entity
Type: System..::..Object

[Missing <param name="entity"/> documentation for "M:NHibernate.Engine.ForeignKeys.GetEntityIdentifierIfNotUnsaved(System.String,System.Object,NHibernate.Engine.ISessionImplementor)"]

session
Type: NHibernate.Engine..::..ISessionImplementor

Return Value

[Missing <returns> documentation for "M:NHibernate.Engine.ForeignKeys.GetEntityIdentifierIfNotUnsaved(System.String,System.Object,NHibernate.Engine.ISessionImplementor)"]

Remarks

Used by OneToOneType and ManyToOneType to determine what id value should be used for an object that may or may not be associated with the session. This does a "best guess" using any/all info available to use (not just the EntityEntry).
