- Gesture Sets
- collections of gesture recognizers that interface between the gesture recognizers and the application
- Gesture buckets
- lists of gesture recognizers that have not yet been processed
- Gesture timers
- data type definitions and functions for manipulating timers used for determining the time elapsed between touches or the length of a touch
- Event lists
- data type definitions and functions for lists of mtouch events to be processed by the gesture sets
- Data types and Helper functions
