@hackage RBTree0.0.5

Pure haskell Red-Black-Tree implemetation

Pure haskell implementation from Wu Xingbo (wuxb45@gmail.com) 2011

WARNING:This Implementation mainly concerns about functionality. After that I will improve the performence and efficiency.

to Build & Install for yourself: shell> runhaskell Setup.lhs configure --user shell> runhaskell Setup.lhs build shell> runhaskell Setup.lhs install

on any problem, you may try this: shell> runhaskell Setup.lhs register

for system, replace '--user' with '--ghc'

changelog (0.0.2): add bangpatterns to some data field. add ghc optimization flags to .cabal be careful of memory usage. insert 10MiB Int values takes 3 seconds and 800MiB memory space.

changelog (0.0.3): add function "searchFast". rename 'remove*' functions to 'delete*'s.

changelog (0.0.4): add functions for search min/max value. add functions for search for a interval that the two values in the tree holds the given value modified search functions can accept a 'compare' function like: (b -> a -> Ordering) search for an 'a' by first key of a (RBTree (a,b)) canbe done in such way:

b :: Int b = 10 t :: RBTree (Int,String) t = insertOrdList emptyRB [(1,"hello"), (2,"world")] result :: (Int,String) result = search (\k (k',_) -> k compare k') t 2 it returns "Just (2,"world")"

changelog (0.0.5): add three operators for insert/delete/search. updates the comments to co-op with haddock. delete the RBTreeTest module. clean is better.
