Examples of org.rssowl.ui.internal.util.TreeTraversal

org.rssowl.ui.internal.util.TreeTraversal
An abstract helper-class to perform navigation in a Tree, specified by a ITreeNode as starting point. Implementors have to override the select(ITreeNode)-Method allowing to filter certain Nodes from the navigation. @author bpasero
