virtual bool makVrv::DtVirtualProgramCache::findAndSetOn ( const std::string &  strHash, osg::StateSet *  stateSet  )

virtual

Find a vp with a hash and set it on the state set, if found. This was just a find returning a raw VP and that can get deleted from underneath/multi-threaded (was happening in cdb). The internal lock prevents this from happening.

virtual void makVrv::DtVirtualProgramCache::cache ( const std::string &  strHash, osgEarth::VirtualProgram *  virtualProgram  )

virtual

cache a virtual program with the given hash

virtual void makVrv::DtVirtualProgramCache::slot_reloadShaders ( void  )

pre loading function

virtual void makVrv::DtVirtualProgramCache::clear ( )

clear internal cache
