    • registerComparator

      public void registerComparator(String fieldLocation, 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(String[] regexes, 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(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 Comparator<?> getComparatorForField(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

      public Stream<Map.Entry<String,Comparator<?>>> comparatorByFields()
      Returns a sequence of associated field-comparator pairs.
      Returns:
      sequence of field-comparator pairs

    • comparatorByRegexFields

      public Stream<Map.Entry<List<Pattern>,Comparator<?>>> comparatorByRegexFields()

    • isEmpty

      public boolean isEmpty()
      Returns:

    • get

      public Comparator<?> get(String fieldLocation)
      Retrieves a specific entity which is associated with the giving filedLocation from the field holder, if it presents. Otherwise, this method returns null.
      Parameters:
