#Description

A Pushdown Automaton toolkit for Kotlin. It's based on the State Manager from the Amethyst project.

A Pushdown Automaton is a combination of a Stack and a State Machine. Transitioning between states is accomplished via stack operations like push and pop, which allows you to encapsulate a state's behavior in a small single-responsibility class instead of making a class vary its behavior based on a variable.

#Usage

To set up a Pushdown Automaton, you'll need to:

  1. Declare a property for the state stack
  2. Declare state classes that provide the functionality for the automaton in that state.

#Prerequisites

  • ???

#Installation

If you use Gradle, in your dependencies:

implementation 'com.ravn.pushdown:pushdown:0.0.1'

#Development

I don't know yet; this is my first Kotlin library. ;)

#Author(s)

While Pushdown does not contain any Amethyst Game Engine source code, it does borrow heavily from its ideas and nomenclature. Many thanks to the Amethyst team for the inspiration.

Thanks also to Alyssa Verkade for the initial idea.
