![]() | ActualSchema | Gets or sets the current resolved IDataSourceSchema for the provider. |
![]() | BatchCompleted | Gets a callback to invoke when a batch request has completed. |
![]() | ExecutionContext | Gets the execution context to synchronize with when reporting on loaded pages. |
![]() | PageLoaded | Gets a callback to invoke when a page request has finished loading. |
![]() | PopulatedActualPageSize | Gets or sets whether ActualPageSize has been populated with a coerced value and should be retained, regardless as to whether non-full pages are seen. |
![]() | Tasks | Gets the currently active set of requests for the worker. |
Name | Description | |
---|---|---|
![]() | AddPageRequest | Adds a new page request to the worker. |
![]() | AddPageRequestWithRetry | Adds a page request with the specified retry delay. |
![]() | CreateBatchRequest | Create a batch request with the provided changes. |
![]() | RemoveAllPageRequests | Removes all pending or active page requests from the worker. |
![]() | RemovePageRequest | Removes a page request with the specifiec index from the worker. |
![]() | Shutdown | Causes the worker to shut down its operation. Worker should not be reused once entered into this state. |
Name | Description | |
---|---|---|
![]() | AwaitChanges | Called by the worker to perform a timed wait for changes to occur. |
![]() | CheckAndPotentiallyWaitOnTasks | Checks the status of the current tasks, and if possible, yields until changes occur to the active tasks or the worker settings. |
![]() | DoWork | The main loop for the worker. |
![]() | GetCompletedTaskData | Populates the implementation specific data for the specified completed task. |

![]() | MakeTaskForRequest | Orverride to specify how a task gets constructed for a request. |
![]() | ProcessCompletedTask | Override to specify how a completed task is handled. This should call the PageLoaded callback, synchronizing with the ExecutionContext, if a page has been successfully loaded. |
![]() | RemoveCompletedTaskData | Override to specify how implementation specific data gets removed for a completed task. |
![]() | RetryIndex | Retries a request with the requested delay. |
![]() | SignalChangesOcurred | Called to indicate that something changed that should immediately wake the worker to further process the active requests. |
