# Simple Final State Machine
see an example here: https://github.com/bvn13/JIrcBot/blob/master/src/main/java/ru/bvn13/jircbot/listeners/calculator/CalculatorDialog.java
Each instance of State Machine must be prepared with:
1. Initial state
2. Finish state - may be not several states
3. Intermediate states - optionally
4. All transitions needed
Each State may be specified with handlers:
1. Before handler - is called right before FSM changes INTO this state
2. After handler - is called right before FSM changes FROM this state to another
3. Processor - the method to process events
Transition is the Rule providing FSM the possibility to change between states.
Each transition must be determined in terms of:
1. From State - mandatory
2. To State - mandatory
3. Condition - optionally. If specified, the FSM will check the condition in order to check the possibility
to change from FROM State into TO State
## Example
Simple way to use it - to construct an inherited class specified with the type of events to be processed
during transitions.
```java
SimpleFsm<String> simpleFsm = Fsm
.<SimpleFsm<String>, String>from(SimpleFsm::new)
.withStates()
.from("init")
.withBeforeHandler(fsm -> initBefore.set(true))
.withAfterHandler(fsm -> initAfter.set(true))
.withProcessor((fsm, event) -> initProcess.set(true))
.end()
.finish("finish")
.withBeforeHandler(fsm -> finishBefore.set(true))
.withAfterHandler(fsm -> finishAfter.set(true))
.withProcessor((fsm, event) -> finishProcess.set(true))
.end()
.withTransition()
.from("init")
.to("finish")
.checking((fsm, event) -> true)
.end()
.create();
```
## Releasing
Creating a new release involves the following steps:
1. `./mvnw gitflow:release-start gitflow:release-finish`
2. `git push origin master`
3. `git push --tags`
4. `git push origin develop`
In order to deploy the release to Maven Central, you need to create an account at https://issues.sonatype.org and
configure your account in `~/.m2/settings.xml`:
```xml
<settings>
<servers>
<server>
<id>ossrh</id>
<username>your-jira-id</username>
<password>your-jira-pwd</password>
</server>
</servers>
</settings>
```
The account also needs access to the project on Maven Central. This can be requested by another project member.
Then check out the release you want to deploy (`git checkout x.y.z`) and run `./mvnw deploy -Prelease`.
