  • All Implemented Interfaces:

    public final class LatestValueFunction
    extends java.lang.Object
    implements Quantize.Function.Factory
    Simple quantize function which just returns the last value add to the distribution bucket.

    Its purpose is performance optimization: Assume you want to create a frequency distribution on column value A and you know there is a 1:1 relationship to column value B, one can use the LatestValueFunction to display column value B instead of adding B to the composite key (A,B).
