static CDOCollectionLoadingPolicy

DEFAULT A default collection loading strategy that leads to complete loading of CDOID lists before any of their elements is accessed.

Method Summary

int	getInitialChunkSize() Returns the maximum number of CDOIDs to be loaded for collections when an object is loaded, i.e.
