1 dimensional Intervals

data Interval a r Source #

An Interval is essentially a Range but with possible payload

We can think of an interval being defined as:

>>> data Interval a r = Interval (EndPoint (r :+ a)) (EndPoint (r :+ a))

Working with intervals

inInterval :: Ord r => r -> Interval a r -> Bool Source #

Test if a value lies in an interval. Note that the difference between inInterval and inRange is that the extra value is *not* used in the comparison with inInterval, whereas it is in inRange.

shiftLeft' :: Num r => r -> Interval a r -> Interval a r Source #

Shifts the interval to the left by delta

asProperInterval :: Ord r => Interval p r -> Interval p r Source #

Makes sure the start and endpoint are oriented such that the starting value is smaller than the ending value.

flipInterval :: Interval a r -> Interval a r Source #

Flips the start and endpoint of the interval.
