A log view adaptor is the storage interface for LogConsistentGrain<TView>, whose state is defined as a log view.

There is one adaptor per grain, which is installed by ILogViewAdaptorFactory when the grain is activated.

public interface ILogViewAdaptor<TLogView,TLogEntry> : Orleans.EventSourcing.ILogConsistencyDiagnostics, Orleans.EventSourcing.ILogViewRead<TLogView,TLogEntry>, Orleans.EventSourcing.ILogViewUpdate<TLogEntry> where TLogView : new()

type ILogViewAdaptor<'LogView, 'LogEntry (requires 'LogView : (new : unit -> 'LogView))> = interface
    interface ILogViewRead<'LogView, 'LogEntry (requires 'LogView : (new : unit -> 'LogView))>
    interface ILogViewUpdate<'LogEntry>
    interface ILogConsistencyDiagnostics

Public Interface ILogViewAdaptor(Of TLogView, TLogEntry)
Implements ILogConsistencyDiagnostics, ILogViewRead(Of TLogView, TLogEntry), ILogViewUpdate(Of TLogEntry)

Type Parameters

TLogView

Type for the log view

TLogEntry

Type for the log entry

Derived: Orleans.EventSourcing.Common.PrimaryBasedLogViewAdaptor<TLogView,TLogEntry,TSubmissionEntry>

Implements: ILogConsistencyDiagnostics ILogViewRead<TLogView,TLogEntry> ILogViewUpdate<TLogEntry>

Properties

ConfirmedVersion	The length of the confirmed prefix of the log (Inherited from ILogViewRead<TView,TLogEntry>)
ConfirmedView	Confirmed view of the log (reflecting only confirmed entries) (Inherited from ILogViewRead<TView,TLogEntry>)
TentativeView	Local, tentative view of the log (reflecting both confirmed and unconfirmed entries) (Inherited from ILogViewRead<TView,TLogEntry>)
UnconfirmedSuffix	A list of the submitted entries that do not yet appear in the confirmed prefix. (Inherited from ILogViewRead<TView,TLogEntry>)

Methods

ConfirmSubmittedEntries()	Confirm all submitted entries. Waits until all previously submitted entries appear in the confirmed prefix of the log. (Inherited from ILogViewUpdate<TLogEntry>)
DisableStatsCollection()	Turns off the statistics collection for this log-consistent grain. (Inherited from ILogConsistencyDiagnostics)
EnableStatsCollection()	Turns on the statistics collection for this log-consistent grain. (Inherited from ILogConsistencyDiagnostics)
GetStats()	Gets the collected statistics for this log-consistent grain. (Inherited from ILogConsistencyDiagnostics)
PostOnActivate()	Called during activation, right after the user-defined OnActivateAsync(CancellationToken)..
PostOnDeactivate()	Called during deactivation, right after the user-defined OnDeactivateAsync(DeactivationReason, CancellationToken).
PreOnActivate()	Called during activation, right before the user-defined OnActivateAsync(CancellationToken).
RetrieveLogSegment(Int32, Int32)	Attempt to retrieve a segment of the log, possibly from storage. Throws NotSupportedException if the log cannot be read, which depends on the providers used and how they are configured. (Inherited from ILogViewRead<TView,TLogEntry>)
Submit(TLogEntry)	Submit a single log entry to be appended to the global log, either at the current or at any later position. (Inherited from ILogViewUpdate<TLogEntry>)
SubmitRange(IEnumerable<TLogEntry>)	Submit a range of log entries to be appended atomically to the global log, either at the current or at any later position. (Inherited from ILogViewUpdate<TLogEntry>)
Synchronize()	Get the latest log view and confirm all submitted entries. Waits until all previously submitted entries appear in the confirmed prefix of the log, and forces a refresh of the confirmed prefix. (Inherited from ILogViewUpdate<TLogEntry>)
TryAppend(TLogEntry)	Try to append a single log entry at the current position of the log. (Inherited from ILogViewUpdate<TLogEntry>)
TryAppendRange(IEnumerable<TLogEntry>)	Try to append a range of log entries atomically at the current position of the log. (Inherited from ILogViewUpdate<TLogEntry>)
