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

Description copied from class: PointValues

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

Specified by:

getMaxPackedValue in class PointValues

Throws:

java.io.IOException

getNumDataDimensions

public int getNumDataDimensions()
                         throws java.io.IOException

Description copied from class: PointValues

Returns how many data dimensions are represented in the values

Specified by:

getNumDataDimensions in class PointValues

Throws:

java.io.IOException

getNumIndexDimensions

public int getNumIndexDimensions()
                          throws java.io.IOException

Description copied from class: PointValues

Returns how many dimensions are used for the index

Specified by:

getNumIndexDimensions in class PointValues

Throws:

java.io.IOException

getBytesPerDimension

public int getBytesPerDimension()
                         throws java.io.IOException

Description copied from class: PointValues

Returns the number of bytes per dimension

Specified by:

getBytesPerDimension in class PointValues

Throws:

java.io.IOException

size

public long size()

Description copied from class: PointValues

Returns the total number of indexed points across all documents.

Specified by:

size in class PointValues

getDocCount

public int getDocCount()

Description copied from class: PointValues

Returns the total number of documents that have indexed at least one point.

Specified by:
