                                            )

Count of nodes in tree. It overrides Nodes.getNodeCount because the root node should not be counted.

Returns: int: number of nodes in the tree

getNodeDefinition

                                            getNodeDefinition
                                           (
                                            )

Returns an object which could be used to build a tree out of this node and its children. It can be passed to the tree constructor to reproduce this node as a tree. Since the RootNode is automatically created by treeView, its own definition is excluded from the returned node definition which only contains its children.

Returns: Object | false: definition of the tree or false if any child node is defined as dynamic
