void osgGA::EventVisitor::removeEvent ( GUIEventAdapter * event )

virtual void osgGA::EventVisitor::reset ( ) [virtual]

Method to call to reset visitor.
Useful if your visitor accumulates state during a traversal, and you plan to reuse the visitor. To flush that state for the next traversal: call reset() prior to each traversal.
Reimplemented from osg::NodeVisitor.
