Packages that use org.jboss.dna.graph.query.model

org.jboss.dna.graph	The JBoss DNA Graph API defines the types that allow you to work with content organized as a graph.

org.jboss.dna.graph.property.basic	A set of basic implementations of the various interfaces defined in org.jboss.dna.graph.property.
org.jboss.dna.graph.query	The Query API provides a mechanism for building and executing queries.
org.jboss.dna.graph.query.model	The Abstract Query Model is a vocabulary that can be used to construct a language-neutral representation of a query.
org.jboss.dna.graph.query.optimize	This package contains the Optimizer interface, a rule-based optimizer implementation, and library of optimization rules.
org.jboss.dna.graph.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.
