Detailed Description

Helper class that accumulates move (touch events) within some time period (time defined FIFO queue). It helps to MoveHandler determine of move vector when drag gesture ends. It is used for animate move momentum.

Constructor & Destructor Documentation

MoveAccumulator()

osmscout::MoveAccumulator::MoveAccumulator ( int  memory = 100, double  factor = 4, double  vectorLengthTreshold = 5  )

Parameters

memory	- in milliseconds for finger position points
factor	- momentum movement length (vector returned from collect method) will be equal to recorded length * factor
vectorLengthTreshold	- movement (between two points) have to be longer than treshold (in pixels) for change move vector
