Principles

• No code in constructors
• No mutable objects
• No static
• No public methods without contract (interface)
• No implementation inheritance
• No returns null (Optional)

Example usage

final class Example {

  void clearKnownCommands() {
    new ClassOf<>(Bukkit.getServer())
      .methodByName("getCommandMap")
      .flatMap(refMethod -> refMethod.of(Bukkit.getServer()).call().map(o -> o instanceof CommandMap))
      .ifPresent(commandMap -> new ClassOf<>(commandMap)
        .methodByName("clearCommands")
        .ifPresent(clearCommandsMethod ->
          clearCommandsMethod.of(commandMap).call()));
  }
