Description

GGandivaSelectionVector is a base class for a selection vector.

GGandivaUInt16SelectionVector is a class for a selection vector that uses 16-bit unsigned integer for each index.

GGandivaUInt32SelectionVector is a class for a selection vector that uses 32-bit unsigned integer for each index.

GGandivaUInt64SelectionVector is a class for a selection vector that uses 64-bit unsigned integer for each index.

Functions
