org.jboss.dna.graph.query.QueryContext

Packages that use QueryContext

org.jboss.dna.graph.query	The Query API provides a mechanism for building and executing queries.
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.plan	This package defines the Planner interface, the CanonicalPlanner implementation, and the PlanNode class that is used to represent a canonical query plan.
org.jboss.dna.graph.query.process	This package defines the QueryProcessor interface, which is responsible for constructing for each query a tree of ProcessingComponent objects that each are responsible for processing a specific aspect of the query and returning the tuples to the parent component.
org.jboss.dna.graph.query.validate	This package provides the interfaces that define the tables and columns that can be queried.
