Description

Static IOArray-based Graphs

Synopsis

data SGr a b = SGr (GraphRep a b) type GraphRep a b = (Int, Array Node (Context' a b), IOArray Node Bool) type Context' a b = Maybe (Adj b, a, Adj b) type USGr = SGr () () defaultGraphSize :: Int emptyN :: Int -> IO (SGr a b) removeDel :: IOArray Node Bool -> Adj b -> IO (Adj b)

Graph Representation

data SGr a b

Constructors SGr (GraphRep a b) Instances GraphM IO SGr (Show a, Show b) => Show (IO (SGr a b)) (Show a, Show b) => Show (SGr a b)

type GraphRep a b = (Int, Array Node (Context' a b), IOArray Node Bool)

type Context' a b = Maybe (Adj b, a, Adj b)

type USGr = SGr () ()

defaultGraphSize :: Int

emptyN :: Int -> IO (SGr a b)

Utilities

removeDel :: IOArray Node Bool -> Adj b -> IO (Adj b)

filter list (of successors/predecessors) through a boolean ST array representing deleted marks
