DESCRIPTION

53       This is the abstract base class from which all scene graph node classes
54       are derived.
55

METHODS

57     void                setOverride(SbBool state)
58          Turns override flag on or off.
59
60     SbBool              isOverride() const
61          Returns the state of the override flag.
62
63     SoNode *            copy(SbBool copyConnections = FALSE) const
64          Creates and returns an exact copy of the node.  If  the  node  is  a
65          group,  it  copies  the children as well. If copyConnections is TRUE
66          (it is FALSE by default), any connections to (but not  from)  fields
67          of  the node are copied, as well. Note that multiple references to a
68          node under the node to be copied will result in multiple  references
69          to the copy of that node.
70
71     virtual SbBool      affectsState() const
72          Returns  TRUE if a node has an effect on the state during traversal.
73          The default method returns TRUE. Node classes (such as  SoSeparator)
74          that  isolate their effects from the rest of the graph override this
75          method to return FALSE.
76
77     static SoNode *     getByName(const SbName &name)
78     static int          getByName(const SbName &name, SoNodeList &list)
79          A node's name can be set  using  SoBase::setName().   These  methods
80          allow  nodes to be looked up by name. The first one returns the last
81          node given the specified name. The second one returns the number  of
82          nodes with the given name, and adds to list pointers to those nodes.
83
84     static SoType       getClassTypeId()
85          Returns type identifier for the SoNode class.
86
87

ACTION BEHAVIOR

89       SoSearchAction
90          If  the  node  pointer,  type,  or name matches the search criteria,
91          returns a path to the node.
92
93     SoWriteAction
94          Writes the contents of the node to the current SoOutput.
95
96

FILE FORMAT/DEFAULTS

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