public interface RowSetReader
RowSet
to get data from a database into its rows. The RowSet calls the
RowSetReader interface when the RowSet's execute method is
invoked - a RowSetReader must first be registered with the RowSet for this to work.RowSet| Modifier and Type | Method and Description |

void |
readData(RowSetInternal theCaller)
Reads new data into the
RowSet. |
void readData(RowSetInternal theCaller) throws SQLException
RowSet. The calling RowSet object
must itself implement the RowSetInternal interface and the
RowSetReader must be registered as a reader on the
RowSet.
This method adds rows into the calling RowSet. The reader may
invoke any of the RowSet's methods except for the execute
method (calling execute will cause an SQLException to be
thrown). However, when the reader calls the RowSet's methods, no
events are sent to listeners - any listeners are informed by the calling
RowSet's execute method once the reader returns from the
readData method.
theCaller - must be the calling RowSet object, which must have
implemented the RowSetInternal interface.SQLException - if a problem occurs accessing the database or if the reader
calls the RowSet.execute() method.RowSetInternal
