Member Function Documentation

virtual void makVrv::DtStreamedFeatureManager::addStreamedFeatureCreator ( const std::string &  registrantName, const std::string &  styleName, DtStreamedFeatureCreator *  creator  )

virtual

Register a creator to be called when features are streamed in.

Parameters

registrantName	is a name given by the registrant to identify features created by that registrant (for later deletion)
styleName	styleName is the name provided in the .osgEarth style block that this creator is interested in. When features are streamed in from a style block with this name, the registered creator will be called.
creator	is a pointer to a DtStreamedFeatureCreator implementation

virtual void makVrv::DtStreamedFeatureManager::checkAndProcessStrandedFeatures ( )

pure virtual

Method called by the sceneDriver tick to process any features that need to be deleted.

This method is mutex-protected, since features are placed on the stranded list from osgEarth paging threads (and the list will be processed in the render thread).

Implemented in makVrv::DtOsgEarthStreamedFeatureManager.
