PHP Class ezcWorkflowNodeInput, Workflow

When the node is reached, the workflow engine will suspend the workflow execution if the specified input data is not available (first activation). While the workflow is suspended, the application that embeds the workflow engine may supply the input data and resume the workflow execution (second activation of the input node). Input data is stored in a workflow variable. Incoming nodes: 1 Outgoing nodes: 1 This example creates a simple workflow that expectes two input variables, once which can be any value and another that can only be an integer between one and ten.


 new ezcWorkflowConditionIsAnything,
  'intVar'   => new ezcWorkflowConditionAnd(
    array(
      new ezcWorkflowConditionIsInteger,
      new ezcWorkflowConditionIsGreatherThan( 0 )
      new ezcWorkflowConditionIsLessThan( 11 )
    )
  )
);

$input->addOutNode( $workflow->endNode );
$workflow->startNode->addOutNode( $input );
?>
