Detailed Description

       The SoSimplifyAction class is the base class for the simplify action classes.

Constructor & Destructor Documentation

   SoSimplifyAction::SoSimplifyAction (void)
       A constructor.

   SoSimplifyAction::~SoSimplifyAction (void) [virtual]
       The destructor.

Member Function Documentation

   SoType SoSimplifyAction::getTypeId (void) const [virtual]
       Returns the type identification of an action derived from a class inheriting SoAction.
       This is used for run-time type checking and 'downward' casting.

       Usage example:

       void bar(SoAction * action)
       {
         if (action->getTypeId() == SoGLRenderAction::getClassTypeId()) {
           // safe downward cast, know the type
           SoGLRenderAction * glrender = (SoGLRenderAction *)action;
         }
         return; // ignore if not renderaction
       }

       For application programmers wanting to extend the library with new actions: this method
       needs to be overridden in all subclasses. This is typically done as part of setting up the
       full type system for extension classes, which is usually accomplished by using the pre-
       defined macros available through Inventor/nodes/SoSubAction.h: SO_ACTION_SOURCE,
       SO_ACTION_INIT_CLASS and SO_ACTION_CONSTRUCTOR.

       For more information on writing Coin extensions, see the SoAction class documentation.

       Returns the actual type id of an object derived from a class inheriting SoAction. Needs to
       be overridden in all subclasses.

       Implements SoAction.

       Reimplemented in SoGlobalSimplifyAction, SoShapeSimplifyAction, and SoReorganizeAction.

   void SoSimplifyAction::addMethod (const SoTypetype, SoActionMethodmethod) [static]
       This API member is considered internal to the library, as it is not likely to be of
       interest to the application programmer.

   void SoSimplifyAction::enableElement (const SoTypetype, const intstackindex) [static]
       This API member is considered internal to the library, as it is not likely to be of
       interest to the application programmer.

   const SoEnabledElementsList & SoSimplifyAction::getEnabledElements (void) const [protected],
       [virtual]
       Returns a list of the elements used by action instances of this class upon traversal
       operations.

       Reimplemented from SoAction.

       Reimplemented in SoGlobalSimplifyAction, SoShapeSimplifyAction, and SoReorganizeAction.

   void SoSimplifyAction::apply (SoNode *root) [virtual]
       Applies the action to the scene graph rooted at root.

       Note that you should not apply an action to a node with a zero reference count. The
       behavior in that case is undefined.

       Reimplemented from SoAction.

       Reimplemented in SoReorganizeAction.

   void SoSimplifyAction::apply (SoPath *path) [virtual]
       Applies the action to the parts of the graph defined by path.

       Note that an SoPath will also contain all nodes that may influence e.g. geometry nodes in
       the path. So for instance applying an SoGLRenderAction on an SoPath will render that path
       as expected in the view, where geometry will get its materials, textures, and other
       appearance settings correctly.

       If the path ends in an SoGroup node, the action will also traverse the tail node's
       children.

       Reimplemented from SoAction.

       Reimplemented in SoReorganizeAction.

   void SoSimplifyAction::apply (const SoPathList &pathlist, SbBoolobeysrules = FALSE) [virtual]
       Applies action to the graphs defined by pathlist. If obeysrules is set to TRUE, pathlist
       must obey the following four conditions (which is the case for path lists returned from
       search actions for non-group nodes and path lists returned from picking actions):

       All paths must start at the same head node. All paths must be sorted in traversal order.
       The paths must be unique. No path can continue through the end point of another path.

       See Also:
           SoAction::apply(SoPath * path)

       Reimplemented from SoAction.

       Reimplemented in SoReorganizeAction.

   void SoSimplifyAction::beginTraversal (SoNode *node) [protected],  [virtual]
       This virtual method is called from SoAction::apply(), and is the entry point for the
       actual scenegraph traversal.

       It can be overridden to initialize the action at traversal start, for specific
       initializations in the action subclasses inheriting SoAction.

       Default method just calls traverse(), which any overridden implementation of the method
       must do too (or call SoAction::beginTraversal()) to trigger the scenegraph traversal.
