osg::Node * KMLReader::read	(	std::istream &	in,
		const URIContext &	context
	)

Reads KML from a stream and returns a node

Definition at line 35 of file KMLReader.cpp.

{
    // read the KML from an XML stream:
    osg::ref_ptr<XmlDocument> xml = XmlDocument::load( in, context );
    if ( !xml.valid() )
        return 0L;

    // convert to a config:
    Config config = xml->getConfig();

    osg::Node* node = read( config );
    node->setName( context.referrer() );

    return node;
}
