Class RegionedPushdownAction

java.lang.Object

io.deephaven.engine.table.impl.sources.regioned.RegionedPushdownAction

Direct Known Subclasses:

RegionedPushdownAction.Location, RegionedPushdownAction.Region

public abstract class RegionedPushdownAction
extends Object

This class is used to represent a pushdown action that can be performed on a regioned column source. Note that the logic to perform this action is not contained in this class.
