DESCRIPTION

       This is the abstract base class from which all scene graph node classes are derived.

METHODS

     void                setOverride(SbBool state)
          Turns override flag on or off.

     SbBool              isOverride() const
          Returns the state of the override flag.

     SoNode *            copy(SbBool copyConnections = FALSE) const
          Creates and returns an exact copy of the node. If the node is a group,  it  copies  the
          children  as well. If copyConnections is TRUE (it is FALSE by default), any connections
          to (but not from) fields of the node are copied, as well. Note that multiple references
          to a node under the node to be copied will result in multiple references to the copy of
          that node.

     virtual SbBool      affectsState() const
          Returns TRUE if a node has an effect on the state during traversal. The default  method
          returns  TRUE.  Node  classes (such as SoSeparator) that isolate their effects from the
          rest of the graph override this method to return FALSE.

     static SoNode *     getByName(const SbName &name)
     static int          getByName(const SbName &name, SoNodeList &list)
          A node's name can be set using SoBase::setName().  These  methods  allow  nodes  to  be
          looked  up  by  name. The first one returns the last node given the specified name. The
          second one returns the number of nodes with the given name, and adds to  list  pointers
          to those nodes.

     static SoType       getClassTypeId()
          Returns type identifier for the SoNode class.

ACTION BEHAVIOR

       SoSearchAction
          If  the  node pointer, type, or name matches the search criteria, returns a path to the
          node.

     SoWriteAction
          Writes the contents of the node to the current SoOutput.

FILE FORMAT/DEFAULTS

       This is an abstract class. See the reference page of a derived class for  the  format  and
       default values.
