EMPTY

public static final 
TreeSelection EMPTY
The canonical empty selection. This selection should be used instead of null.

TreeSelection

public TreeSelection(
TreePath[] paths)
Constructs a selection based on the elements identified by the given tree paths.

Parameters:
paths - tree paths

TreeSelection

public TreeSelection(
TreePath[] paths,
                     
IElementComparer comparer)
Constructs a selection based on the elements identified by the given tree paths.

Parameters:
paths - tree paths
comparer - the comparer, or null if default equals is to be used

TreeSelection

public TreeSelection(
TreePath treePath)
Constructs a selection based on the elements identified by the given tree path.

Parameters:
treePath - tree path, or null for an empty selection

TreeSelection

public TreeSelection(
TreePath treePath,
                     
IElementComparer comparer)
Constructs a selection based on the elements identified by the given tree path.

Parameters:
treePath - tree path, or null for an empty selection
comparer - the comparer, or null if default equals is to be used
