Description copied from interface: MetaDataFactory
Store the given metadata.

Specified by:
store in interface MetaDataFactory
Overrides:

Specified by:
drop in interface MetaDataFactory
Overrides:
drop in class AbstractMetaDataFactory
Returns:
false if any metadata could not be dropped

isMappingOnlyFactory

protected boolean isMappingOnlyFactory()
