## Uses of Interface
org.modeshape.jcr.query.model.Visitable

- Packages that use Visitable
  Package | Description
  --- | ---
  org.modeshape.jcr.query.model | The Abstract Query Model is a vocabulary that can be used to construct a language-neutral representation of a query.
  org.modeshape.jcr.query.optimize | This package contains the Optimizer interface, a rule-based optimizer implementation, and library of optimization rules.
  org.modeshape.jcr.query.parse | This package defines the `QueryParser` interface, which defines a component that can parse a query represented in a specific language and produce the corresponding `abstract query model` representation.
  org.modeshape.jcr.query.validate | This package provides the interfaces that define the tables and columns that can be queried.
