OpenJDK 27 · javax.sql.rowset.serial.SerialDatalink · APIdia, the JavaDoc alternative

A serialized mapping in the Java programming language of an SQL DATALINK value. A DATALINK value references a file outside of the underlying data source that the data source manages.

RowSet implementations can use the method RowSet.getURL to retrieve a java.net.URL object, 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.
