Interfaces for a Synchronous Batch-Supported Send Adapter

Batch-aware adapters may send messages synchronously or asynchronously, and may perform transacted send operations. To send batches of messages, a send adapter must implement the following interfaces:

• IBTTransport

• IBaseComponent

• IBTTransportControl

• IPersistPropertyBag

• IBTBatchTransmitter

• IBTTransmitterBatch

  For the synchronous batch send, the Messaging Engine gets a batch from the adapter and adds messages to be transmitted to that batch. The Messaging Engine adds each message to the batch and sends the messages only when it calls the Done method on the batch. The adapter returns True for bDeleteMessage for each message that it intends to transmit synchronously. The adapter should save message data, as opposed to a message pointer, in its TransmitMessage implementation. This is because the message pointer is no longer valid after True is returned, and should not be used or cached for later use.

  The following figure shows the object interactions involved in creating a synchronous batch-supported send adapter.
