Class ScopedIFComparator<T extends ScopedIF>
java.lang.Object
net.ontopia.topicmaps.utils.ScopedIFComparator<T>
- All Implemented Interfaces:
- Comparator<T>
- Direct Known Subclasses:
- BaseNameComparator, TopicNameComparator
public class ScopedIFComparator<T extends ScopedIF>
- extends Object
- implements Comparator<T>
INTERNAL: Comparator that compares ScopedIF objects based on their
applicability in the specified scope.
This comparator may only be used with objects that are
implementations of ScopedIF. The default subcomparator is
LexicalComparator.CASE_SENSITIVE.
Technique:
- Compare the number of matching themes for each of the objects. The
more matching themes, the higher ranked.
- Compare by number of themes specified on objects. The fewer
themes, the higher ranked.
- If subcomparator doesn't exist they're ranked equally.
- Use subcomparator to compare them.
