javax.sql.RowSetReader
An interface which provides functionality for a disconnected RowSet to get
data from a data source 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.
Summary
Details
Public Methods
public
void
readData(RowSetInternal theCaller)
Reads new data into the 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.
Parameters
theCaller
| must be the calling RowSet object, which must have implemented
the RowSetInternal interface. |
Throws
SQLException
| if a problem occurs accessing the database or if the Reader
calls the RowSet.execute method.
