Remarks

Use the QAManagerBase::start() method to allow a QAManagerBase instance to listen for messages. There must be only a single instance of QAManagerBase per thread in your application.

You can use instances of this class to create and manage QAnywhere messages. Use the QAManagerBase::createBinaryMessage() method and the QAManagerBase::createTextMessage() method to create appropriate QAMessage instances. QAMessage instances provide a variety of methods to set message content and properties. To send QAnywhere messages, use the QAManager::putMessage() to place the addressed message in the local message store queue. The message is transmitted by the QAnywhere Agent based on its transmission policies or when you call the QAManagerBase::triggerSendReceive().

For more information about qaagent transmission policies, see Determining when message transmission should occur on the client.

Messages are released from memory when you close a QAManagerBase instance using the QAManagerBase::close().

You can use QAManagerBase::getLastError, QAManagerBase::getLastNativeError, and QAManagerBase::getLastErrorMessage to return error information when a QAException occurs. QAManagerBase also provides methods to set and get message store properties.

For more information, see Client message store properties and the MessageStoreProperties.
