use of javax.jdo.metadata.JoinMetadata in project motech by motech.

the class EntityMetadataBuilderImpl method setMapMetadata.

private FieldMetadata setMapMetadata(ClassMetadata cmd, EntityDto entity, FieldDto field, Class<?> definition, EntityType entityType) {
    FieldMetadata fmd = cmd.newFieldMetadata(getNameForMetadata(field));

    MetadataDto valueMetadata = field.getMetadata(MAP_VALUE_TYPE);
    boolean serialized = shouldSerializeMap(keyMetadata, valueMetadata);
    // Depending on the types of key and value of the map we either serialize the map or create a separate table for it
    fmd.setSerialized(serialized);
    addDefaultFetchGroupMetadata(fmd, definition);
    MapMetadata mmd = fmd.newMapMetadata();
    if (serialized) {
        mmd.setSerializedKey(true);
