Class QueryResultSet.ScoreComparator

java.lang.Object
  com.jalios.jcms.QueryResultSet.ScoreComparator

All Implemented Interfaces:

Comparator

Enclosing class:

QueryResultSet

public static class QueryResultSet.ScoreComparator
extends Object
implements Comparator

This Comparator compares two Objects using a score retrieved from a map of Object to float.
If two Storable have the same score, a "parent" compararator is used, default "parent" comparator is MdateComparator.
Note: because a high score must be first, it behaves in the opposite way of what Comparator says see the compare(Object, Object) method.

Returns:

1 when o1 has a lower score than o2, -1 when has o1 higher score than o2 and returns parentComparator.compare value when scores are equals.
