/**
* A selection containing tree paths.
*
* It is recommended that clients do not implement this interface but instead
* use the standard implementation of this interface, {@link TreeSelection}.
* TreeSelection adds API for getting the {@link IElementComparer}
* of a selection (if available). This is important for clients who want to
* create a slightly modified tree selection based on an existing tree
* selection. The recommended coding pattern in this case is as follows:
*
*
*
* ITreeSelection selection = (ITreeSelection)treeViewer.getSelection();
* TreePath[] paths = selection.getPaths();
* IElementComparer comparer = null;
* if (selection instanceof TreeSelection) {
* comparer = ((TreeSelection)selection).getElementComparer();
* }
* TreePath[] modifiedPaths = ... // modify as required
* TreeSelection modifiedSelection = new TreeSelection(modifiedPaths, comparer);
*
*
* See bugs 135818 and 133375 for details.
*
* @since 3.2
