| /** |
| * This node implements the Synchronizing Merge workflow pattern. |
| * |
| * The Synchronizing Merge workflow pattern is to be used to synchronize multiple parallel |
| * threads of execution that are activated by a preceding Multi-Choice. |
| * |
| * Incoming nodes: 2..* |
| * Outgoing nodes: 1 |
| * |
| * This example displays how you can use ezcWorkflowNodeMultiChoice to activate one or more |
| * branches depending on the input and how you can use a synchronizing merge to merge them |
| * together again. Execution will not contiue until all activated branches have been completed. |
| * |
| * <code> |
| * <?php |
| * $workflow = new ezcWorkflow( 'Test' ); |
| * |
| * // wait for input into the workflow variable value. |
| * $input = new ezcWorkflowNodeInput( array( 'value' => new ezcWorkflowConditionIsInt ) ); |
| * $workflow->startNode->addOutNode( $input ); |
| * |
| * // create the exclusive choice branching node |
| * $choice = new ezcWorkflowNodeMultiChoice; |
| * $input->addOutNode( $choice ); |
| * |
| * $branch1 = ....; // create nodes for the first branch of execution here.. |
| * $branch2 = ....; // create nodes for the second branch of execution here.. |
| * |
| * // add the outnodes and set the conditions on the exclusive choice |
| * $choice->addConditionalOutNode( new ezcWorkflowConditionVariable( 'value', |
| * new ezcWorkflowConditionGreaterThan( 1 ) ), |
| * $branch1 ); |
| * $choice->addConditionalOutNode( new ezcWorkflowConditionVariable( 'value', |
| * new ezcWorkflowConditionGreaterThan( 10 ) ), |
| * $branch2 ); |
| * |
| * // Merge the two branches together and continue execution. |
| * $merge = new ezcWorkflowNodeSynchronizingMerge(); |
| * $merge->addInNode( $branch1 ); |
| * $merge->addInNode( $branch2 ); |
| * $merge->addOutNode( $workflow->endNode ); |
| * ?> |
