Interface TreeSelectionModel<T>

Type Parameters:
T - type of node
All Known Implementing Classes:
DefaultTreeSelectionModel

public interface TreeSelectionModel<T>

Tracks which leaf nodes of a TreeModel are currently selected. The default implementation simply stores a set of unique node ids to identify selected nodes. The selection model is updated whenever the user clicks on the label for a leaf node.

In the future, new methods may be added that will support selection of folders as well as leafs, and define the rules for how selections and de-selections propagate down to children or up to parents.
