Examples of DataTree

org.apache.zookeeper.server.DataTree
This class maintains the tree data structure. It doesn't have any networking or client connection code in it so that it can be tested in a stand alone way.
The tree maintains two parallel data structures: a hashtable that maps from full paths to DataNodes and a tree of DataNodes. All accesses to a path is through the hashtable. The tree is traversed only when serializing to disk.

org.jitterbit.integration.client.ui.interchange.entity.transformation.tree.utils.DataTree
Represents the data that has been loaded into a mapping tree's source or target tree.
The data tree can be displayed simultaneously by several TreeComponents, for example both the mapping tree's source component and the formula builder's source tree. This class handles the communication between these trees, keeping things like the current data instances in sync. It also provides change notifications, that can be used e.g. to update the displayed test values in the formula builder's test section. @author Torgil Zethson @since 4.0.0
