true if there is another centroid to process

value

public double value()

Description copied from interface: TDigestToExponentialHistogramConverter.CentroidIterator

Must only be called if TDigestToExponentialHistogramConverter.CentroidIterator.hasNext() returned true.

Specified by:

value in interface TDigestToExponentialHistogramConverter.CentroidIterator

Returns:

the current centroid's value

count

public long count()

Description copied from interface: TDigestToExponentialHistogramConverter.CentroidIterator

Must only be called if TDigestToExponentialHistogramConverter.CentroidIterator.hasNext() returned true.

Specified by:

count in interface TDigestToExponentialHistogramConverter.CentroidIterator

Returns:

the current centroid's count

advance

public void advance()

Description copied from interface: TDigestToExponentialHistogramConverter.CentroidIterator

Advance to the next centroid.

Specified by:

advance in interface TDigestToExponentialHistogramConverter.CentroidIterator

reversedCopy

public TDigestToExponentialHistogramConverter.CentroidIterator reversedCopy()

Description copied from interface: TDigestToExponentialHistogramConverter.CentroidIterator

Creates a copy of this iterator that iterates over the centroids this iterator already skipped via TDigestToExponentialHistogramConverter.CentroidIterator.advance(), but in reverse order.

Specified by:

reversedCopy in interface TDigestToExponentialHistogramConverter.CentroidIterator
