Interface Formula

All Superinterfaces:

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

All Known Subinterfaces:

Formula.ArithmeticEquation, Formula.Equation

All Known Implementing Classes:

Formula.ArithmeticEquality, Formula.Conjunct, Formula.Disjunct, Formula.Equality, Formula.Inequality, Formula.Invoke, Formula.Is, Formula.Quantifier, Formula.Truth

public interface Formula
extends WyalFile.Expr

A special kind of expression which maintains a normal form representation. As such, formulae are not suitable for representing source-level syntax, as they do not faithfully retain relevant aspects, such as ordering, etc. Instead, they are used with the automated theorem prover for ensuring properties are correct.
