    - a value greater than zero, if "a" is greater than "b" such that "b" should appear earlier in the list

  - ### sort

    public RecordList sort(Comparator<Record> comparator)
    Sorts the elements of the List in place.

    The optional comparator function should take two parameters "a" and "b" which are the two list items to compare, and should return:

    - a value less than zero, if "a" is less than "b" such that "a" should appear earlier in the list

    Sort a list of objects by a given property of each item.

    The optional normalizer, if passed as a function, is called for each item in the List, and should return whatever value should be used for sorting, which does not have to agree with the property value. By passing a normalizer function you can achieve any kind of sorting you'd like, including sorting by multiple properties.

    NOTE: string sort is case INsensitive by default

    Parameters:
      `property` - name of the property to sort by
      `up` - true == sort ascending, false == sort descending
    Returns:
      the list itself

  - ### sortByProperty

    public void sortByProperty(String property, boolean up, RecordList.SortNormalizer normalizer)
    Sort this ResultSet by a property of each record.

    Sorting is performed on the client for a ResultSet that has a full cache for the current filter criteria. Otherwise, sorting is performed by the server, and changing the sort order will invalidate the cache.

    NOTE: normalizers are not supported by ResultSets in "paged" mode

    Parameters:
      `property` - name of the property to sort by
      `up` - true == sort ascending, false == sort descending
      `normalizer` - May be specified as a callbac with signature `normalize(item, propertyName)`, where `item` is reference to the item in the array, `propertyName` is the property by which the array is being sorted. Normalizer function should return the value normalized for sorting.

  - ### setSort

    public void setSort(SortSpecifier... sortSpecifiers)
    Multi-Property sort. Sort this ResultSet by a list of `SortSpecifier`'s.
    Parameters:
      `sortSpecifiers` - a list of `SortSpecifier` objects, one per sort-field and direction

  - ### getValueMap

    public Map getValueMap(String idField, String displayField)
    Get a map of the form `{ item[idField] -> item[displayField] }`, for all items in the list. Note that if more than one item has the same `idProperty`, the value for the later item in the list will clobber the value for the earlier item.
    Parameters:
      `idField` - Property to use as ID (data value) in the valueMap
      `displayField` - Property to use a display value in the valueMap
    Returns:
      valueMap object

  - ### addDataChangedHandler

    public HandlerRegistration addDataChangedHandler(DataChangedHandler handler)
    Add a DataChanged handler.

    Notification fired when data changes in some way. Note that this will only fire when items are added, removed or rearranged. If a list contains objects, this method will not fire if changes are made to objects within the list without changing their position within the list

    Specified by:
      `addDataChangedHandler` in interface `HasDataChangedHandlers`
    Parameters:
      `handler` - the DataChanged handler
    Returns:
      `HandlerRegistration` used to remove this handler

  - ### toArray

      `end` - end position
    Returns:
      a RecordList with the items from start -> end-1
