Unions of Containers

class HasUnion f where Source

A Container suitable for the Union Monoid Methods empty :: f Source union :: f -> f -> f Source Instances HasUnion IntSet Eq a => HasUnion ([] a) HasUnion (IntMap a) Ord a => HasUnion (Set a) Ord k => HasUnion (Map k a)

newtype Union f Source

The Monoid (union,empty) Constructors Union getUnion :: f Instances Functor Union Pointed Union Copointed Union HasUnion f => Reducer f (Union f) Eq f => Eq (Union f) Ord f => Ord (Union f) Read f => Read (Union f) Show f => Show (Union f) HasUnion f => Monoid (Union f)

Unions of Containers of Monoids

class Functor f => HasUnionWith f where Source

Polymorphic containers that we can supply an operation to handle unions with Methods unionWith :: (a -> a -> a) -> f a -> f a -> f a Source emptyWith :: f a Source Instances HasUnionWith IntMap Ord k => HasUnionWith (Map k)

newtype UnionWith f m Source

The Monoid ('unionWith mappend',empty) for containers full of monoids. Constructors UnionWith getUnionWith :: f m Instances (HasUnionWith f, Ord r, Eq r, RightSemiNearRing r) => RightModule r (UnionWith f r) (HasUnionWith f, Ord r, Eq r, RightSemiNearRing r) => LeftModule r (UnionWith f r) (HasUnionWith f, Ord r, Eq r, RightSemiNearRing r) => Module r (UnionWith f r) Monad f => Monad (UnionWith f) Functor f => Functor (UnionWith f) Pointed f => Pointed (UnionWith f) (HasUnionWith f, Monoid m) => Reducer (f m) (UnionWith f m) Eq (f m) => Eq (UnionWith f m) Ord (f m) => Ord (UnionWith f m) Read (f m) => Read (UnionWith f m) Show (f m) => Show (UnionWith f m) (HasUnionWith f, Monoid m) => Monoid (UnionWith f m)
