ListDataEvent back to summary

ListDataEvent	back to 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. Parameters source:Object the source Object (typically `this`) type:int an int specifying `CONTENTS_CHANGED`, `INTERVAL_ADDED`, or `INTERVAL_REMOVED` index0:int one end of the new interval index1:int the other end of the new interval

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:Object: the source Object (typically this)
type:int: an int specifying CONTENTS_CHANGED, INTERVAL_ADDED, or INTERVAL_REMOVED
index0:int: one end of the new interval
index1:int: the other end of the new interval

Method Detail

getIndex0 back to summary

getIndex0	back to summary
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:int an int representing the lower index value

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:int: an int representing the lower index value

getIndex1 back to summary

getIndex1	back to summary
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:int an int representing the upper 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:int: an int representing the upper index value

getType back to summary

getType	back to summary
public int getType() Returns the event type. The possible values are: `CONTENTS_CHANGED` `INTERVAL_ADDED` `INTERVAL_REMOVED` Returns:int an int representing the type value

public int getType()

Returns the event type. The possible values are:

Returns:int: an int representing the type value

toString back to summary

toString	back to summary
public String toString() Overrides java.util.EventObject.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:String a string representation of this ListDataEvent. Since 1.4

public String toString()

Overrides java.util.EventObject.toString.
