java.lang.Object

wybs.lang.SyntacticElement.Impl

wyal.heap.AbstractSyntacticItem

wyal.lang.WyalFile.Expr.Constant

All Implemented Interfaces:

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

Direct Known Subclasses:

Formula.Truth

Enclosing interface:

WyalFile.Expr

public static class WyalFile.Expr.Constant
extends AbstractSyntacticItem
implements WyalFile.Expr
