Interface FloatColumnSelector

All Superinterfaces:

ColumnValueSelector<Float>, HotLoopCallee

All Known Implementing Classes:

ZeroFloatColumnSelector

public interface FloatColumnSelector
extends ColumnValueSelector<Float>, HotLoopCallee

An object that gets a metric value. Metric values are always floats and there is an assumption that the FloatColumnSelector has a handle onto some other stateful object (e.g. an Offset) which is changing between calls to get() (though, that doesn't have to be the case if you always want the same value...).
