Class Aggregate

java.lang.Object
  coins.ast.ASTree
      coins.ast.Aggregate

All Implemented Interfaces:

java.io.Serializable, Stmnt

Direct Known Subclasses:

Struct, Union

public abstract class Aggregate

extends ASTree

implements Stmnt

Declaration of a struct/union type. If the declaration appears in a type name, the type name is decomposed into the declaration and a reference to the declared structure/union.

For example, a variable declaration:

struct Point {
     int x, y;
     struct Color { int color; } c;
 } p;

is decomposed into three declarations.

struct Color { int color; };    => ast.Struct object
 struct Point {                           => ast.Struct object
     int x, y;
     struct Color c;
 };
 struct Point p;                          => ast.Declarator object
 

The struct declaration never appears as part of a type name.
