UnitOfWork(CorrelationId, Action<IUnitOfWork>, IEventStore)

Represents an implementation of IUnitOfWork.

public UnitOfWork(CorrelationId correlationId, Action<IUnitOfWork> onCompleted, IEventStore eventStore)

Parameters

correlationId CorrelationId

The CorrelationId for the IUnitOfWork.

onCompleted Action<IUnitOfWork>

The action to call when the IUnitOfWork is completed.

eventStore IEventStore

The IEventStore to use for the IUnitOfWork.

Properties

CorrelationId

Gets the CorrelationId for the IUnitOfWork.

public CorrelationId CorrelationId { get; }

Property Value

CorrelationId

IsCompleted

Gets the value indicating whether the unit of work is completed.

public bool IsCompleted { get; }

Property Value

bool

Remarks

Unit of work being completed is semantically equal to it being disposed.

IsSuccess

Gets a value indicating whether the IUnitOfWork was successful.

public bool IsSuccess { get; }

Property Value

bool
