getSubExecution() public method

If this method is used to resume a subworkflow you must provide the execution id through $id. If $interactive is false an ezcWorkflowExecutionNonInteractive will be returned. This method can be used by nodes implementing sub-workflows to get a new execution environment for the subworkflow.
public getSubExecution ( integer $id = null, boolean $interactive = true ) : ezcWorkflowExecution
$id integer
$interactive boolean
