Method Detail

• get

  public final String get()

  Description copied from interface: UiStyles
  This method gets the style(s) (also called style-name(s)) of this object. The style defines aspects for the appearance (look & feel) of a UI element when displayed to the user.
  If you are familiar with web-technology just think of this as the class attribute of HTML elements that are then configured via some cascading style sheet (CSS).
  The following situations can be distinguished:

  • no style
    The empty string is returned.
  • single style
    The name of that single style is returned. The result does NOT contain any whitespace.
  • multiple styles
    The list of individual styles are separated by whitespaces in the result.

  Each individual style has to match UiStyles.PATTERN_SINGLE. Any number of styles or in other words the result of this has to match UiStyles.PATTERN_MULTIPLE. The first style is called the primary style.
