Method Detail

getAxisValueSets

public SortedSet<Comparable>[] getAxisValueSets()

Description copied from interface: SegmentBody

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

Specified by:

getAxisValueSets in interface SegmentBody

Returns:

An array of SortedSets which was cached previously.

getNullAxisFlags

public boolean[] getNullAxisFlags()

Description copied from interface: SegmentBody

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

Specified by:

getNullAxisFlags in interface SegmentBody

Returns:

An array of boolean values.

getValueMap

public Map<CellKey,Object> getValueMap()

Description copied from interface: SegmentBody

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

Specified by:

getValueMap in interface SegmentBody

Returns:

Map containing cell values keyed by their coordinates

getValueArray

public Object getValueArray()

Description copied from interface: SegmentBody

Returns an array of values.

Use only for dense segments.

Specified by:

getValueArray in interface SegmentBody

Returns:

An array of values

getNullValueIndicators

public BitSet getNullValueIndicators()

Description copied from interface: SegmentBody

Returns a bit-set indicating whether values are null. The ordinals in the bit-set correspond to the indexes in the array returned from SegmentBody.getValueArray().

Use only for dense segments of native values.

Specified by:

getNullValueIndicators in interface SegmentBody

Returns:

Indicators

getSize

protected abstract int getSize()

getObject

protected abstract Object getObject(int i)
