Package com.apple.foundationdb.record.lucene

Class LucenePlanner

java.lang.Object

com.apple.foundationdb.record.query.plan.RecordQueryPlanner

com.apple.foundationdb.record.lucene.LucenePlanner

All Implemented Interfaces:

QueryPlanner

public class LucenePlanner
extends RecordQueryPlanner

A planner to implement lucene query planning so that we can isolate the lucene functionality to a distinct package. This was necessary because of the need to pass the sort key expression into the plan created and from there into the record cursor which creates a Lucene sort object.
