UPGRADE.md

Upgrade to 2.0 (formal 1.2)

checkTransition now use external Context

External Context can now optionaly provided. This feature was first planded to be version 1.2.0 / 1.2.1, but because of BC breaks (if Statemachine class was overwritten) it needs to be moved to 2.0. Except this change 2.0 is full compatible to 1.1. version.

Upgrade to 1.1

optional visualizing of the process graph by using clue/graph

To reduce dependencies, the visualizing of the process graph by using clue/graph is now optional. If you want to display process-graphs with GraphViz you have to add the clue/graph library to your composer.json

{
    "require": {
        "clue/graph": "~0.7"
    }
}

Changed graph generation class from inheritance to composite

To make graph part unit testable, the class was changed from inheritance from the graph class to use it as a composite.

The classname was also changed from Graph to GraphBuilder to make the change more visible.

Please change something like

$graph = new \Metabor\Statemachine\Graph\Graph();
$graph->addStateCollection($process);
// ...
$graphViz = new \Fhaculty\Graph\GraphViz($graph);

to

$graphBuilder = new \Metabor\Statemachine\Graph\GraphBuilder(new \Fhaculty\Graph\Graph());
$graphBuilder->addStateCollection($process);
// ...
$graphViz = new \Fhaculty\Graph\GraphViz($graphBuilder->getGraph());

removed example code from library

To slides and the example code from the conference talk have moved to the new repository metabor/statemachine-example.
