Class RouteModelComparators

java.lang.Object

slash.navigation.converter.gui.comparators.RouteModelComparators

public class RouteModelComparators
extends Object

Creates Comparators that sort the RouteModels of the browse routes table when a column header is clicked. Name and creator sort case-insensitively with missing values (via Comparator.nullsLast(java.util.Comparator<? super T>)) sorting last; length and duration sort numerically on the underlying DistanceAndTime metadata. Missing length/duration values (rendered as –) rank as the largest value. A TableRowSorter negates the comparator for the descending order, so missing rows sort last ascending and first descending; treating an unknown value as the maximum is the intended, consistent semantic here. Pinning missing values last in both directions is not achievable through a plain Comparator (the row sorter negates the result after the comparator returns) without subclassing the row sorter's internals, so it is deliberately not attempted.
