    • ListDataEvent

      public ListDataEvent(Object source, int type, int index0, int index1)
      Constructs a ListDataEvent object. If index0 is > index1, index0 and index1 will be swapped such that index0 will always be <= index1.
      Parameters:
      source - the source Object (typically this)
      type - an int specifying CONTENTS_CHANGED, INTERVAL_ADDED, or INTERVAL_REMOVED
      index0 - one end of the new interval
      index1 - the other end of the new interval

  • Method Details

    • getType

      public int getType()
      Returns the event type. The possible values are:
      Returns:
      an int representing the type value

    • getIndex0

      public int getIndex0()
      Returns the lower index of the range. For a single element, this value is the same as that returned by getIndex1().
      Returns:
      an int representing the lower index value

    • getIndex1

      public int getIndex1()
      Returns the upper index of the range. For a single element, this value is the same as that returned by getIndex0().
      Returns:
      an int representing the upper index value

    • toString

      public String toString()
      Returns a string representation of this ListDataEvent. This method is intended to be used only for debugging purposes, and the content and format of the returned string may vary between implementations. The returned string may be empty but may not be null.
      Overrides:
      toString in class EventObject
      Returns:
      a string representation of this ListDataEvent.
