Description | |||||||||||||||||||||||||
This module retained Haskell 98 compatability, but users who are happy with multi-parameter type classes should look towards Data.Generics.Biplate. The only function missing from Data.Generics.Uniplate is fold, as it can be constructed from children and has little meaning in a multi-typed setting. All operations, apart from childrenOn, descendOn and holesOn should perform identically to their non On counterparts. | |||||||||||||||||||||||||

module Data.Generics.UniplateStr | |||||||||||||||||||||||||
Types | |||||||||||||||||||||||||
type BiplateType from to = from -> (Str to, Str to -> from) | |||||||||||||||||||||||||
Return all the top most children of type to within from. If from == to then this function should return the root as the single child. | |||||||||||||||||||||||||
Operations | |||||||||||||||||||||||||
Queries | |||||||||||||||||||||||||
universeOn :: Uniplate to => BiplateType from to -> from -> [to] | |||||||||||||||||||||||||
childrenOn :: Uniplate to => BiplateType from to -> from -> [to] | |||||||||||||||||||||||||
Return the children of a type. If to == from then it returns the original element (in contrast to children) | |||||||||||||||||||||||||
