Class WyalFile.Expr.ArrayGenerator

java.lang.Object

wybs.lang.SyntacticElement.Impl

wyal.heap.AbstractSyntacticItem

wyal.lang.WyalFile.Expr.Operator

wyal.lang.WyalFile.Expr.ArrayGenerator

All Implemented Interfaces:

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

Enclosing interface:

WyalFile.Expr

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

Represents an array generator expression of the form "[e1;e2]" where e1 is the element expression and e2 is the length expression. This returns a new array whose length is determined by e2 and where every element has contains the value determined by e1.
