ProcessMaker Nayra is a package that provides base classes to implement a process execution engine. This includes patterns to implement activities, events and gateways.

How to execute a process

Load a BPMN definition

 $bpmnRepository = new BpmnDocument(); $bpmnRepository->setEngine($this->engine); $bpmnRepository->setFactory($this->repository); $bpmnRepository->load('files/ParallelGateway.bpmn'); 

Get a reference to the process

 $process = $bpmnRepository->getProcess('ParallelGateway'); 

Create a data storage

 $dataStore = $this->repository->createDataStore(); 

Create a process instance

 $instance = $this->engine->createExecutionInstance($process, $dataStore); 

Trigger the start event

 $start = $bpmnRepository->getStartEvent('StartEvent'); $start->start($instance); 

Execute tokens and run to the next state

 $this->engine->runToNextState(); 

One token arrives to the first task

 $firstTask = $bpmnRepository->getScriptTask('start'); $token = $firstTask->getTokens($instance)->item(0); 

Complete the first task

 $startActivity->complete($token); 

Execute tokens and run to the next state

 $this->engine->runToNextState(); 

One token arrives to the second task and one to the third task

 $secondTask = $bpmnRepository->getScriptTask('ScriptTask_1'); $token1 = $secondTask->getTokens($instance)->item(0); $thirdTask = $bpmnRepository->getScriptTask('ScriptTask_2'); $token2 = $thirdTask->getTokens($instance)->item(0);
