## Detailed Description

class `HBhvInterpolatorAttSwitch` : public HBhvInterpolator

  The HBhvInterpolatorAttSwitch class switches attributes on segments.

  HBhvInterpolatorAttSwitch uses HC_Style_Segment() to change the attribute on the segments specified in the keyframe list.

  Public Functions

  `HBhvInterpolatorAttSwitch`(HBhvAnimation *animation = 0, char const *name = 0)

    Constructs an HBhvInterpolatorAttSwitch object.

    Parameters: | animation – The animation that this interpolator belongs to. name – The name of the interpolator.

  virtual char const *`GetType`()

    Returns: | The type of the interpolator which is ‘AttSwitch’.

  virtual HBhvInterpolator *`CreateInstance`(HBhvAnimation *ainst)

    In special cases, you may want an interpolator that references this interpolator without changing it. Use this method to create the new interpolator passing a pointer to the animation that you want it to be associated with.

    Parameters: | ainst – The animation instance that this interpolator is associated with.
    Returns: | The newly created interpolator that references this interpolator.

  inline void `Insert`(char const *t, int l = 0)

    This method creates a new keyframe with the passed style segment path t and then inserts it after the passed position l into the keyframe array.

    Parameters: | t – The style segment path for the new keyframe. l – The array position to insert item after.

  inline void `Replace`(char const *spath, int l)

    Replaces the item at the given position in the keyframe array with a new keyframe that was created with the passed style segment path spath.

    Parameters: | spath – The style segment path for the new replacement keyframe. l – The array position to replace.

  virtual void `Serialize`(HUtilityXMLGenerator *xmlgen)

    Writes XML data to a buffer using the passed XML generator.

  virtual void `Interpolate`(int keyframe, float fraction)

    Performs interpolation on the animation target.

    Parameters: | keyframe – The reference keyframe for this interpolation. fraction – The fraction value from the specified keyframe to the next keyframe. The value is from 0 to 1.

  Public Static Functions

  static void *`XMLCallback`(HUtilityXMLTag *xt, bool open, void *m_pExtraData)

    This is XML read callback which parses XML data and then populates the member variables with the associated values.
