Method Summary

void	clearBranch() clear part of Display scene graph generated by this DataRenderer
void	clearScene() clear any scene graph created by this DataRenderer, and clear all instance variables
boolean	doAction() re-transform if needed; return false if not done
abstract VisADGroup	doTransform() create a VisADGroup scene graph for Data in links; this can put Behavior objects in the scene graph for DataRenderer classes that implement direct manipulation widgets; may reduce work by only changing scene graph for Data and Controls that have changed: 1. use boolean[] changed to determine which Data objects have changed 2. if Data has not changed, then use Control.checkTicks loop like in prepareAction to determine which Control-s have changed
