public class NodeTreeManager extends Object implements NodeListener
JTreewith a view of a node graph. Since
Nodealready implements the
TreeNodeinterface, what we do here is to install a
NodeListeneron a provided
NodeWatcherand keep a
TreeModelup-to-date. In many cases you will not need to set up a
JTreeyourself, but simply create an instance of
Because of the asynchronous nature of node manipulation,
we have decided to not use the
which cannot account for method failures, for example. The proposed
implementation therefore is, to call the node's methods like
run directly, and the tree will be
updated as soon as the
