EqualityComparer

An IEqualityComparer<T> for comparing key objects.

Methods

CreateEquatableKey(IUpdateEntry, Boolean)	Creates an equatable key object from the key values in the given entry. (Inherited from IPrincipalKeyValueFactory)
CreateFromBuffer(ValueBuffer)	Creates a key object from key values obtained from their indexed position in the given ValueBuffer.
CreateFromCurrentValues(IUpdateEntry)	Creates a key object from the key values in the given entry.
CreateFromKeyValues(IReadOnlyList<Object>)	Creates a key object from key values obtained in-order from the given enumerable.
CreateFromKeyValues(Object[])	Creates a key object from key values obtained in-order from the given array.
CreateFromOriginalValues(IUpdateEntry)	Creates a key object from the original key values in the given entry.
CreateFromRelationshipSnapshot(IUpdateEntry)	Creates a key object from the relationship snapshot key values in the given entry.
FindNullPropertyInCurrentValues(IUpdateEntry)	Finds the first null key value in the given entry and returns the associated IProperty.
FindNullPropertyInKeyValues(IReadOnlyList<Object>)	Finds the first null in the given in-order array of key values and returns the associated IProperty.
FindNullPropertyInKeyValues(Object[])	Finds the first null in the given in-order array of key values and returns the associated IProperty.
