View source for Routed-dequeue

==Description==

Used to make a routing mechanism at the level of communication channel, based on some conditions applied to the buffer GVBuffer.

=={{VULCON}} / {{GVCONSOLE}} Configuration==

During the execution of flows, the operation is seen as a simple dequeue. 

The implementation of the routed-dequeue check the conditions and invokes a sub-operations accordingly.

To configure a routed-dequeue is necessary:
* defines sub-operations: Each sub operation is identified by a unique name within the routed-dequeue. The sub-operation can be selected are only those of type "dequeue". 
* defines routing conditions: Check the values in GVBuffer fields. Each routing condition has a unique name within the routed-dequeue.
* associate routing conditions to operations: Sub items 'VCLRouting' associate routing conditions with operations. The evaluation order is defined by the order of items 'VCLRouting'. The sub-operation is performed corresponding to the first condition verified.

The routed-dequeue Element is used by [[Channel]] and [[routed-dequeue]]. Its attributes are:
{|class="gvtable"
! Attribute !! Type !! Description

|-
| class || fixed || This attribute must assume the value '''it.greenvulcano.gvesb.virtual.RoutedDequeue'''.
|-
| name || optional || Operation name. Used in the 'Flow' section to associate workflow nodes to VCL operations.
