some :: MaybeS a -> MaybeS [a] #

many :: MaybeS a -> MaybeS [a] #

Unchanged !a 

data TreeApp e t Source #

Constructors

BinTree !e !t !t 
TipTree 

class IsBinTree t e | t -> e where Source #

Minimal complete definition

asBin, tip, bin, size

Methods

asBin :: t -> TreeApp e t Source #

tip :: t Source #

bin :: e -> t -> t -> t Source #

size :: t -> Int Source #

Instances
IsBinTree (MapF k2 a) (Pair k2 a) Source # 
Instance details

Defined in Data.Parameterized.Map

Methods

asBin :: MapF k2 a -> TreeApp (Pair k2 a) (MapF k2 a) Source #

tip :: MapF k2 a Source #

bin :: Pair k2 a -> MapF k2 a -> MapF k2 a -> MapF k2 a Source #

size :: MapF k2 a -> Int Source #

balanceL :: IsBinTree c e => e -> c -> c -> c Source #

balanceR :: IsBinTree c e => e -> c -> c -> c Source #

glue :: IsBinTree c e => c -> c -> c Source #

'glue l r' concatenates l and r.

It assumes that l and r are already balanced with respect to each other.

merge :: IsBinTree c e => c -> c -> c Source #

Concatenate two trees that are ordered with respect to each other.

filterGt :: IsBinTree c e => (e -> Ordering) -> c -> MaybeS c Source #

Returns only entries that are less than predicate with respect to the ordering and Nothing if no elements are discared.

filterLt :: IsBinTree c e => (e -> Ordering) -> c -> MaybeS c Source #

filterLt' k m returns submap of m that only contains entries that are smaller than k. If no entries are deleted then return Nothing.

insert :: IsBinTree c e => (e -> e -> Ordering) -> e -> c -> Updated c Source #

insert p m inserts the binding into m. It returns an Unchanged value if the map stays the same size and an updated value if a new entry was inserted.

delete Source #

Arguments

:: IsBinTree c e 
=> (e -> Ordering)

Predicate that returns whether the entry is less than, greater than, or equal to the key we are entry that we are looking for.

-> c 
-> MaybeS c 

union :: IsBinTree c e => (e -> e -> Ordering) -> c -> c -> c Source #

Union two sets

link :: IsBinTree c e => e -> c -> c -> c Source #

link is called to insert a key and value between two disjoint subtrees.

data PairS f s Source #

A Strict pair

Constructors

PairS !f !s
