scala-statecharts

A statecharts library written in Scala.

Implemented

• FSM - Finite-state machine.

  • One state is defined as the initial state. When a machine starts to execute, it automatically enters this state
  • Each state can define actions that occur when a machine enters or exits that state. Actions will typically have side effects
  • Each state can define events that trigger a transition
  • A transition defines how a machine would react to the event, by exiting one state and entering another state
  • A transition can define actions that occur when the transition happens. Actions will typically have side effects

• UML - Executable UML statechart.

  • Asynchronous statechart processing
  • Recovery capability (start from last successful transition)
  • No need to translate diagrams into code
  • No bugs introduced by hand translation of diagrams

Getting started

The library is available for the JVM Runtime using Scala 2.12, 2.13.
