      • registerComparator

        public void registerComparator​(java.lang.String fieldLocation,
                               java.util.Comparator<?> comparator)
        Registers the comparator for the given fieldLocation.
        Parameters:
        fieldLocation - the location where to apply the comparator
        comparator - the comparator itself

      • registerComparatorForFieldsMatchingRegexes

        public void registerComparatorForFieldsMatchingRegexes​(java.lang.String[] regexes,
                                                       java.util.Comparator<?> comparator)
        Registers the comparator for the given regexes field location.
        Parameters:
        regexes - the regexes field location where to apply the comparator
        comparator - the comparator to use for the regexes

      • hasComparatorForField

        public boolean hasComparatorForField​(java.lang.String fieldLocation)
        Checks, whether an any comparator is associated with the giving field location.
        Parameters:
        fieldLocation - the field location which association need to check
        Returns:
        is field location contain a custom comparator

      • getComparatorForField

        public java.util.Comparator<?> getComparatorForField​(java.lang.String fieldLocation)
        Retrieves a custom comparator, which is associated with the giving field location. If this location does not associate with any custom comparators - this method returns null.
        Parameters:
        fieldLocation - the field location that has to be associated with a comparator
        Returns:
        a custom comparator or null

      • comparatorByFields

        Returns a sequence of associated field-comparator pairs.
        Returns:
        sequence of field-comparator pairs
