org.modeshape.jcr.query |
The Query API provides a mechanism for building and executing queries.
|
org.modeshape.jcr.query.engine |
This package contains several fully-functional query engine implementations.
|
org.modeshape.jcr.query.optimize |
This package contains the Optimizer interface, a rule-based optimizer implementation, and library of optimization rules.
|
org.modeshape.jcr.spi.query |
This package contains the Service Provider Interface (SPI) for custom index providers, which are components that encapsulate
how ModeShape updates and uses a set of particular indexes.
|
Class and Description |
---|
QueryIndexProvider |
QueryIndexWriter
Interface used to record in the indexes the changes to content.
|
QueryIndexWriter.IndexingContext
The context of a set of indexing operations, typically aligned with and part of a single transaction.
|
Class and Description |
---|
IndexCollector
A collector implemented by ModeShape and supplied to the
QueryIndexPlanner.applyIndexes(QueryContext, SelectorName, List, IndexCollector) method so that the
QueryIndexPlanner can add indexes to the query plan. |
QueryIndex
A provider-specific index used by the query system to quickly provide the set of
NodeKey s that satisfy a particular
portion of a query. |
QueryIndex.Operation
A potentially executable stateful operation that returns the set of nodes that satisfies the constraints supplied when the
operation is
created . |
QueryIndex.ResultWriter
A writer passed by ModeShape to a
QueryIndex.Operation instance when the query engine needs additional results for the query. |
QueryIndexPlanner
A provider-specific component obtained by ModeShape and then used in the planning and optimization phases of each query to
identify which provider-specific indexes, if any, can be used in the processing phase to most-efficiently obtain the set of
nodes that satisfies the given criteria.
