Class WyalFile.Expr.ArrayAccess

java.lang.Object

wybs.lang.SyntacticElement.Impl

wybs.util.AbstractSyntacticItem

wyal.lang.WyalFile.Expr.Operator

wyal.lang.WyalFile.Expr.ArrayAccess

All Implemented Interfaces:

Cloneable, Comparable<wybs.lang.SyntacticItem>, WyalFile.Expr, WyalFile.Stmt, wybs.lang.SyntacticElement, wybs.lang.SyntacticItem

Enclosing interface:

WyalFile.Expr

public static class WyalFile.Expr.ArrayAccess
extends WyalFile.Expr.Operator

Represents an array access expression of the form "arr[e]" where arr is the source array and e the subscript expression. This returns the value held in the element determined by e.
