Interface for generation of unique IDs for new IEntity objects.

Object Model

Syntax

Visual Basic
C#

'Declaration
 
<InterfaceExportAttribute(ContractName="", ContractType=IdeaBlade.EntityModel.IIdGenerator)>
Public Interface IIdGenerator

'Usage
 
Dim instance As IIdGenerator

[InterfaceExport(ContractName="", ContractType=IdeaBlade.EntityModel.IIdGenerator)]
public interface IIdGenerator

Remarks

The IIdGenerator interface defines methods to generate both temporary and real IDs for IEntity objects, and to map the temporary IDs to real IDs when objects are persisted to a backend data source. Temporary IDs are created via a call to EntityManager.GenerateId, and allow entities to be created and uniquely identified while the EntityManager is disconnected from a backend database. Temporary IDs are mapped to real IDs during EntityManager.SaveChanges processing.

Sample code in both VB.NET and C# showing an implementation for numeric ID values is provided with the DevForce installation.
