示例1: convertToBindings
import com.hp.hpl.jena.sparql.engine.binding.BindingFactory; //导入依赖的package包/类
/** Convert rows to bindings for a give parent, that may, or may not,
* have equivalent bindings of variables in the rows */

public Binding convert(Row<NodeId> row) {
if ( parent.isEmpty() )
return new BindingRow(row, nodeTable) ;
// Temporary fix. Proper fix is to change BindingBase to allow multiple occurrences in a controlled way.
BindingMap b = BindingFactory.create() ;
