- All Implemented Interfaces:
- Serializable, Cloneable
public class SerialDatalink extends Object implements Serializable, Cloneable
A serialized mapping in the Java programming language of an SQLDATALINKvalue. ADATALINKvalue references a file outside of the underlying data source that the data source manages.RowSetimplementations can use the methodRowSet.getURLto retrieve ajava.net.URLobject, which can be used to manipulate the external data.java.net.URL url = rowset.getURL(1);
Thread safety
A SerialDatalink is not safe for use by multiple concurrent threads. If a SerialDatalink is to be used by more than one thread then access to the SerialDatalink should be controlled by appropriate synchronization.- See Also:
