mapBodyM :: Monad m => (body0 > m body1) > T time body0 > m (T time body1)  Source 


mapTimeM :: Monad m => (time0 > m time1) > T time0 body > m (T time1 body)  Source 


getTimes :: T time body > [time]  Source 


getBodies :: T time body > [body]  Source 




merge :: (Ord time, Ord body) => T time body > T time body > T time body  Source 


mergeBy :: Ord time => (body > body > Bool) > T time body > T time body > T time body  Source 


insert :: (Ord time, Ord body) => time > body > T time body > T time body  Source 


insertBy :: Ord time => (body > body > Bool) > time > body > T time body > T time body  Source 


moveForward :: (Ord time, Num time) => T time (time, body) > T time body  Source 

Move events towards the front of the event list.
You must make sure, that no event is moved before time zero.
This works only for finite lists.


decreaseStart :: (Ord time, Num time) => time > T time body > T time body  Source 


delay :: (Ord time, Num time) => time > T time body > T time body  Source 




partition :: (body > Bool) > T time body > (T time body, T time body)  Source 


slice :: (Eq a, Num time) => (body > a) > T time body > [(a, T time body)]  Source 


foldr :: (time > a > b) > (body > b > a) > a > T time body > b  Source 


mapMaybe :: Num time => (body0 > Maybe body1) > T time body0 > T time body1  Source 





sort sorts a list of coinciding events,
that is all events but the first one have time difference 0.
normalize sorts all coinciding events in a list
thus yielding a canonical representation of a time ordered list.




collectCoincident :: Eq time => T time body > T time [body]  Source 




mapCoincident :: (Ord time, Num time) => ([a] > [b]) > T time a > T time b  Source 

Apply a function to the lists of coincident events.


append :: (Ord time, Num time) => T time body > T time body > T time body  Source
