  - getAccessibleSelectionCount
```
public int getAccessibleSelectionCount()
```
    Returns the number of items currently selected. If no items are selected, the return value will be 0.
    
    Specified by:
    
    getAccessibleSelectionCount in interface AccessibleSelection
    
    Returns:
    the number of items currently selected.
  - getAccessibleSelection
```
public Accessible getAccessibleSelection(int i)

    Specified by:
    
    getAccessibleSelection in interface AccessibleSelection
    
    Parameters:
    i - the zero-based index of selected items

  - isAccessibleChildSelected
```
public boolean isAccessibleChildSelected(int i)
```
    Returns true if the current child of this object is selected.
    
    Specified by:

  - addAccessibleSelection
```
public void addAccessibleSelection(int i)
```
    Adds the specified selected item in the object to the object's selection.

    AccessibleContext.getAccessibleChild(int)
  - removeAccessibleSelection
```
public void removeAccessibleSelection(int i)
```
    Removes the specified selected item in the object from the object's selection. If the specified item isn't currently selected, this method has no effect.
    
    Specified by:
    
    removeAccessibleSelection in interface AccessibleSelection
    
    Parameters:
    i - the zero-based index of selectable items
    See Also:
    AccessibleContext.getAccessibleChild(int)
  - clearAccessibleSelection
```
public void clearAccessibleSelection()
```
    Clears the selection in the object, so that nothing in the object is selected.
    
    Specified by:
    
    clearAccessibleSelection in interface AccessibleSelection
  - selectAllAccessibleSelection
```
public void selectAllAccessibleSelection()
```
    Causes every selected item in the object to be selected if the object supports multiple selections.
    
    Specified by:
    
    selectAllAccessibleSelection in interface AccessibleSelection
  - getAccessibleActionCount
```
public int getAccessibleActionCount()
```
    Returns the number of accessible actions available in this tree node. If this node is not a leaf, there is at least one action (toggle expand), in addition to any available on the object behind the TreeCellRenderer.
    
    Specified by:
    
    getAccessibleActionCount in interface AccessibleAction
    
    Returns:
    the number of Actions in this object
  - getAccessibleActionDescription
```
public String getAccessibleActionDescription(int i)
```
    Return a description of the specified action of the tree node. If this node is not a leaf, there is at least one action description (toggle expand), in addition to any available on the object behind the TreeCellRenderer.
    
    Specified by:
    
    getAccessibleActionDescription in interface AccessibleAction
    
    Parameters:
    i - zero-based index of the actions
    
    Returns:
    a description of the action
    See Also:
    AccessibleAction.getAccessibleActionCount()
  - doAccessibleAction
```
public boolean doAccessibleAction(int i)
```

    Specified by:
    
    doAccessibleAction in interface AccessibleAction
    
    Parameters:
    i - zero-based index of actions
