Interface LongColumnSelector

All Superinterfaces:

BaseDoubleColumnValueSelector, BaseFloatColumnValueSelector, BaseLongColumnValueSelector, BaseNullableColumnValueSelector, BaseObjectColumnValueSelector<Long>, ColumnValueSelector<Long>, HotLoopCallee

All Known Implementing Classes:

IncrementalIndexRowHolder, LongAggregateCombiner, LongSumAggregateCombiner, SettableLongColumnValueSelector

public interface LongColumnSelector
extends ColumnValueSelector<Long>

This interface is convenient for implementation of "long-sourcing" ColumnValueSelectors, it provides default implementations for all ColumnValueSelector's methods except BaseLongColumnValueSelector.getLong(). This interface should appear ONLY in "implements" clause or anonymous class creation, but NOT in "user" code, where BaseLongColumnValueSelector must be used instead.
