All Implemented Interfaces:

Comparator<TaxonNode>

Direct Known Subclasses:

TaxonNodeByNameComparator

@Component
public abstract class AbstractStringComparator
extends Object
implements Comparator<TaxonNode>

Abstract Comparator for Strings which allows define substitution rules which are applied to the String to be compared before the actual comparison takes place. By this it is e.g. possible to influence the position of objects in sorted lists etc.

Intended usage: To allow maximum flexibility the property setSubstitutionRules(Map) should be set in the spring application context.
