makVrv::DtTerrainPageSignaler Class Reference

It is expected that custom implementations of paging (whether inheriting from pagedLOD or not, should use this signaler to notify interested clients about paging events. See example usage in DtMetaflightGroup, DtHierarchicalPagedLod.

Constructor & Destructor Documentation

virtual makVrv::DtTerrainPageSignaler::~DtTerrainPageSignaler ( )

virtual

DTOR.

makVrv::DtTerrainPageSignaler::DtTerrainPageSignaler ( )

protected

protected default constructor so it can only be constructed by the instance static function

Member Function Documentation

static DtTerrainPageSignaler& makVrv::DtTerrainPageSignaler::instance ( DtDe &  )

static

Get the global instance for this signaler.

static void makVrv::DtTerrainPageSignaler::registerInstance ( DtDe &  de, DtTerrainPageSignaler *    )

static

virtual void makVrv::DtTerrainPageSignaler::setSignalsEnabled ( bool  enable )

virtual

If enable is false the signals above are not raised. Used internally.

virtual bool makVrv::DtTerrainPageSignaler::signalsEnabled ( void  ) const

virtual

Have the signals been enabled? Used internally.

Member Data Documentation

boost::signalslib::signal<void(const osg::Group* page, const osg::Node* child, const std::string& fileName, osg::Node*& returnedNode)> makVrv::DtTerrainPageSignaler::signal_childLoaded

signal when a child is loaded, but not yet added to the scenegraph

boost::signalslib::signal<void(const osg::Group* page, const osg::Node* child)> makVrv::DtTerrainPageSignaler::signal_childPagedIn

signal when a child is paged in (i.e. added to the scenegraph)

boost::signalslib::signal<void(const osg::Group* page, const osg::Node* child)> makVrv::DtTerrainPageSignaler::signal_childAboutToPageOut

signal when a child is about to be paged out (i.e. data corresponding to it unloaded and the child removed from the scenegraph)
