org.modeshape.jcr.query.QueryContext

Packages that use QueryContext

Package	Description
org.modeshape.jcr.query	The Query API provides a mechanism for building and executing queries.
org.modeshape.jcr.query.lucene	The core query engine, which currently uses Lucene for indexing and raw queries, and the Hibernate Search engine (which does not depend on or use Hibernate Core or JPA) for updating and querying the Lucene indexes.
org.modeshape.jcr.query.lucene.basic	The "basic" Lucene schema has a single index in which all node and property information are indexed into separate fields.
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.plan	This package defines the Planner interface, the CanonicalPlanner implementation, and the PlanNode class that is used to represent a canonical query plan.
org.modeshape.jcr.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.modeshape.jcr.query.validate	This package provides the interfaces that define the tables and columns that can be queried.
