Constructor Detail
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 (typicallythis) -
type- an int specifyingCONTENTS_CHANGED,INTERVAL_ADDED, orINTERVAL_REMOVED -
index0- one end of the new interval -
index1- the other end of the new interval

Method Detail
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 bygetIndex1().- 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 bygetIndex0().- 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 benull.- Overrides:
-
toStringin classEventObject - Returns:
- a string representation of this ListDataEvent.
