Description copied from interface: MetaDataFactory

Load metadata for the given class in the given mode(s). If loading in MetaDataModes.MODE_QUERY, the class may be null. Loaded metadata should be added directly to the repository. It should have its source mode set appropriately via ClassMetaData.setSourceMode(int).

Specified by:

load in interface MetaDataFactory

mode - the mode to load metadata in: if mapping information is stored together with metadata, then you can load mapping data even if this mode only includes MODE_META, so long as the strict property hasn't been set

false if this factory is unable to store metadata
