Explicit representation of Haskell datatype information

data HType

A concrete representation of any Haskell type.

Constructors

Maybe HType

List HType

Tuple [HType]

Prim String String

separate Haskell name and XML name

String

Defined String [HType] [Constr]

A user-defined type has a name, a sequence of type variables, and a set of constructors. (The variables might already be instantiated to actual types.)

Instances

Eq HType

Defined in Text.XML.HaXml.TypeMapping

Methods

(==) :: HType -> HType -> Bool

(/=) :: HType -> HType -> Bool

Show HType

Defined in Text.XML.HaXml.TypeMapping

Methods

showsPrec :: Int -> HType -> ShowS

show :: HType -> String

showList :: [HType] -> ShowS

data Constr

A concrete representation of any user-defined Haskell constructor. The constructor has a name, and a sequence of component types. The first sequence of types represents the minimum set of free type variables occurring in the (second) list of real component types. If there are fieldnames, they are contained in the final list, and correspond one-to-one with the component types.

Constructors

Constr String [HType] [HType]

Instances

Eq Constr

Defined in Text.XML.HaXml.TypeMapping

Methods

(==) :: Constr -> Constr -> Bool

(/=) :: Constr -> Constr -> Bool

Show Constr

Defined in Text.XML.HaXml.TypeMapping

Methods

showsPrec :: Int -> Constr -> ShowS

show :: Constr -> String

showList :: [Constr] -> ShowS

Helper functions to extract type info as strings

showHType :: HType -> ShowS

showConstr :: Int -> HType -> String

Project the n'th constructor from an HType and convert it to a string suitable for an XML tagname.

Conversion from Haskell datatype to DTD

toDTD :: HType -> DocTypeDecl

toDTD converts a concrete representation of the Haskell type of a value (obtained by the method toHType) into a real DocTypeDecl. It ensures that PERefs are defined before they are used, and that no element or attribute-list is declared more than once.
