Detailed Description

The state of one drag on the group volume slider.

It lives outside the row's listener: the row is rebound while the finger is down (a status poll, a change of the group), and a new listener must go on with the drag it did not see begin.

The members' levels at the start are read from the devices after the touch began; the movement until they are there is only remembered and then applied once. A drag that ended or was replaced by a newer one does not apply late reads. Thread-safe: the touch comes on the main thread, the levels on a worker.

synchronized Map< String, Integer > de.yaacc.yxc.YxcGroupDrag.levelsArrived	(	int	dragId,
		Map< String, Integer >	read )

The start levels of drag dragId were read.

Returns

the levels to send now (for the latest position), or null if that drag is no longer the current one

moved()

synchronized Map< String, Integer > de.yaacc.yxc.YxcGroupDrag.moved
