FiniteStateMachine

A finite state machine that will work with any provided by you states as long as you will describe a JSON file with states presented in a right format.

Getting Started

This app uses the Gradle build system.

• To build a project, enter the project directory and use the ./gradlew build command or use "Import Project" in Android Studio.
• Use ./gradlew test to run the unit test on your local host.

File Example

The JSON file must have an array of states. Each state is presented as:

  {
    "name": "AlarmDisarmed_AllUnlocked",
    "transition":
    [
      {"action": "LOCK", "next_state": "AlarmDisarmed_AllLocked"},
      {"action": "LOCKx2", "next_state": "AlarmArmed_AllLocked"},
      {"action": "UNLOCK", "next_state": "AlarmDisarmed_AllUnlocked"},
      {"action": "UNLOCKx2", "next_state": "AlarmDisarmed_AllUnlocked"}
    ]
  },

It has a name, and array of transitions. Transitions contain an action and a next state.

Also there has to be an initial state. The state from which the machine starts. It is described like this:

    {
    "initial_state" : "AlarmDisarmed_AllUnlocked"
    },

It has only a name. So, if you want to use the FiniteStateMachine class for your automaton, you should replace default values with yours.
