Interface NominalTypeBuilder

All Known Implementing Classes:

NominalTypeBuilderOti

public interface NominalTypeBuilder

Builder interface for declaring properties on class-like (nominal) types. Nominal types consist primarily of three separate object types, which may each have their own properties declared on them separately: (1) the constructor function, (2) the instance type, and (3) the prototype object. This interface is used during the first part of type checking, while the type checker builds up the set of known types. At this stage, not all types actually exist in a usable form: specifically, NTI cannot express the type of a prototype object until immediately before the owner type is frozen. Thus, this interface serves as a placeholder to allow operating on (i.e. both assigning properties to, and referencing the yet-to-exist type) these not-yet-available types.

Method Summary

Modifier and Type	Method and Description
FunctionTypeI	constructor() Returns the constructor as a TypeI.
void	declareConstructorProperty(java.lang.String name, TypeI type, Node defSite) Declares a static property on the nominal type's constructor.
void	declareInstanceProperty(java.lang.String name, TypeI type, Node defSite) Declares an instance property on the nominal type.
void	declarePrototypeProperty(java.lang.String name, TypeI type, Node defSite) Declares a property on the nominal type's prototype.
ObjectTypeI	instance() Returns the instance type as a TypeI.
ObjectTypeI	prototypeOrInstance() Returns the type of the prototype object (OTI) or instance (NTI).
NominalTypeBuilder	superClass() Returns a NominalTypeBuilder for this type's superclass.
