBaseObject class, or one of its descendants.

It’s also possible to make any object persistent, by using the PersistentAttribute attribute.

Note

When implementing the IXPSimpleObject interface, it is recommended that you implement a constructor that takes a Session parameter.
