ITransactedSessionCreateFlow(FlowProperties, IEndpoint, ISubscription, EventHandlerMessageEventArgs, EventHandlerFlowEventArgs, EndpointProperties) Method

Creates a consumer flow IFlow on the given transacted session. If messageEventHandler delegate is provided, messages received on the flow are dispatched to the message callback delegate in the context of the message dispatcher thread (CreateMessageDispatcher), otherwise messages received on this consumer flow are queued internally; in this case client applications must call ReceiveMsg(Int32) directly to retrieve any internally queued messages. Unlike other (or non-transacted) flows, events and messages received on a transacted flow are delivered in the contexts of two different threads. Events received on flows are still delivered in the context of the IContext thread (IContext). Messages received on flows are dispatched to the messageEventHandler delegate in the context of the message dispatcher thread or retrieved by calling ReceiveMsg(Int32) directly in the context of an application thread. The following flow properties are not supported: AckModeAutoAck
