org.datanucleus.store.mapped.mapping.EmbeddedPCMapping
Mapping for a PC object embedded within another PC object (1-1 relation). Provides mapping for a single Java type (the PC type) to multiple datastore columns. Allows for nested embedded fields. Implements MappingCallbacks since if we are embedding a MappingCallbacks field (e.g a BLOB on Oracle) then we need in turn to call the underlying MappingCallbacks methods.

            AbstractMemberMetaData fmd = (AbstractMemberMetaData) iter.next();
            JavaTypeMapping fieldMapping = memberMappingsMap.get(fmd);
            if (fieldMapping instanceof EmbeddedPCMapping)
            {
                // Add indexes for fields of this embedded PC object
                EmbeddedPCMapping embMapping = (EmbeddedPCMapping)fieldMapping;
                for (int i=0;i<embMapping.getNumberOfJavaTypeMappings();i++)
                {
                    JavaTypeMapping embFieldMapping = embMapping.getJavaTypeMapping(i);
                    IndexMetaData imd = embFieldMapping.getMemberMetaData().getIndexMetaData();
                    if (imd != null)
                    {
                        Index index = TableUtils.getIndexForField(this, imd, embFieldMapping);
                        if (index != null)
