ListSelectionModel (Java Platform SE 7 )

All Known Implementing Classes:

DefaultListSelectionModel
```
public interface ListSelectionModel
```
This interface represents the current state of the selection for any of the components that display a list of values with stable indices. The selection is modeled as a set of intervals, each interval represents a contiguous range of selected list elements. The methods for modifying the set of selected intervals all take a pair of indices, index0 and index1, that represent a closed interval, i.e. the interval includes both index0 and index1.

`static int`	`SINGLE_INTERVAL_SELECTION` A value for the selectionMode property: select one contiguous range of indices at a time.
`static int`	`SINGLE_SELECTION` A value for the selectionMode property: select one list index at a time.

Method Summary

Methods
Modifier and Type	Method and Description
`void`	`addListSelectionListener(ListSelectionListener x)` Add a listener to the list that's notified each time a change to the selection occurs.
`void`	`addSelectionInterval(int index0, int index1)` Changes the selection to be the set union of the current selection and the indices between `index0` and `index1` inclusive.
`void`	`clearSelection()` Change the selection to the empty set.
`int`	`getAnchorSelectionIndex()` Return the first index argument from the most recent call to setSelectionInterval(), addSelectionInterval() or removeSelectionInterval().
`int`	`getLeadSelectionIndex()` Return the second index argument from the most recent call to setSelectionInterval(), addSelectionInterval() or removeSelectionInterval().
`int`	`getMaxSelectionIndex()` Returns the last selected index or -1 if the selection is empty.
`int`	`getMinSelectionIndex()` Returns the first selected index or -1 if the selection is empty.
`int`	`getSelectionMode()` Returns the current selection mode.
`boolean`	`getValueIsAdjusting()` Returns `true` if the selection is undergoing a series of changes.
`void`	`insertIndexInterval(int index, int length, boolean before)` Insert length indices beginning before/after index.
`boolean`	`isSelectedIndex(int index)` Returns true if the specified index is selected.
`boolean`	`isSelectionEmpty()` Returns true if no indices are selected.
`void`	`removeIndexInterval(int index0, int index1)` Remove the indices in the interval index0,index1 (inclusive) from the selection model.
`void`	`removeListSelectionListener(ListSelectionListener x)` Remove a listener from the list that's notified each time a change to the selection occurs.
`void`	`removeSelectionInterval(int index0, int index1)` Changes the selection to be the set difference of the current selection and the indices between `index0` and `index1` inclusive.
`void`	`setAnchorSelectionIndex(int index)` Set the anchor selection index.
`void`	`setLeadSelectionIndex(int index)` Set the lead selection index.
`void`	`setSelectionInterval(int index0, int index1)` Changes the selection to be between `index0` and `index1` inclusive.
`void`	`setSelectionMode(int selectionMode)` Sets the selection mode.
`void`	`setValueIsAdjusting(boolean valueIsAdjusting)` Sets the `valueIsAdjusting` property, which indicates whether or not upcoming selection changes should be considered part of a single change.

  - SINGLE_SELECTION
```
static final int SINGLE_SELECTION
```
    A value for the selectionMode property: select one list index at a time.

    setSelectionMode(int), Constant Field Values
  - SINGLE_INTERVAL_SELECTION
```
static final int SINGLE_INTERVAL_SELECTION
```
    A value for the selectionMode property: select one contiguous range of indices at a time.

  - MULTIPLE_INTERVAL_SELECTION
```
static final int MULTIPLE_INTERVAL_SELECTION
```
    A value for the selectionMode property: select one or more contiguous ranges of indices at a time.

  - setSelectionInterval
```
void setSelectionInterval(int index0,
                        int index1)
```
    Changes the selection to be between index0 and index1 inclusive. index0 doesn't have to be less than or equal to index1.
    In SINGLE_SELECTION selection mode, only the second index is used.
    If this represents a change to the current selection, then each ListSelectionListener is notified of the change.
    
    Parameters:
    index0 - one end of the interval.
    index1 - other end of the interval

    addListSelectionListener(javax.swing.event.ListSelectionListener)
  - addSelectionInterval
```
void addSelectionInterval(int index0,
                        int index1)
```
    Changes the selection to be the set union of the current selection and the indices between index0 and index1 inclusive. index0 doesn't have to be less than or equal to index1.
    In SINGLE_SELECTION selection mode, this is equivalent to calling setSelectionInterval, and only the second index is used. In SINGLE_INTERVAL_SELECTION selection mode, this method behaves like setSelectionInterval, unless the given interval is immediately adjacent to or overlaps the existing selection, and can therefore be used to grow the selection.
    If this represents a change to the current selection, then each ListSelectionListener is notified of the change.
    
    Parameters:
    index0 - one end of the interval.
    index1 - other end of the interval
    See Also:
    addListSelectionListener(javax.swing.event.ListSelectionListener), setSelectionInterval(int, int)
  - removeSelectionInterval
```
void removeSelectionInterval(int index0,
                           int index1)
```
    Changes the selection to be the set difference of the current selection and the indices between index0 and index1 inclusive. index0 doesn't have to be less than or equal to index1.
    In SINGLE_INTERVAL_SELECTION selection mode, if the removal would produce two disjoint selections, the removal is extended through the greater end of the selection. For example, if the selection is 0-10 and you supply indices 5,6 (in any order) the resulting selection is 0-4.
    If this represents a change to the current selection, then each ListSelectionListener is notified of the change.
    
    Parameters:
    index0 - one end of the interval.
    index1 - other end of the interval

    addListSelectionListener(javax.swing.event.ListSelectionListener)
  - getMinSelectionIndex
```
int getMinSelectionIndex()
```
    Returns the first selected index or -1 if the selection is empty.
  - getMaxSelectionIndex
```
int getMaxSelectionIndex()
```
    Returns the last selected index or -1 if the selection is empty.
  - isSelectedIndex
```
boolean isSelectedIndex(int index)
```
    Returns true if the specified index is selected.
  - getAnchorSelectionIndex
```
int getAnchorSelectionIndex()
```
    Return the first index argument from the most recent call to setSelectionInterval(), addSelectionInterval() or removeSelectionInterval(). The most recent index0 is considered the "anchor" and the most recent index1 is considered the "lead". Some interfaces display these indices specially, e.g. Windows95 displays the lead index with a dotted yellow outline.
