Package kodkod.ast.visitor Description

Contains visitors for Kodkod formulas, expressions, and integer expressions.

Package Specification

Provides two interfaces for traversing the Kodkod AST using the visitor pattern. A VoidVisitor visits the nodes but returns no values. A ReturnVisitor can be parametrized to return values of specific types for Decls, Expression, IntExpression, and Formula nodes.

Several skeletal implementations of the VoidVisitor and ReturnVisitor interfaces are also provided. These traverse the AST in a depth-first manner and optionally cache the results of visiting specified nodes. The caching functionality makes it convenient to implement visitors that visit shared nodes only once.
