sealed abstract class Defn extends Positioned

A definition in NIR.

A definition in NIR.

Programs in NIR are represented as a sequence of definitions denoting types, methods and fields. Definitions fall into two categories:

  • Top-level definitions: these represent classes, modules, traits, or global variables and constants.
  • Member definitions: these represent fields or methods.

Classes and modules inherit from a single parent with the exception of java.lang.Object, which sits at the top of the hierarchy. They may additionally implement traits.

Definitions may also carry attributes providing further information about their semantics (e.g., whether a method may be inlined). Attributes are also used to mark special-purpose definitions, such as stubs, proxies and FFIs.

Types

type LocalName = String

The name of a variable in program sources.

The name of a variable in program sources.

type LocalNames = Map[Local, LocalName]

A map from SSA identifier to its name in program sources.

A map from SSA identifier to its name in program sources.

Local variables get lowered to an static assignment that is assigned to a unique identifier in the context of its definition. Instances of this type are used to maintain the correspondance between an SSA ID and its corresponding name in program sources.
