PHP Class ezcWorkflowNodeParallelSplit, Workflow

The Parallel Split workflow pattern divides one thread of execution unconditionally into multiple parallel threads of execution. Use Case Example: After the credit card specified by the customer has been successfully charged, the activities of sending a confirmation email and starting the shipping process can be executed in parallel. Incoming nodes: 1 Outgoing nodes: 2..* This example creates a workflow that splits in two parallel threads which are joined again using a ezcWorkflowNodeDiscriminator.


startNode->addOutNode( $split );
$nodeExec1 = ....; // create nodes for the first thread of execution here..
$nodeExec2 = ....; // create nodes for the second thread of execution here..

$disc = new ezcWorkflowNodeDiscriminator();
$disc->addInNode( $nodeExec1 );
$disc->addInNode( $nodeExec2 );
$disc->addOutNode( $workflow->endNode );
?>
