PHP Класс ezcWorkflowNodeSimpleMerge, Workflow

The Simple Merge workflow pattern is to be used to merge the possible paths that are defined by a preceding Exclusive Choice. It is assumed that of these possible paths exactly one is taken and no synchronization takes place. Use Case Example: After the payment has been performed by either credit card or bank transfer, the order can be processed further. Incoming nodes: 2..* Outgoing nodes: 1 This example displays how you can use a simple merge to tie together two different execution paths from an exclusive choice into one.


 new ezcWorkflowConditionIsInt ) );
$workflow->startNode->addOutNode( $input );
create the exclusive choice branching node
$choice = new ezcWorkflowNodeExclusiveChoice;
$intput->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 ezcWorkflowConditionGreatherThan( 10 ) ),
                               $branch1 );
$choice->addConditionalOutNode( new ezcWorkflowConditionVariable( 'value',
                                                                 new ezcWorkflowConditionLessThan( 11 ) ),
                               $branch2 );
Merge the two branches together and continue execution.
$merge = new ezcWorkflowNodeSimpleMerge();
$merge->addInNode( $branch1 );
$merge->addInNode( $branch2 );
$merge->addOutNode( $workflow->endNode );
