Class WyalFile.Expr.ArrayUpdate

java.lang.Object

wybs.lang.SyntacticElement.Impl

wybs.util.AbstractSyntacticItem

wyal.lang.WyalFile.Expr.Operator

wyal.lang.WyalFile.Expr.ArrayUpdate

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.ArrayUpdate
extends WyalFile.Expr.Operator

Represents an array update expression of the form "arr[e1:=e2]" where arr is the source array, e1 the subscript expression and e2 is the value expression. This returns a new array which is equivalent to arr but where the element determined by e1 has the value resulting from e2.
