Type Parameters

TEntry

The interface type of the log entries supported by audit trail.

ReadAsync<TEntryImpl, TList>(TList, long?, CancellationToken)

Reads log entries asynchronously.

Declaration
ValueTask<TResult> ReadAsync<TEntryImpl, TList>(TList entries, long? snapshotIndex, CancellationToken token) where TEntryImpl : TEntry where TList : IReadOnlyList<TEntryImpl>
Parameters
Type Name Description
TList entries

The list of the log entries.
long? snapshotIndex

Non-null if the first log entry in this list is a snapshot entry that has the specific index.
CancellationToken token

The token that can be used to cancel the operation.
Returns
Type Description
ValueTask<TResult>

The result returned by the reader.
Type Parameters
Name Description
TEntryImpl

The actual type of the log entries in the list.
TList

The type of the list containing log entries.
Remarks

The actual generic types for TEntryImpl and TList are supplied by the infrastructure automatically. Do not return TEntryImpl as a part of TResult because log entries are valid only during the call of this method.
