Interface ObjectColumnSelector<T>

All Superinterfaces:

BaseDoubleColumnValueSelector, BaseFloatColumnValueSelector, BaseLongColumnValueSelector, BaseObjectColumnValueSelector<T>, ColumnValueSelector<T>, HotLoopCallee

All Known Implementing Classes:

HyperLogLogCollectorAggregateCombiner, ObjectAggregateCombiner

public interface ObjectColumnSelector<T>
extends ColumnValueSelector<T>

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

default float	getFloat() Deprecated. This method is marked as deprecated in ObjectColumnSelector to minimize the probability of accidential calling. "Polymorphism" of ObjectColumnSelector should be used only when operating on ColumnValueSelector objects.
default long	getLong() Deprecated. This method is marked as deprecated in ObjectColumnSelector to minimize the probability of accidential calling. "Polymorphism" of ObjectColumnSelector should be used only when operating on ColumnValueSelector objects.
