Class ArrayInitializer

  coins.ast.ASTree
      coins.ast.ASTList
          coins.ast.expr.ArrayInitializer

All Implemented Interfaces:

Expr, java.io.Serializable

public class ArrayInitializer

extends ASTList

implements Expr

An array of initial values.

For example, the initializing expression in the following code:

int a[] = { 1, 2, 3, 4 };

is represented as a linked-list of ConstantExpr objects representing 1, 2, 3, and 4.

A structure also takes an array of initial values:

struct price list[] = { { "book", 500 }, { "coffee", 200 } };

 
is represented as a linked-list of two ArrayInitializer
 objects.  Each of them contains a StringLiteral and a
 ConstantExpr.
