Interface FloatColumnSelector

All Superinterfaces:

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

All Known Implementing Classes:

SettableFloatColumnValueSelector

public interface FloatColumnSelector
extends ColumnValueSelector<Float>

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