org.modeshape.jcr.spi.index.Index

An index used by the query system to quickly provide the set of {@link NodeKey}s that satisfy a particular portion of a query.

Each time ModeShape uses this index, it calls the {@link #filter(IndexConstraints)} method with a set of{@link IndexConstraints} to obtain an {@link org.modeshape.jcr.spi.index.provider.Filter.Results} instance that ModeShape willthen use to {@link org.modeshape.jcr.spi.index.provider.Filter.Results#getNextBatch(ResultWriter,int) access} the batches ofnode keys that satisfy the constraints. Note that once an {@link org.modeshape.jcr.spi.index.provider.Filter.Results} isobtained, it may be called zero or more times but will always be closed.
