.PP 
The \fBSoLabel\fP class is a node for holding label information in a scene graph\&.
.PP
Use this node as a convenient way of labeling nodes or subgraphs within a scene graph\&. 

\fBSoLabel\fP nodes does not influence traversal in any way for any of the builtin actions\&.

.PP
Returns the type identification of an object derived from a class inheriting \fBSoBase\fP\&. This is used for run-time type checking and 'downward' casting\&. Usage example:
.PP
.PP
.nf
void foo(SoNode * node)
{
  if (node->getTypeId() == SoFile::getClassTypeId()) {
    SoFile * filenode = (SoFile *)node;  // safe downward cast, knows the type
  }
}
.fi

.PP
For application programmers wanting to extend the library with new nodes, engines, nodekits, draggers or others: this method needs to be overridden in \fIall\fP 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 for instance \fBInventor/nodes/SoSubNode\&.h\fP (SO_NODE_INIT_CLASS and SO_NODE_CONSTRUCTOR for node classes), Inventor/engines/SoSubEngine\&.h (for engine classes) and so on\&.
.PP

.PP
Implements \fBSoBase\fP\&.
.SS "const \fBSoFieldData\fP ** SoLabel::getFieldDataPtr (void)\fC [static]\fP, \fC [protected]\fP"
\fIThis API member is considered internal to the library, as it is not likely to be of interest to the application programmer\&.\fP 
.PP
Reimplemented from \fBSoNode\fP\&.
.SS "const \fBSoFieldData\fP * SoLabel::getFieldData (void) const\fC [protected]\fP, \fC [virtual]\fP"
Returns a pointer to the class-wide field data storage object for this instance\&. If no fields are present, returns \fCNULL\fP\&. 
.PP
Reimplemented from \fBSoFieldContainer\fP\&.
