<DL>
<DD>It seems kind of dumb that the reference to the tree model is passed in
 seperately - but know that this is actually necessary.  There is a really 
 weird chicken before the egg problem.  You cannot create a TreeModel without
 giving it its root node.  However, the nodes in your tree can't update the 
 structure of the tree unless they have a reference to the TreeModel.  So in 
 the end this was the only compromise that I could get to work well

<A NAME="updateTree()"><!-- --></A><H3>
updateTree</H3>
<PRE>
public void <B>updateTree</B>()</PRE>
<DL>
<DD>This method uses introspection to programatically discover all of 
 the parameters for this generic object.  For each one of them it
 uses the TreeModel reference to create a new subtree to represent
 that parameter and its value ranges.  Note that all of these nodes
 are PropertyNodes which themselves hold the logic of figuring out
 what type of parameter it is they are representing and thus what 
 type of subtree to build.
 <p/> 
 We need to be careful because this was molded from the code inside of 
 the PropertySheetPanel class.  Which means that we are wide open
 to copy/paste problems.  In the future, when that code changes to 
 adapt to other changes in Weka then this could easily become broken.

<DD>This method is responsible for returning all possible values through 
 a recursive loop.
 
 When the recursion terminates that means that there are no more parameter
 sets to branch out through so all we have to do is save the current Vector
 in the working set of combinations.  Otherwise we iterate through all 
 possible values left in the next set of parameter values and recursively
 call this function.
