Methods

GetIdentity(Object)

Extracts the identity from the object if it has one.

Declaration
public static Identity GetIdentity(this object value)
Parameters
Type Name Description
System.Object value

The object to check for identity

Returns
Type Description
Identity

A Identity instance or null if the object does implement its own identity

Remarks

The algorith used to extract identity is as follows:

  1. The object is checked to see if it implements the IDynamicData interface and if so its Id property is called.
  2. The object is reflected to search for a property named Id with a getter whose type is either Identity or System.Guid
  3. The object is checked to see if it implements the IEntity interface and if so its ID and UniqueId properties are called

SetIdentity(Object, Identity)

Sets the identity into the object if supported

Declaration
public static void SetIdentity(this object value, Identity id)
Parameters
Type Name Description
System.Object value

The object to set the identity in

Identity id

The Identity to set

Remarks

The algorith used to set identity is as follows:

  1. The object is checked to see if it implements the IDynamicData interface and if so its Id property is set.
  2. The object is reflected to search for a property named Id with a setter whose type is either Identity or System.Guid
  3. The object is checked to see if it implements the IEntity interface and if so its Id property is set.
