Sole constructor.

Method Detail

getWrapped

public PointValues getWrapped()

intersect

public void intersect(PointValues.IntersectVisitor visitor)
               throws java.io.IOException

Description copied from class: PointValues

Finds all documents and points matching the provided visitor. This method does not enforce live documents, so it's up to the caller to test whether each document is deleted, if necessary.

Specified by:

intersect in class PointValues

Throws:

java.io.IOException

estimatePointCount

public long estimatePointCount(PointValues.IntersectVisitor visitor)

Description copied from class: PointValues

Estimate the number of points that would be visited by PointValues.intersect(org.apache.lucene.index.PointValues.IntersectVisitor) with the given PointValues.IntersectVisitor. This should run many times faster than PointValues.intersect(IntersectVisitor).

Specified by:

estimatePointCount in class PointValues

getMinPackedValue

public byte[] getMinPackedValue()
                         throws java.io.IOException

Description copied from class: PointValues

Returns minimum value for each dimension, packed, or null if PointValues.size(org.apache.lucene.index.IndexReader, java.lang.String) is 0

Specified by:

getMinPackedValue in class PointValues

Throws:

java.io.IOException

getMaxPackedValue

public byte[] getMaxPackedValue()
                         throws java.io.IOException

Specified by:

getMaxPackedValue in class PointValues

Throws:

java.io.IOException

getNumDimensions

public int getNumDimensions()
                     throws java.io.IOException

Description copied from class: PointValues

Returns how many dimensions were indexed

Specified by:
