ActionEvent.Type, AsyncMedia.MediaErrorType, AsyncMedia.State, AudioRecorderComponent.RecorderState, BarChart.Type, BrowserComponent.JSType, Byte, Charset, ConnectionRequest.CachingMode, Date, DialRenderer.Type, Double, Duration, ElementType, Enum, Float, GradientDrawable.Orientation, Instant, Integer, LocalDate, LocalDateTime, LocalTime, Long, MultipleGradientPaint.ColorSpaceType, MultipleGradientPaint.CycleMethod, OffsetDateTime, Paint.Style, PointStyle, Promise.State, RetentionPolicy, Short, SQLMap.SqlType, String, TextSelection.TextSelectionTrigger, Toolbar.BackCommandPolicy, Validator.HighlightMode, WindowEvent.Type, XYMultipleSeriesRenderer.Orientation, XYSeriesRenderer.FillOutsideLine.Type, ZonedDateTime
public interface Comparable<T>
This interface should be implemented by all classes that wish to define a natural order of their instances. Collections.sort(List) and java.util.Arrays#sort can then be used to automatically sort lists of classes that implement this interface.

The order rule must be both transitive (if x.compareTo(y) < 0 and y.compareTo(z) < 0, then x.compareTo(z) < 0 must hold) and invertible (the sign of the result of x.compareTo(y) must be equal to the negation of the sign of the result of y.compareTo(x) for all combinations of x and y).

In addition, it is recommended (but not required) that if and only if the result of x.compareTo(y) is zero, then the result of x.equals(y) should be true.

  • Method Details

    • compareTo

      int compareTo(T another)
      Compares this object to the specified object to determine their relative order.
      Parameters:
      another - the object to compare to this instance.
      Returns:
      a negative integer if this instance is less than another; a positive integer if this instance is greater than another; 0 if this instance has the same order as another.
      Throws:
      ClassCastException - if another cannot be converted into something comparable to this instance.
