| ## How to create a diagram for an FSM? | ||
| Squirrel framework has support of transforming an FSM to a DOT file, which a textual representation of an FSM metadata. | ||
| To create a DOT file you can execute in java: | ||
| ``` | ||
| DotVisitor visitor = SquirrelProvider.getInstance().newInstance(DotVisitor.class); | ||
| anInstanceOfYourFsm.accept(visitor); | ||
| visitor.convertDotFile("src/main/resources/YourFsm"); | ||
| ``` | ||
| A DOT file, produced by this code, could be converted into a picture by using | ||
| one of the converters available on the Internet. | ||
|
|
||
| Since we need to instantiate an FSM class to build a DOT file, we need to put this code into some module that has | ||
| all necessary dependencies. One of the ways is to use a unit test in the same package where an FSM is located. | ||
| For building a diagram we might not need to instantiate all the classes responsible for actions. For a diagram containing | ||
| only states, events, and transitions, it is enough to copy-paste the FSM builder part without any `perform` methods. | ||
| An example of this approach is `HaFlowUpdateFsmDiagramTest`. |

| # FSM Overview | ||
| FSM stands for [finite-state machine](https://en.wikipedia.org/wiki/Finite-state_machine), | ||
| it is a model for computation of some process that changes its state in response to some input. | ||
|
|
||
| In OpenKilda, FSM is a central component for computing processes such as Flow creation, Switch synchronization, and others. | ||
| Input for FSMs could be users input or a response from services, for example responses from switches about rules installation. | ||
|
|
||
| [Squirrel State Machine framework](https://hekailiang.github.io/squirrel/) has been chosen as the implementation of the FSM orchestrator. | ||
| It is agreed to name classes responsible for the processes computation using this framework with the suffix `Fsm`: | ||
| HaFlowUpdateFsm, SwitchSyncFsm. | ||
| In the context of OpenKilda, "FSM" often is a casual broad term that refer to infrastructure or a family of classes that are responsible | ||
| for handling some specific process. |
