Searches for nodes in the scene graph step by step.
This class extends SoSearchAction. This class allows the user to add a callback to control which paths are added to the path list. This user callback is called just before the found path would be added to the list. It determines whether or not the path will be added to the list. The use of this class is particularly interesting when the found paths are potentially numerous and the user wants to filter the returned path list to retrieve only some of them.
