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.
