wybs.lang.SyntacticElement.Impl

wybs.util.AbstractSyntacticItem

wyal.lang.WyalFile.Expr.Quantifier

All Implemented Interfaces:

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

Direct Known Subclasses:

Formula.Quantifier, WyalFile.Expr.ExistentialQuantifier, WyalFile.Expr.UniversalQuantifier

Enclosing interface:

WyalFile.Expr

public abstract static class WyalFile.Expr.Quantifier
extends wybs.util.AbstractSyntacticItem
implements WyalFile.Expr

Represents an abstract quantified expression of the form "forall(T v1, ... T vn).e" or "exists(T v1, ... T vn).e" where T1 v1 ... Tn vn are the quantified variable declarations and e is the body.
