Method Summary

SegmentDataset	createSegmentDataset(Segment segment) Returns a SegmentDataset object which contains the cached data and is initialized to be used with the supplied segment.
SortedSet<Comparable<?>>[]	getAxisValueSets() Returns the cached axis value sets to be used as an initializer for the segment's axis.
boolean[]	getNullAxisFlags() Returns an array of boolean values which identify which axis of the cached segment contained null values.

Method Detail

createSegmentDataset

SegmentDataset createSegmentDataset(Segment segment)

Returns a SegmentDataset object which contains the cached data and is initialized to be used with the supplied segment.

Parameters:

segment - Segment to which the returned dataset will be associated to.

Returns:

A SegmentDataset object which contains cached data.

getAxisValueSets

SortedSet<Comparable<?>>[] getAxisValueSets()

Returns the cached axis value sets to be used as an initializer for the segment's axis.

Returns:

An array of SortedSets which was cached previously.

getNullAxisFlags

boolean[] getNullAxisFlags()

Returns an array of boolean values which identify which axis of the cached segment contained null values.

Returns:

An array of boolean values.
