Experimentation with TreeCache shows that the only thing getKeys returns is the object/objects at that level in the tree.

So if I have objects at

/foo/[objectA]
/foo/[objectB]
/foo/bar/[objectC]

and ask for path /foo I will get two objects. If I ask for "/" or "" I get no objects at all. Is there no way to get the keys for everything in the cache so that I can iterate over all of it?

 public static void main( String[] args )
 {
 BasicConfigurator.configure();

 try
 {
 TreeCache cache = new TreeCache();
 cache.createService();
 cache.startService();

 cache.put("/foo", "foo", new Rectangle() );
 cache.put("/foo", "bar", "Something Else" );
 cache.put("/foo/bar", "barchild", "Child of bar");


 Set children = cache.getChildrenNames("/");
 Set keys = cache.getKeys("/");


 logger.debug("Cache contains ["+ cache.getNumberOfNodes() + "] nodes");
 logger.debug("Children of / are " + children.size() + "[" + children + "]" );
 logger.debug("Cache members are " + cache.getMembers().size() );

 logger.debug("" + keys.size() );
 }
 catch( Exception e )
 {
 logger.error("Something bad happened", e);
 }
 }
