Type Parameters

• TEntityType
  TEntityType is the base type of entity this delta tracks changes for.

Constructors

	Name	Description
	Delta<TEntityType>()	Initializes a new instance of Delta<TEntityType>.
	Delta<TEntityType>(Type)	Initializes a new instance of Delta<TEntityType>.
	Delta<TEntityType>(Type, IEnumerable<String>)	Initializes a new instance of Delta<TEntityType>.

Properties

	Name	Description
	EntityType	Gets the actual type of the entity for which the changes are tracked.(Overrides TypedDelta.EntityType.)
	ExpectedClrType	(Overrides TypedDelta.ExpectedClrType.)

Methods

	Name	Description
	Clear()	Clears the Delta and resets the underlying Entity.(Overrides Delta.Clear().)
	CopyChangedValues(TEntityType)	Copies the changed property values from the underlying entity (accessible via GetEntity to the original entity.
	CopyUnchangedValues(TEntityType)	Copies the unchanged property values from the underlying entity (accessible via GetEntity ) to the original entity.
	Equals(Object)	(Inherited from Object.)
	Finalize()	(Inherited from Object.)
	GetChangedPropertyNames()	Returns the Properties that have been modified through this Delta as an enumeration of property names.(Overrides Delta.GetChangedPropertyNames().)
	GetDynamicMemberNames()	(Overrides DynamicObject.GetDynamicMemberNames().)
	GetEntity()	Returns the EntityType instance that holds all the changes (and original values) being tracked by this Delta.
	GetHashCode()	(Inherited from Object.)
	GetMetaObject(Expression)	(Inherited from DynamicObject.)
	GetType()	(Inherited from Object.)
	GetUnchangedPropertyNames()	Returns the properties that have not been modified through this Delta as an enumeration of property names.(Overrides Delta.GetUnchangedPropertyNames().)
	MemberwiseClone()	(Inherited from Object.)
	Patch(TEntityType)	Overwrites the original entity with the changes tracked by this Delta.
	Put(TEntityType)	Overwrites the original entity with the values stored in this Delta.

	TryGetIndex(GetIndexBinder, Object[], Object)	(Inherited from DynamicObject.)
	TryGetMember(GetMemberBinder, Object)	Overrides the DynamicObject TryGetMember method, so that only the properties of Entity can be got.(Inherited from Delta.)
	TryGetPropertyType(String, Type)	Attempts to get the Type of the property called name from the underlying entity.(Overrides Delta.TryGetPropertyType(String, Type).)
	TryGetPropertyValue(String, Object)	Attempts to get the value of the property called name from the underlying entity.(Overrides Delta.TryGetPropertyValue(String, Object).)
