Class SoNodeDependencies

java.lang.Object
com.openinventor.inventor.Inventor
com.openinventor.inventor.caches.SoNodeDependencies
All Implemented Interfaces:
SafeDisposable
public class SoNodeDependencies extends Inventor implements SafeDisposable
This class is a cache handler that can be used to monitor the modifications made to elements or fields. In order to add new Elements or Fields to be monitored by the cache, use the appropriate addDependency() method.

If one of the added elements or fields has been modified since the last call to updateCache(), the isValid() method will return false, and a subsequent call to updateCache() will make it valid again.

Additionnally, the handled cache can be manually invalidated using the invalidate() method.
