public static final int INTERVAL_REMOVED
Identifies the removal of one or more contiguous items from the list
Public Constructors
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 |
Public Methods
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
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
public int getType ()
Returns the event type. The possible values are:
Returns
- an int representing the type value
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.
Returns
- a string representation of this ListDataEvent.
