    Get all revisions

    • Use GetFor to retrieve all of the revisions currently kept for the specified document.

    Example:

    // Get revisions for document 'orders/1-A'
// Revisions will be ordered by most recent revision first
List<Order> orderRevisions = session
    .Advanced
    .Revisions
    .GetFor<Order>(id: "orders/1-A", start: 0, pageSize: 10);
    // Get revisions for document 'orders/1-A'
// Revisions will be ordered by most recent revision first
List<Order> orderRevisions = await asyncSession
    .Advanced
    .Revisions
    .GetForAsync<Order>(id: "orders/1-A", start: 0, pageSize: 10);

    Syntax:

    List<T> GetFor<T>(string id, int start = 0, int pageSize = 25);
    Parameters Type Description
    id string Document ID for which to retrieve revisions
    start int First revision to retrieve, used for paging
    pageSize int Number of revisions to retrieve per results page

    Get revisions metadata

    • Use GetMetadataFor to retrieve the metadata for all the revisions currently kept for the specified document.

    Example:

    // Get revisions' metadata for document 'orders/1-A'
List<MetadataAsDictionary> orderRevisionsMetadata = session
    .Advanced
    .Revisions
    .GetMetadataFor(id: "orders/1-A", start: 0, pageSize: 10);

// Each item returned is a revision's metadata, as can be verified in the @flags key
var metadata = orderRevisionsMetadata[0];
var flagsValue = metadata.GetString(Constants.Documents.Metadata.Flags);

Assert.Contains("Revision", flagsValue);
    // Get revisions' metadata for document 'orders/1-A'
List<MetadataAsDictionary> orderRevisionsMetadata = await asyncSession
    .Advanced
    .Revisions
    .GetMetadataForAsync(id: "orders/1-A", start: 0, pageSize: 10);

// Each item returned is a revision's metadata, as can be verified in the @flags key
var metadata = orderRevisionsMetadata[0];
var flagsValue = metadata.GetString(Constants.Documents.Metadata.Flags);

Assert.Contains("Revision", flagsValue);

    Syntax:

    List<MetadataAsDictionary> GetMetadataFor(string id, int start = 0, int pageSize = 25);
    Parameters Type Description
    id string Document ID for which to retrieve revisions' metadata
    start int First revision to retrieve metadata for, used for paging
    pageSize int Number of revisions to retrieve per results page

    Get revisions by creation time

    • Use Get to retrieve a revision by its creation time.

    Example:

    // Get a revision by its creation time
Order revisionFromLastYear = session
    .Advanced
    .Revisions
     // If no revision was created at the specified time,
     // then the first revision that precedes it will be returned
    .Get<Order>("orders/1-A", DateTime.Now.AddYears(-1));
    // Get a revision by its creation time
Order revisionFromLastYear = await asyncSession
    .Advanced
    .Revisions
    // If no revision was created at the specified time,
    // then the first revision that precedes it will be returned
    .GetAsync<Order>("orders/1-A", DateTime.Now.AddYears(-1));

    Syntax:

    T Get<T>(string id, DateTime date);
    Parameter Type Description
    id string Document ID for which to retrieve the revision by creation time
    date DateTime The revision's creation time

    Get revisions by change vector

    • Use Get to retrieve a revision or multiple revisions by their change vectors.

    Example:

    // Get revisions metadata 
List<MetadataAsDictionary> revisionsMetadata = session
    .Advanced
    .Revisions
    .GetMetadataFor("orders/1-A", start: 0, pageSize: 25);

// Get the change-vector from the metadata
var changeVector = revisionsMetadata[0].GetString(Constants.Documents.Metadata.ChangeVector);

// Get the revision by its change-vector
Order revision = session
    .Advanced
    .Revisions
    .Get<Order>(changeVector);
    // Get revisions metadata 
List<MetadataAsDictionary> revisionsMetadata = await asyncSession
    .Advanced
    .Revisions
    .GetMetadataForAsync("orders/1-A", start: 0, pageSize: 25);

// Get the change-vector from the metadata
var changeVector = revisionsMetadata[0].GetString(Constants.Documents.Metadata.ChangeVector);

// Get the revision by its change-vector
Order revision = await asyncSession
    .Advanced
    .Revisions
    .GetAsync<Order>(changeVector);

    Syntax:

    // Get a revision by its change vector
T Get<T>(string changeVector);

// Get multiple revisions by their change vectors
Dictionary<string, T> Get<T>(IEnumerable<string> changeVectors);
    Parameter Type Description
    changeVector string The revision's change vector
    changeVectors IEnumerable<string> Change vectors of multiple revisions
