Interface PAGesture

All Known Implementing Classes:
GestureSchedule, PACurveMaker
public interface PAGesture
PAGesture provides a interface for "gesture" defined by:
  1. a list of points and
  2. a list of time offsets where
  3. both lists have the same cardinality and
  4. time offsets are monotonically non-decreasing. In addition,
  5. the time list is expected (but not required) to start with a first element 0.

Absolute time of gesture creation can be returned from getStartTimeMs(), possibly as millis from application start.

Gestures are often captured from GUI interaction, as is the case with PACurveMaker. PAGesture opens the way to use many different sources for generating gestures. "Gesture" is a core concept in the PixelAudio library, implemented by PACurveMaker, in particular.
