foldl' :: (a -> b -> a) -> a -> IntMap b -> acontainers Data.IntMap.Internal A strict version of foldl. Each application of the operator is evaluated before using the result in the next application. This function is strict in the starting value.
foldlWithKey :: (a -> Key -> b -> a) -> a -> IntMap b -> acontainers Data.IntMap.Internal Fold the keys and values in the map using the given left-associative binary operator, such that foldlWithKey f z == foldl (\z' (kx, x) -> f z' kx x) z . toAscList. For example,
keys = reverse . foldlWithKey (\ks k x -> k:ks) []
let f result k a = result ++ "(" ++ (show k) ++ ":" ++ a ++ ")" foldlWithKey f "Map: " (fromList [(5,"a"), (3,"b")]) == "Map: (3:b)(5:a)"foldlWithKey' :: (a -> Key -> b -> a) -> a -> IntMap b -> acontainers Data.IntMap.Internal A strict version of foldlWithKey. Each application of the operator is evaluated before using the result in the next application. This function is strict in the starting value.
foldl' :: (a -> b -> a) -> a -> IntMap b -> acontainers Data.IntMap.Lazy A strict version of foldl. Each application of the operator is evaluated before using the result in the next application. This function is strict in the starting value.
