Class Summary

Class	Description
CatMaybes<A>	Given an Iterable<Maybe<A>>, return an Iterable<A> of only the present values.
Coalesce<L,R>	Fold an Iterable<Either<L, R>> into an Either<Iterable<L>, Iterable<R>>, preserving all results of the side that's returned.
Constantly<A,B>	A function that takes two arguments and always returns the first argument.
Cycle<A>	Given an Iterable, return an infinite Iterable that repeatedly cycles its elements, in order.
Distinct<A>	Return an Iterable of the distinct values from the given input Iterable.
Downcast<A extends B,B>	Covariantly cast a value of type B to a value of subtype A.
Empty<A>	A predicate that returns true if as is empty; false otherwise.
Flatten<A>	Given a nested Iterable of Iterables, return a lazily flattening Iterable of the nested elements.
Force<A>	Deprecated. in favor of traversing into an IO and running it
Head<A>	Retrieve the head element of an Iterable, wrapped in an Maybe.
Id<A>	The identity function.
Init<A>	Given an Iterable<A>, produce an Iterable<A> of all elements but the last one.
Inits<A>	Given an Iterable<A>, produce an Iterable<Iterable<A>>, representing all of the subsequences of initial elements, ordered by size, starting with the empty Iterable.
Last<A>	Retrieve the last element of an Iterable, wrapped in a Maybe.
Magnetize<A>	Magnetize an Iterable using value equality as the magnetizing function.
Not<A>	Negate a predicate function.
Occurrences<A>	Given an Iterable<A>, return a Map<A, Long> representing each unique element in the Iterable paired with its number of occurrences.
Repeat<A>	Given a value, return an infinite Iterable that repeatedly iterates that value.
Reverse<A>	Given an Iterable, return a reversed representation of that Iterable.
Size
Sort<A extends java.lang.Comparable<A>>	Given an Iterable of Comparable elements, return a List of the sorted elements.
Tail<A>	Returns the tail of an Iterable; the is, an Iterable of all the elements except for the head element.
Tails<A>	Given an Iterable<A>, produce an Iterable<Iterable<A>>, representing all of the subsequences of tail elements, ordered by size, starting with the full Iterable.
Uncons<A>	Destructure an Iterable into a Tuple2 of its head and tail, wrapped in an Maybe.
Upcast<A extends B,B>	Upcast a value of type B to a value of type A that B extends.
