Package com.tnsai.fsm

Class StateMachineVisualizer

java.lang.Object
com.tnsai.fsm.StateMachineVisualizer
public final class StateMachineVisualizer extends Object
Generates visual representations of state machines.

Supports export to Mermaid and Graphviz (DOT) formats for documentation and debugging purposes.

Usage


 StateMachine sm = ...; // your state machine

 // Export to Mermaid
 String mermaid = StateMachineVisualizer.toMermaid(sm);
 System.out.println(mermaid);
 // Output:
 // stateDiagram-v2
 //     [*] --> IDLE
 //     IDLE --> PROCESSING : START
 //     PROCESSING --> COMPLETED : FINISH
 //     COMPLETED --> [*]

 // Export to Graphviz DOT
 String dot = StateMachineVisualizer.toDot(sm);
 System.out.println(dot);

 // Save to file
 Files.writeString(Path.of("workflow.mmd"), mermaid);
