ListDataEvent

public class ListDataEvent extends EventObject
Defines an event that encapsulates changes to a list.

Warning: Serialized objects of this class will not be compatible with future Swing releases. The current serialization support is appropriate for short term storage or RMI between applications running the same version of Swing. As of 1.4, support for long term storage of all JavaBeansTM has been added to the java.beans package. Please see {@link java.beans.XMLEncoder}.

Constructors Summary
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.

param
source the source Object (typically this)
param
type an int specifying {@link #CONTENTS_CHANGED}, {@link #INTERVAL_ADDED}, or {@link #INTERVAL_REMOVED}
param
index0 one end of the new interval
param
index1 the other end of the new interval

        super(source);
	this.type = type;
	this.index0 = Math.min(index0, index1);
	this.index1 = Math.max(index0, index1);
Methods Summary
public intgetIndex0()
Returns the lower index of the range. For a single element, this value is the same as that returned by {@link #getIndex1}.

return
an int representing the lower index value

 return index0;
public intgetIndex1()
Returns the upper index of the range. For a single element, this value is the same as that returned by {@link #getIndex0}.

return
an int representing the upper index value

 return index1;
public intgetType()
Returns the event type. The possible values are:
  • {@link #CONTENTS_CHANGED}
  • {@link #INTERVAL_ADDED}
  • {@link #INTERVAL_REMOVED}

return
an int representing the type value


                                   
        return type;
public java.lang.StringtoString()
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.

return
