Graphics.QML.Marshal

Type classs and instances for marshalling values between Haskell and QML.

Documentation

class Marshal t where

The class Marshal allows Haskell values to be marshalled to and from the QML environment.

Associated Types

type MarshalMode t

The MarshalMode associated type parameter specifies the type of marshalling functionality offered by the instance.

Methods

marshaller :: Marshaller t (MarshalMode t)

Yields the Marshaller for the type t.

Instances

Marshal Double

Marshal Int

Marshal Int32

Marshal String

Marshal ()

Marshal AnyObjRef

Marshal Text

class MarshalBase m => MarshalToValRaw m

Class for MarshalModes which support marshalling Haskell-to-QML.

Instances

MarshalToValRaw ValFnRetVoid

MarshalToValRaw ValBidi

MarshalToValRaw (ValObjBidi a)

class MarshalToValRaw m => MarshalToVal m

data ValBidi

MarshalMode for built-in data types.

Instances

MarshalToHs (ValObjBidi a)

MarshalToObj (ValObjBidi a)

MarshalFromObj (ValObjBidi a)

data ValObjToOnly a

MarshalMode for object types, operating only in the QML-to-Haskell direction.

Instances

MarshalToHs (ValObjToOnly a)

MarshalFromObj (ValObjToOnly a)

type ThisObj tt = ModeObj (MarshalMode tt)

Type function yielding the object type speficied by a given marshallable type tt.

data family Marshaller t m

Encapsulates the functionality to needed to implement an instance of Marshal so that such instances can be defined without access to implementation details.
