Class BucketState

java.lang.Object

com.illumon.iris.clientsupport.plotdownsampling.BucketState

public class BucketState
extends Object

Represents a given "pixel" in the downsampled output - the first and last value within that pixel, and the max/min value of each column we're interested in within that pixel. The arrays of values for a given downsampled table are shared between all states, so each BucketState instance tracks its own offset in those arrays.
