 long elementIndex)

Description copied from interface: ColumnRegionShort

Get a single short from this region.

Specified by:

getShort in interface ColumnRegionShort<ATTR extends Attributes.Values>

Parameters:

context - A ColumnRegionFillContext to enable resource caching where suitable, with current region index pointing to this region

elementIndex - Element (short) index in the table's address space

public Index binSearchMatch(long firstKey,
 long lastKey,
 @NotNull
 SortPair sortPair,
 @NotNull
 Object[] keys)

Description copied from interface: ColumnRegion
