source: osgVisual/trunk/include/object/object_updater.h @ 179

Last change on this file since 179 was 88, checked in by Torben Dannhauer, 14 years ago

Moved memory leak detection from source file to headerfile. Its still in the class but at least not in the source file.

The leak detection works, but the false positives are not stopped.
Use Linux/Valgrind? to make your final leak detection beyond the easy first approach in MSVC

28 * \brief This class is the base class for visual_object updater.
29 *
30 * This base implementation updates the object position with the slotnames
31 *  object_->getName()+"_POS_LAT", object_->getName()+"_POS_LON", object_->getName()+"_POS_ALT",
32 * object_->getName()+"_ROT_X", object_->getName()+"_ROT_Y", object_->getName()+"_ROT_Z",
33 *
34 * To implement custom updaters, please derive from this class and overwrite the functions preUpdate(..) and postUpdate(..).
35 * Take care to call nested preUpdater and postUpdater to allow updater chains.
