A class the tracks changes (i.e. the Delta) for a particular TStructuralType.

public class Delta<TStructuralType> : Microsoft.AspNet.OData.TypedDelta where TStructuralType : class

type Delta<'StructuralType (requires 'StructuralType : null)> = class
    inherit TypedDelta
    interface IDelta

Public Class Delta(Of TStructuralType)
Inherits TypedDelta

Type Parameters

TStructuralType

TStructuralType is the type of the instance this delta tracks changes for.

Inheritance: DynamicObject

Delta

TypedDelta
Delta<TStructuralType>

Implements: IDelta

Constructors

Delta<TStructuralType>()	Initializes a new instance of Delta<TStructuralType>.
Delta<TStructuralType>(Type, IEnumerable<String>, PropertyInfo)	Initializes a new instance of Delta<TStructuralType>.
Delta<TStructuralType>(Type, IEnumerable<String>)	Initializes a new instance of Delta<TStructuralType>.
Delta<TStructuralType>(Type)	Initializes a new instance of Delta<TStructuralType>.

Properties

ExpectedClrType	Gets the expected type of the entity for which the changes are tracked.
StructuredType	Gets the actual type of the structural object for which the changes are tracked.

Methods

Clear()	Clears the IDelta.
CopyChangedValues(TStructuralType)	Copies the changed property values from the underlying entity (accessible via GetInstance()) to the `original` entity recursively.
CopyUnchangedValues(TStructuralType)	Copies the unchanged property values from the underlying entity (accessible via GetInstance()) to the `original` entity.
GetChangedPropertyNames()	Returns the known properties that have been modified through this Delta as an IEnumerable<T> of property Names. Includes the structural properties at current level. Does not include the names of the changed dynamic properties.
GetInstance()	Returns the instance that holds all the changes (and original values) being tracked by this Delta.
GetUnchangedPropertyNames()	Returns the known properties that have not been modified through this Delta as an IEnumerable<T> of property Names. Does not include the names of the changed dynamic properties.
Patch(TStructuralType)	Overwrites the `original` entity with the changes tracked by this Delta. The semantics of this operation are equivalent to a HTTP PATCH operation, hence the name.
Put(TStructuralType)	Overwrites the `original` entity with the values stored in this Delta. The semantics of this operation are equivalent to a HTTP PUT operation, hence the name.
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.
TryGetPropertyValue(String, Object)	Attempts to get the value of the Property called `name` from the underlying Entity.
TrySetMember(SetMemberBinder, Object)	Overrides the DynamicObject TrySetMember method, so that only the properties of Entity can be set. (Inherited from Delta)
TrySetPropertyValue(String, Object)	Attempts to set the Property called `name` to the `value` specified.
