Package org.aksw.r2rml.jena.jdbc.impl

Class RowToNodeViaTypeManager

java.lang.Object

org.aksw.r2rml.jena.jdbc.impl.RowToNodeViaTypeManager

All Implemented Interfaces:

NodeMapper

public class RowToNodeViaTypeManager
extends Object
implements NodeMapper

Generic mapper that retrieves each column's value as a Object and then request an appropriate RDFDatatype from Jena's TypeMapper. The advantage of this approach is the robustness and independence of SQL type information. The disadvantage is the performance impact by going through the type mapper on every invocation of map.
