the class FluoQueryMetadataDAO method readProjectionMetadataBuilder.

private ProjectionMetadata.Builder readProjectionMetadataBuilder(final SnapshotBase sx, final String nodeId) {
    requireNonNull(sx);

    final String rowId = nodeId;
    final Map<Column, String> values = sx.gets(rowId, FluoQueryColumns.PROJECTION_VARIABLE_ORDER, FluoQueryColumns.PROJECTION_PROJECTED_VARS, FluoQueryColumns.PROJECTION_PARENT_NODE_ID, FluoQueryColumns.PROJECTION_CHILD_NODE_ID);
    // Return an object holding them.
    final String varOrderString = values.get(FluoQueryColumns.PROJECTION_VARIABLE_ORDER);
