Enum Screen.RefreshType

  • All Implemented Interfaces:
    java.io.Serializable, java.lang.Comparable<Screen.RefreshType>
    Enclosing interface:
    Screen

    public static enum Screen.RefreshType
    extends java.lang.Enum<Screen.RefreshType>
    This enum represents the different ways a Screen can refresh the screen, moving the back-buffer data into the front-buffer that is being displayed.
    • Enum Constant Summary

      Enum Constants 
      Enum Constant Description
      AUTOMATIC
      Using automatic mode, the Screen will make a guess at which refresh type would be the fastest and use this one.
      COMPLETE
      In RefreshType.COMPLETE mode, the screen will send a clear command to the terminal, then redraw the whole back-buffer line by line.
      DELTA
      In RefreshType.DELTA mode, the Screen will calculate a diff between the back-buffer and the front-buffer, then figure out the set of terminal commands that is required to make the front-buffer exactly like the back-buffer.

      • AUTOMATIC

        public static final Screen.RefreshType AUTOMATIC
        Using automatic mode, the Screen will make a guess at which refresh type would be the fastest and use this one.
      • DELTA

        public static final Screen.RefreshType DELTA
        In RefreshType.DELTA mode, the Screen will calculate a diff between the back-buffer and the front-buffer, then figure out the set of terminal commands that is required to make the front-buffer exactly like the back-buffer. This normally works well when you have modified only parts of the screen, but if you have modified almost everything it will cause a lot of overhead and you should use RefreshType.COMPLETE instead.
      • COMPLETE

        public static final Screen.RefreshType COMPLETE
        In RefreshType.COMPLETE mode, the screen will send a clear command to the terminal, then redraw the whole back-buffer line by line. This is more expensive than RefreshType.COMPLETE, especially when you have only touched smaller parts of the screen, but can be faster if you have modified most of the content, as well as if you suspect the screen's internal front buffer is out-of-sync with what's really showing on the terminal (you didn't go and call methods on the underlying Terminal while in screen mode, did you?)

      • values

        public static Screen.RefreshType[] values()
        Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:
        for (Screen.RefreshType c : Screen.RefreshType.values())
            System.out.println(c);
        
        Returns:
        an array containing the constants of this enum type, in the order they are declared
      • valueOf

        public static Screen.RefreshType valueOf​(java.lang.String name)
        Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)
        Parameters:
        name - the name of the enum constant to be returned.
        Returns:
        the enum constant with the specified name
        Throws:
        java.lang.IllegalArgumentException - if this enum type has no constant with the specified name
        java.lang.NullPointerException - if the argument is null
