    • getStateStyle

      public String getStateStyle(Map<String,String> md)
      In Plant UML state diagrams, if we have to change the style for a state then we have to write a construct that looks like below:
      state A #White##[bold]Black

      In this example, White is the background color and Black is the border color. Bold is the line style of the border line.

      This method emits the styling string (in the form "#White##[bold]Black" or a blank string if no styling string is specified for the given metadata.
      Parameters:
      md - metadata
      Returns:
      a styling string of the form indicated above.

    • getConnectionStyle

      public String getConnectionStyle(Map<String,String> md)
      In Plant UML state diagrams, if we have to change the style for a connection between two states, we have to write a construct that looks like below:
      A -[thickness=x,#white]-> B
      This method emits the styling string (in the form "[thickness=2,#white]" or a blank string if no styling string is specified for the given metadata.
      Parameters:
      md - metadata
      Returns:
      a styling string of the form indicated above.

    • printEventText

      public String printEventText(String text, Map<String,String> md)
      Renders the text with optional style.
      Parameters:
      text - the event to render
      Returns:
      the decorated eventId. If a metadata called label is present, then the text returned is the value of the label.
