uniplate-1.6.1: Help writing simple, concise and fast generic operations.

Data.Generics.Biplate

Contents

Description

DEPRECATED: Use Data.Generics.Uniplate.Operations instead.

Requires multi-parameter type classes, so is no longer Haskell 98. These operations are easier to use and construct than the equivalent Data.Generics.UniplateStrOn methods, but perform the same operation.

It is recommended that instead of importing this module, you import one of the following modules, to construct instances:

Synopsis

Documentation

The Class

class Uniplate to => Biplate from to whereSource

Children are defined as the top-most items of type to starting at the root.

Methods

biplate :: BiplateType from toSource

Instances

(Typeable a, Typeable b, Uniplate b, PlateAll a b) => Biplate a b 
(Data a, Data b, Uniplate b, Typeable a, Typeable b) => Biplate a b 

biplateList :: Biplate from to => from -> ([to], [to] -> from)Source

Compatibility method, for direct users of the biplate function
