sam :: Time -> Time Source #

The sam (start of cycle) for the given time value

toTime :: Real a => a -> Rational Source #

Turns a number into a (rational) time value. An alias for toRational.

fromTime :: Fractional a => Time -> a Source #

Turns a (rational) time value into another number. An alias for fromRational.

nextSam :: Time -> Time Source #

The end point of the current cycle (and starting point of the next cycle)

cyclePos :: Time -> Time Source #

The position of a time value relative to the start of its cycle.

hull :: Arc -> Arc -> Arc Source #

convex hull union

subArc :: Arc -> Arc -> Maybe Arc Source #

subArc i j is the timespan that is the intersection of i and j. intersection The definition is a bit fiddly as results might be zero-width, but not at the end of an non-zero-width arc - e.g. (0,1) and (1,2) do not intersect, but (1,1) (1,1) does.

sect :: Arc -> Arc -> Arc Source #

Simple intersection of two arcs

timeToCycleArc :: Time -> Arc Source #

The arc of the whole cycle that the given time value falls within

cycleArc :: Arc -> Arc Source #

Shifts an arc to the equivalent one that starts during cycle zero

cyclesInArc :: Integral a => Arc -> [a] Source #

A list of cycle numbers which are included in the given arc

cycleArcsInArc :: Arc -> [Arc] Source #

A list of arcs of the whole cycles which are included in the given arc

arcCycles :: Arc -> [Arc] Source #

Splits the given Arc into a list of Arcs, at cycle boundaries.

arcCyclesZW :: Arc -> [Arc] Source #

Like arcCycles, but returns zero-width arcs

mapCycle :: (Time -> Time) -> Arc -> Arc Source #

Similar to fmap but time is relative to the cycle (i.e. the sam of the start of the arc)

isIn :: Arc -> Time -> Bool Source #

isIn a t is True if t is inside the arc represented by a.
