All Superinterfaces:

Serializable

All Known Implementing Classes:

AbstractSegmentBody, DenseDoubleSegmentBody, DenseIntSegmentBody, DenseObjectSegmentBody, SparseSegmentBody

public interface SegmentBody
extends Serializable

SegmentBody is the object which contains the cached data of a Segment. They are stored inside a SegmentCache and can be retrieved by a SegmentHeader key.

The segment body objects are immutable and fully serializable.

Method Summary

SortedSet<Comparable>[]	getAxisValueSets() Returns the cached axis value sets to be used as an initializer for the segment's axis.
BitSet	getIndicators() Returns a bitset indicating whether values are null.
boolean[]	getNullAxisFlags() Returns an array of boolean values which identify which axis of the cached segment contained null values.
Object	getValueArray() Returns an array of values.
Map<CellKey,Object>	getValueMap() Converts contents of this segment into a cellkey/value map.

Method Detail

getValueMap

Map<CellKey,Object> getValueMap()

Converts contents of this segment into a cellkey/value map. Use only for sparse segments.

Returns:

Map containing cell values keyed by their coordinates

getValueArray

Object getValueArray()

Returns an array of values. Use only for dense segments.

Returns:

An array of values

getIndicators

BitSet getIndicators()

Returns a bitset indicating whether values are null. Use only for dense segments.

Returns:

Indicators

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.
