public interface BaseLongColumnValueSelector
extends HotLoopCallee, BaseNullableColumnValueSelector

Long value selecting polymorphic "part" of the ColumnValueSelector interface. Users of getLong() are encouraged to reduce the parameter/field/etc. type to BaseLongColumnValueSelector to make it impossible to accidently call any method other than getLong(). All implementations of this interface MUST also implement ColumnValueSelector.
