Class TimeBinIndex

java.lang.Object
com.google.refine.browsing.util.TimeBinIndex
Direct Known Subclasses:
TimeBinRecordIndex, TimeBinRowIndex
public abstract class TimeBinIndex extends Object
A utility class for computing the base bins that form the base histograms of temporal range facets. It evaluates an expression on all the rows of a project to get temporal values, determines how many bins to distribute those values in, and bins the rows accordingly. This class processes all rows rather than just the filtered rows because it needs to compute the base bins of a temporal range facet, which remain unchanged as the user interacts with the facet.
