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.

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
