Class TimeRangeStatistics

java.lang.Object

org.openrefine.browsing.util.TimeRangeStatistics

All Implemented Interfaces:

Serializable

public class TimeRangeStatistics
extends Object
implements Serializable

Stores statistics related to time values stored in a set of rows (generated by an expression). The time values are represented as milliseconds since Epoch, and stored individually in an array. This is different from the numeric facet which does the binning on the fly, because the various possible scales for the timeline facet do not align (for instance, years are not integer multiples of days).
