This instance method dequeues messages from a queue using the supplied dequeue options.
Declaration
// C#
public OracleAQMessage Dequeue(OracleAQDequeueOptions dequeueOptions);
Parameters
dequeueOptions
An OracleAQDequeueOptions object.
Return Value
An OracleAQMessage instance representing the dequeued message.
Exceptions
InvalidOperationException - The connection is not open.
ObjectDisposedException - The object is already disposed.
OracleException - In case of timeout, an exception is thrown with the message, ORA-25228: timeout or end-of-fetch during message dequeue from queue_name. Timeout may happen if DequeueOptions.Wait is set to a value other than -1.
Remarks
If the supplied dequeueOptions object is null, then the dequeue options default values are used. The queue object's DequeueOptions property is ignored for this operation.
Calling this method does not change the DequeueOptions property of the queue.
The MessageType property must be set appropriately before calling this function. If the MessageType is OracleAQMessageType.UDT, then the UdtTypeName property must also be set.
Dequeued buffered messages always have null MessageId values.
