This attribute indicates the type of operation that must execute.

• wait
• change GVBuffer
• end.

DequeueFilter

Used in GVOperationNode with op-type set to dequeue, allows you to define the criteria for receiving messages.
Will be received only messages that meet the criteria.

This element has not attributes.

May have one or more subelements of the following types:

• IDFilter: would set the criteria of the received message ID.
• RetCodeFilter: would set the criteria on the return code of the received message.
• SystemFilter: would set the criteria field system of the received message.
• ServiceFilter: would set the criteria in the field service of the received message.
• PropertyFilter: would set the criteria on the properties of the received message

If multiple policies are specified, then the message to receive must meet them all.
