    Description
    DEFAULT
    No additional hint.
    QUALITY
    A hint to tell the bitmap caching mechanism that this node should appear on screen at the highest visual quality.
    ROTATE
    A hint to tell the bitmap caching mechanism that if the node is rotated, it is acceptable to paint it by rotating the cached bitmap (rather than re-rendering the node).
    SCALE
    A hint to tell the bitmap caching mechanism that if the node is scaled up or down, it is acceptable to paint it by scaling the cached bitmap (rather than re-rendering the node).
    SCALE_AND_ROTATE
    A hint to tell the bitmap caching mechanism that if the node is scaled and/or rotated, it is acceptable to paint it by scaling and/or rotating the cached bitmap (rather than re-rendering the node).
    SPEED
    A hint to tell the bitmap caching mechanism that this node is animating, and should be painted from the bitmap cache whenever possible in order to maintain smooth animation.

    • DEFAULT

      public static final CacheHint DEFAULT
      No additional hint. The system will determine the best use of the bitmap cache.

    • SPEED

      public static final CacheHint SPEED
      A hint to tell the bitmap caching mechanism that this node is animating, and should be painted from the bitmap cache whenever possible in order to maintain smooth animation. The trade-off is that this may result in decreased visual quality.

    • QUALITY

      public static final CacheHint QUALITY
      A hint to tell the bitmap caching mechanism that this node should appear on screen at the highest visual quality. The cached bitmap will only be used when it will not degrade the node's appearance on screen.

      The trade-off is that animations may cause subtle variations in the way that a node would be rendered, and so a node with a cacheHint of QUALITY may be required to re-render a node even when such subtle variations would not be visible in the midst of an animation. As such, a node with a cacheHint of QUALITY will often benefit from having its cacheHint replaced with a more permissive value (such as SPEED) during the period of the animation.

    • SCALE

      public static final CacheHint SCALE
      A hint to tell the bitmap caching mechanism that if the node is scaled up or down, it is acceptable to paint it by scaling the cached bitmap (rather than re-rendering the node).

    • ROTATE

      public static final CacheHint ROTATE
      A hint to tell the bitmap caching mechanism that if the node is rotated, it is acceptable to paint it by rotating the cached bitmap (rather than re-rendering the node).

    • SCALE_AND_ROTATE

      public static final CacheHint SCALE_AND_ROTATE
      A hint to tell the bitmap caching mechanism that if the node is scaled and/or rotated, it is acceptable to paint it by scaling and/or rotating the cached bitmap (rather than re-rendering the node).

  • Method Details

    • values

      public static CacheHint[] values()
      Returns an array containing the constants of this enum class, in the order they are declared.
      Returns:
      an array containing the constants of this enum class, in the order they are declared

    • valueOf

      public static CacheHint valueOf(String name)
      Returns the enum constant of this class with the specified name. The string must match exactly an identifier used to declare an enum constant in this class. (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:
      IllegalArgumentException - if this enum class has no constant with the specified name
      NullPointerException - if the argument is null
