ProcessMaker Nayra
==================

[](#processmaker-nayra)

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
------------------------

[](#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');

```

[![ParallelGateway diagram](/docs/diagrams/ParallelGateway.svg "ParallelGateway diagram")](/docs/diagrams/ParallelGateway.svg)

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);

```

[![Start Event](/docs/diagrams/ParallelGateway_1.svg "Start Event")](/docs/diagrams/ParallelGateway_1.svg)

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);

```

[![First task](/docs/diagrams/ParallelGateway_2.svg "First task")](/docs/diagrams/ParallelGateway_2.svg)

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);

```
