Struct UInt64LinksTransactionsLayer.Transition

Namespace

Platform.Data.Doublets

Assembly

Platform.Data.Doublets.dll

Records a transaction transition between two link states.

public struct UInt64LinksTransactionsLayer.Transition : IEquatable<UInt64LinksTransactionsLayer.Transition>

Implements

IEquatable<UInt64LinksTransactionsLayer.Transition>

Inherited Members

object.Equals(object, object)

object.GetType()

object.ReferenceEquals(object, object)

Remarks

Альтернативные варианты хранения трансформации (элемента транзакции):

private enum TransitionType { Creation, UpdateOf, UpdateTo, Deletion }

private struct Transition { public TLinkAddress TransactionId; public UniqueTimestamp Timestamp; public TransactionItemType Type; public Link Source; public Link Linker; public Link Target; }

Или

public struct TransitionHeader { public TLinkAddress TransactionIdCombined; public TLinkAddress TimestampCombined;

public TLinkAddress TransactionId
{
    get
    {
        return (TLinkAddress) mask & TransactionIdCombined;
    }
}

public UniqueTimestamp Timestamp
{
    get
    {
        return (UniqueTimestamp)mask & TransactionIdCombined;
    }
}

public TransactionItemType Type
{
    get
    {
        // Использовать по одному биту из TransactionId и Timestamp,
        // для значения в 2 бита, которое представляет тип операции
        throw new NotImplementedException();
    }
}

}

private struct Transition { public TransitionHeader Header; public Link Source; public Link Linker; public Link Target; }
