transform :: Uniplate on => (on -> on) -> on -> onuniplate Data.Generics.Uniplate.DataOnly Transform every element in the tree, in a bottom-up manner. For example, replacing negative literals with literals:
negLits = transform f where f (Neg (Lit i)) = Lit (negate i) f x = x
transformBi :: Biplate from to => (to -> to) -> from -> fromuniplate Data.Generics.Uniplate.DataOnly No documentation available.
transformBiM :: (Monad m, Applicative m, Biplate from to) => (to -> m to) -> from -> m fromuniplate Data.Generics.Uniplate.DataOnly No documentation available.
transformBis :: Data a => [[Transformer]] -> a -> auniplate Data.Generics.Uniplate.DataOnly Apply a sequence of transformations in order. This function obeys the equivalence:
transformBis [[transformer f],[transformer g],...] == transformBi f . transformBi g . ...
Each item of type [Transformer] is applied in turn, right to left. Within each [Transformer], the individual Transformer values may be interleaved. The implementation will attempt to perform fusion, and avoid walking any part of the data structure more than necessary. To further improve performance, you may wish to partially apply the first argument, which will calculate information about the relationship between the transformations.transformM :: (Monad m, Applicative m, Uniplate on) => (on -> m on) -> on -> m onuniplate Data.Generics.Uniplate.DataOnly Applicative variant of transform
