SoAction — abstract base class for all actions

SoAction  is  the abstract base class for all actions. Classes derived from SoAction define operations to
       be applied at each node encountered during traversal of a scene graph. The function that gets  called  to
       implement the action for a particular node type is determined by a lookup table in the global database.

       SoAction

virtual~SoAction()
          Destructor.

     virtualvoidapply(SoNode*node)virtualvoidapply(SoPath*path)virtualvoidapply(constSoPathList&pathList,SbBoolobeysRules=FALSE)
          Initiates  an action on the graph defined either by a node, path, or list of paths. TRUE can be passed
          for the obeysRules flag if the given path list has the following 4 properties:

               1 - All paths have the same head node
               2 - Paths are sorted in traversal order
               3 - If one path ends at node A, no other path
                   continues through A
               4 - No two paths are the same

          These rules will be obeyed by path lists returned by picking and by searches for non-group nodes.

     staticSoTypegetClassTypeId()
          Returns the type identifier for this class.

     virtualSoTypegetTypeId()
          Returns the type identifier for a specific instance.

     virtualSbBoolisOfType(SoTypetype)
          Returns TRUE if this instance is of the  type  specified  in  type  or  is  derived  from  that  type.
          Otherwise, it returns FALSE. For example,
               actionPtr->isOfType(SoGetMatrixAction::getClassTypeId())

          returns TRUE if actionPtr is an instance of SoGetMatrixAction or one of its subclasses.

     virtualvoidinvalidateState()
          Invalidates  the  current traversal state in the action, forcing it to be recreated when the action is
          next applied. This is typically unnecessary in most applications.
