org.freeplane.features.map.NodeModel
This class represents a single Node of a Tree. It contains direct handles to its parent and children and to its view. Note that this class does not and must not know anything about its extensions, otherwise this class would become too big. Extension methods that add functionality to nodes are in the extension packages and get NodeModel as an argument.
