Interface Type

All Known Implementing Classes:

ArrayType, ClassSymbol, DataAggregateSymbol, FunctionType, InvalidType, PointerType, PrimitiveType, TypeAlias

public interface Type

This interface is a tag that indicates the implementing object is a kind of type. Every type knows its name. In languages like C where we need a tree-like structure to represent a type, one could return a string representation as the name. The types are typically things like struct or classes and primitive types, as well as the type trees used for languages like C.

Method Summary

Modifier and Type	Method and Description
String	getName()
int	getTypeIndex() It is useful during type computation and code gen to assign an int index to the primitive types and possibly user-defined types like structs and classes.

Method Detail

getName

String getName()

getTypeIndex

int getTypeIndex()

It is useful during type computation and code gen to assign an int index to the primitive types and possibly user-defined types like structs and classes.

Returns:

Return 0-indexed type index else -1 if no index.
