Class XmlMatchingRule

  • All Implemented Interfaces:
    MatchingRule<String>
    public class XmlMatchingRule
extends Object
implements MatchingRule<String>
    String matching rule that compares strings as XML snippets. The XML comparison is not schema aware. It will not handle QNames in values correctly. The comparison ignores XML formatting (whitespaces between elements).

      • getName

        public QName getName()
        Description copied from interface: MatchingRule
        QName that identifies the rule. This QName may be used to refer to this specific matching rule, it is an matching rule identifier.
        Specified by:
        getName in interface MatchingRule<String>

      • supports

        public boolean supports​(QName xsdType)
        Description copied from interface: MatchingRule
        Returns true if the rule can be applied to the specified XSD type.
        Specified by:
        supports in interface MatchingRule<String>

      • normalize

        public String normalize​(String original)
        Description copied from interface: MatchingRule
        Returns a normalized version of the value. For normalized version the following holds: if A matches B then normalize(A) == normalize(B) FIXME Currently, the implementation of PolyStringNormMatchingRule does not fulfill this contract. The main problem is that this method returns a value of the same type as it was called with. It may not be appropriate for holding the normalized value. In the case of PolyString norm, we should rather return String instead of PolyString. A similar case could be with comparing e.g. IP addresses where an array or a list of numbers would be appropriate as the normalized representation. (Note: In midPoint provisioning module, we rely on the method returning an object with the same type. But currently, all values used there should be of String type. When introducing other types of attributes, this question will need to be resolved.)
