PHP 클래스 ezcWorkflowNodeAction, Workflow

When the node is reached during execution of the workflow, the business logic that is implemented by the associated service object is executed. Service objects can return true to resume execution of the workflow or false to suspend the workflow (unless there are other active nodes) and be re-executed later Incoming nodes: 1 Outgoing nodes: 1 The following example displays how to create a workflow with a very simple service object that prints the argument it was given to the constructor:


whatToSay = $whatToSay;
    }

    public function execute( ezcWorkflowExecution $execution )
    {
        print $this->whatToSay;
        return true; // we're finished, activate next node
    }

    public function __toString()
    {
        return 'action description';
    }
}

$workflow = new ezcWorkflow( 'Test' );

$action = new ezcWorkflowNodeAction( array( "class" => "MyPrintAction",
                                            "arguments" => "No. 1 The larch!" ) );
$action->addOutNode( $workflow->endNode );
$workflow->startNode->addOutNode( $action );
?>

__construct() 공개 메소드

Configuration format

String: The class name of the service object. Must implement ezcWorkflowServiceObject. No arguments are passed to the constructor.
Array:
- class: The class name of the service object. Must implement ezcWorkflowServiceObject.
- arguments: Array of values that are passed to the constructor of the service object.

public __construct ( mixed $configuration )
$configuration	mixed

__toString() 공개 메소드

Returns a textual representation of this node.

public __toString ( ) : string
리턴	string

configurationFromXML() 공개 정적인 메소드

Generate node configuration from XML representation.

public static configurationFromXML ( DOMElement $element ) : array
$element	DOMElement
리턴	array

configurationToXML() 공개 메소드

Generate XML representation of this node's configuration.

public configurationToXML ( DOMElement $element )
$element	DOMElement

createObject() 보호된 메소드

Returns the service object as specified by the configuration.

protected createObject ( ) : ezcWorkflowServiceObject
리턴	ezcWorkflowServiceObject

execute() 공개 메소드

If the service object returns true, the output node will be activated. If the service node returns false the workflow will be suspended unless there are other activated nodes. An action node suspended this way will be executed again the next time the workflow is resumed.

public execute ( ezcWorkflowExecution $execution ) : boolean
$execution	ezcWorkflowExecution
리턴	boolean	true when the node finished execution, and false otherwise
