Description

A model for simple algebraic data types.

Synopsis

Model

data TypeModel adtName consName inRef exRef Source #

The complete model of a type, a reference to the type plus its environment:

  • adtName: type used to represent the name of a data type
  • consName: type used to represent the name of a constructor
  • inRef: type used to represent a reference to a type or a type variable inside the data type definition (for example HTypeRef)
  • exRef: type used to represent a reference to a type in the type name (for example QualName)

Constructors

TypeModel 

Fields

  • typeName :: Type exRef

    The type application corresponding to the type

  • typeEnv :: TypeEnv adtName consName inRef exRef

    The environment in which the type is defined

data ConTree name ref Source #

Constructors are assembled in a binary tree

Constructors

Con 

Fields

  • constrName :: name

    The constructor name, unique in the data type

  • constrFields :: Fields name ref

    Constructor fields, they can be either unnamed (Left case) or named (Right case) If they are named, they must all be named

ConTree (ConTree name ref) (ConTree name ref)

Constructor tree.

Constructors are disposed in an optimally balanced, right heavier tree:

For example, the data type:

data N = One | Two | Three | Four | Five

Would have its contructors ordered in the following tree:

         |
    |            |
 One Two   Three   |
               Four Five

To get a list of constructor in declaration order, use constructors
