SimplePNML for JVM

Simple JVM implementation of the Petri Net Markup Language (PNML), limited to Place-Transition-(PT)-Nets

Check out SimplePNML for .NET to handle PNML files from .NET languages like C# and VB.NET!

Motivation

The Petri Net Markup Language (PNML) was developed as an interchange format for petri nets. It can describe logical relations between petri net elements as well as visualization information. Its high expandability and conceptual support for a variety of different petri net types comes with the price of high complexity. Since most use cases and applications are focused on Place-Transition-(PT)-Nets, this library provides a simple way to access and modify this kind of petri nets programmatically.

Installation

Usage

// Create a place, a transition and an arc
Place place = Place.builder()
	.id("my-place")
	.initialMarking(new Label("1"))
	.build();
Transition transition = Transition.builder()
	.id("my-transition")
	.build();
Arc arc = Arc.builder()
	// no explicit identifier
	.inscription(new Label("1"))
	.build();

// Let the arc connect the place and the transition
arc.connect(place, transition);

// Add all the elements to a new page
Page page = new Page();
page.getPlaces().add(page);
page.getTransitions().add(transition);
page.getArcs().add(arc);

Differences to .NET version

The element relations can be accessed via getters and setters.
Naming conventions from the Java world are applied. This includes:
- Methods are named using camelCase.
- Enum members are named using UPPER_CASE.
The Builder pattern can be used to construct objects.
