Methods

CreateDependentEquatableKey(IUpdateEntry, Boolean)	Creates an equatable key object from the foreign key values in the given entry. (Inherited from IDependentKeyValueFactory)
CreatePrincipalEquatableKey(IUpdateEntry, Boolean)	Creates an equatable key object from the key values in the given entry. (Inherited from IDependentKeyValueFactory)
TryCreateFromBuffer(ValueBuffer, TKey)	Attempts to create a key instance using foreign key values from the given ValueBuffer.
TryCreateFromCurrentValues(IUpdateEntry, TKey)	Attempts to create a key instance using foreign key values from the given IUpdateEntry.
TryCreateFromOriginalValues(IUpdateEntry, TKey)	Attempts to create a key instance using original foreign key values from the given IUpdateEntry.
TryCreateFromPreStoreGeneratedCurrentValues(IUpdateEntry, TKey)	Attempts to create a key instance from the given IUpdateEntry using foreign key values that were set before any store-generated values were propagated.
TryCreateFromRelationshipSnapshot(IUpdateEntry, TKey)	Attempts to create a key instance from the given IUpdateEntry using foreign key values from the previously known relationship.
