Inheritance diagram for osgDB::Registry:
The RegisterDotOsgWrapperProxy can be used to automatically register DotOsgWrappers, at runtime with the Registry. A DotOsgWrapper encapsulates the functions that can read and write to the .osg for each osg::Object.
The RegisterReaderWriterProxy can be used to automatically register at runtime a reader/writer with the Registry.

void osgDB::Registry::updateTimeStampOfObjectsInCacheWithExtenalReferences | ( | double | currentTime | ) |
For each object in the cache which has an reference count greater than 1 (and therefore referenced by elsewhere in the application) set the time stamp for that object in the cache to specified time. This would typically be called once per frame by applications which are doing database paging, and need to prune objects that are no longer required. Time value is time in sceonds.
void osgDB::Registry::removeExpiredObjectsInCache | ( | double | expiryTime | ) |
Removed object in the cache which have a time stamp at or before the specified expiry time. This would typically be called once per frame by applications which are doing database paging, and need to prune objects that are no longer required, and called after the a called after the call to updateTimeStampOfObjectsInCacheWithExtenalReferences(currentTime). Note, the currentTime is not the expiryTime, one would typically set the expiry time to a fixed amount of time before currentTime, such as expiryTime = currentTime-10.0.
