Hi Kim,
You may just use the osgDB::Registry cache. That's automatic :)
For instance, set the cache by writing:
osgDB::ReaderWriter::Options* rwoptions = new
osgDB::ReaderWriter::Options;
rwoptions->setObjectCacheHint(osgDB::ReaderWriter::Options::CACHE_ALL);
osgDB::Registry::instance()->setOptions(rwoptions);
This will cache everything loaded with readNodeFile() or readImageFile().
For my use, I preload things in the cache by calling:
osgDB::Registry::instance()->addEntryToObjectCache(path,
osgDB::readNodeFile(path));
And I set the cache to never unload:
osgDB::DatabasePager * pPager = viewer.getDatabasePager();
assert(pPager);
osgDB::Registry::instance()->setDatabasePager(pPager);
pPager->setExpiryDelay(DBL_MAX);
pPager->setExpiryFrames(INT_MAX);
Also, you could clear the cache by calling:
osgDB::Registry::instance()->clearObjectCache();
Hope it will help.
