Type Parameters

Name	Description

Shows whether the server has indicated that MergeAsync(TEntity, CancellationToken) is currently allowed.

Declaration

Nullable<bool> MergeAllowed { get; }

Property Value

Type	Description
Nullable<Boolean>	true if the method is allowed, false if the method is not allowed, null If no request has been sent yet or the server did not specify allowed methods.

Remarks

Uses cached data from last response.

Response

A cached copy of the entity as received from the server.

Declaration

TEntity Response { get; }

Property Value

Type	Description
TEntity

SetAllowed

Shows whether the server has indicated that SetAsync(TEntity, CancellationToken) is currently allowed.

Declaration

Nullable<bool> SetAllowed { get; }

Property Value

Methods

MergeAsync(TEntity, CancellationToken)

Modifies an existing TEntity by merging changes on the server-side.

Declaration

Task<TEntity> MergeAsync(TEntity entity, CancellationToken cancellationToken = null)

Parameters

Type	Name	Description
TEntity	entity	The TEntity data to merge with the existing one.
CancellationToken	cancellationToken	Used to cancel the request.

Returns

Type	Description
Task<TEntity>	The modified TEntity as returned by the server, possibly with additional fields set. null if the server does not respond with a result entity.

Exceptions

Type	Condition
InvalidOperationException	The entity has changed since it was last retrieved with ReadAsync(CancellationToken). Your changes were rejected to prevent a lost update.
InvalidDataException	BadRequest
AuthenticationException	Unauthorized
UnauthorizedAccessException	Forbidden
KeyNotFoundException	NotFound or Gone
HttpRequestException	Other non-success status code.

ReadAsync(CancellationToken)

Returns the TEntity.

Declaration

Task<TEntity> ReadAsync(CancellationToken cancellationToken = null)

Parameters

Type	Name	Description
CancellationToken	cancellationToken	Used to cancel the request.

Returns

Type	Description
Task<TEntity>

Exceptions

Type	Condition
AuthenticationException	Unauthorized
UnauthorizedAccessException	Forbidden
KeyNotFoundException	NotFound or Gone
HttpRequestException	Other non-success status code.

SetAsync(TEntity, CancellationToken)

Sets/replaces the TEntity.

Declaration

Task<TEntity> SetAsync(TEntity entity, CancellationToken cancellationToken = null)

Parameters

Type	Name	Description
TEntity	entity	The new TEntity.
CancellationToken	cancellationToken	Used to cancel the request.

Returns

Type	Description
Task<TEntity>	The TEntity as returned by the server, possibly with additional fields set. null if the server does not respond with a result entity.

Exceptions

Type	Condition
InvalidOperationException	The entity has changed since it was last retrieved with ReadAsync(CancellationToken). Your changes were rejected to prevent a lost update.
InvalidDataException	BadRequest
AuthenticationException	Unauthorized
UnauthorizedAccessException	Forbidden
KeyNotFoundException	NotFound or Gone
HttpRequestException	Other non-success status code.

UpdateAsync(Action<TEntity>, Int32, CancellationToken)

Reads the current state of the entity, applies a change to it and stores the result. Applies optimistic concurrency using automatic retries.

Declaration

Task<TEntity> UpdateAsync(Action<TEntity> updateAction, int maxRetries = 3, CancellationToken cancellationToken = null)

Parameters

Type	Name	Description
Action<TEntity>	updateAction	A callback that takes the current state of the entity and applies the desired modifications.
Int32	maxRetries	The maximum number of retries to perform for optimistic concurrency before giving up.
CancellationToken	cancellationToken	Used to cancel the request.

Returns

Type	Description
Task<TEntity>	The TEntity as returned by the server, possibly with additional fields set. null if the server does not respond with a result entity.

Exceptions

Type	Condition
InvalidOperationException	The number of retries performed for optimistic concurrency exceeded maxRetries.
InvalidDataException	BadRequest
AuthenticationException	Unauthorized
UnauthorizedAccessException	Forbidden
KeyNotFoundException	NotFound or Gone
HttpRequestException	Other non-success status code.

UpdateAsync(Action<JsonPatchDocument<TEntity>>, Int32, CancellationToken)

Applies a JSON Patch to the entity. Sends the patch instructions to the server for processing; falls back to local processing with optimistic concurrency if that fails.

Declaration

Task<TEntity> UpdateAsync(Action<JsonPatchDocument<TEntity>> patchAction, int maxRetries = 3, CancellationToken cancellationToken = null)

Parameters

Type	Name	Description
Action<JsonPatchDocument<TEntity>>	patchAction	Callback for building a patch document describing the desired modifications.
Int32	maxRetries	The maximum number of retries to perform for optimistic concurrency before giving up.
CancellationToken	cancellationToken	Used to cancel the request.

Returns

Type	Description
Task<TEntity>	The TEntity as returned by the server, possibly with additional fields set. null if the server does not respond with a result entity.

Exceptions

Type	Condition
InvalidOperationException	The number of retries performed for optimistic concurrency exceeded maxRetries.
NotSupportedException	Serializer is not a JsonMediaTypeFormatter.
InvalidDataException	BadRequest
AuthenticationException	Unauthorized
UnauthorizedAccessException	Forbidden
