IlsTreeDataSource
Description
The Tree data source is a bridge class which is notified by the server of creation, deletion, or update events occurring on the tree and its nodes. Thus, a Tree data source is also a source-events class that manages listeners. The class IlsTreeDS2JTreeAdapter provides a default implementation for all events produced by the Tree data source.
Listeners
*DataSourceListener: notified when a creation or update event occurs on the origin of the view, that is, the tree.
*BatchListener: notified when the beginning or the end of a set of events is detected. Listening for these events is not mandatory, but it is useful to optimize operations following changes in the data source.
*TreeDSListener: notified when an item is added, removed, or updated.
Adapter
An adapter (IlsTreeDS2JTreeAdapter) is provided to implement all the listeners managed by the Tree data source. This adapter also interfaces a DefaultTreeModel to synchronize the data source with this tree model, according to Rogue Wave Server notifications, and with the modification events that occur on the tree models.
