  org.pentaho.reporting.engine.classic.core.metadata.GroupedMetaDataComparator

All Implemented Interfaces:

Comparator

public class GroupedMetaDataComparator
extends Object
implements Comparator

This Comparator implements the standard java.util.Comparator interface. The intended use is to group MetaData elements based on either: (1) The ordinal value in the groupsorting.properties file (see documentation in that file for how this is accomplished. Any group(s) not represented in that file will be displayed last if more than one group they will all be displayed last in alpha order. (2) If the groupsorting.properties doesn't exist or can't be loaded, the value of the *.grouping key (using the standard string compare).

This effectively sorts the attribute and style elements into groups for display by a GUI. Fine grain ordering of the groups can be accomplished using the groupsorting.properties file.
