Functions to work with them

Read functions

readMaybeEC :: Int -> String -> Maybe EncodedCnstrs

Inspired by the: https://hackage.haskell.org/package/base-4.14.0.0/docs/Data-Maybe.html Is provided here as a more general way to read the String into a EncodedCnstrs than more restricted but safer readMaybeECG. It is up to user to check whether the parameters are in the correct form, the function does not do the full checking. For phonetic-languages applications, it is better to use readMaybeECG function instead.

readMaybeECG :: Int -> String -> Maybe EncodedCnstrs

A safer variant of the readMaybeEC more suitable for applications, e. g. for phonetic-languages series of packages.

Process-encoding functions

decodeConstraint1 :: (InsertLeft t (Array Int Int), Monoid (t (Array Int Int))) => EncodedCnstrs -> t (Array Int Int) -> t (Array Int Int)

Must be applied to the correct array of permutation indeces. Otherwise, it gives runtime error (exception). All the integers inside the EncodedCnstrs must be in the range [0..n] where n corresponds to the maximum element in the permutation Array Int Int. Besides, n is (probably must be) not greater than 6.

decodeLConstraints :: (InsertLeft t (Array Int Int), Monoid (t (Array Int Int))) => [EncodedCnstrs] -> t (Array Int Int) -> t (Array Int Int)

Must be applied to the correct array of permutation indeces. Otherwise, it gives runtime error (exception). All the integers inside the EncodedCnstrs must be in the range [0..n] where n corresponds to the maximum element in the permutation Array Int Int. Besides, n is (probably must be) not greater than 6.

Modifiers and getters

getIEl :: EncodedCnstrs -> Int

Works only with the correctly defined argument though it is not checked. Use with this caution.

setIEl :: Int -> EncodedCnstrs -> EncodedCnstrs

Works only with the correctly defined arguments though it is not checked. Use with this caution.
