Public Methods
public
abstract
Connection
getConnection
()
Retrieves the Connection object that was passed to this
RowSet object.
Returns
- the
Connection object passed to the rowset
or null if none was passed
public
abstract
ResultSet
getOriginal
()
Retrieves a ResultSet object containing the original
value of this RowSet object.
The cursor is positioned before the first row in the result set.
Only rows contained in the result set returned by the method
getOriginal are said to have an original value.
Returns
- the original value of the rowset
public
abstract
ResultSet
getOriginalRow
()
Retrieves a ResultSet object containing the original value
of the current row only. If the current row has no original value,
an empty result set is returned. If there is no current row,
an exception is thrown.
Returns
- the original value of the current row as a
ResultSet
object
Throws
| SQLException |
if a database access error occurs or this method
is called while the cursor is on the insert row, before the
first row, or after the last row
|
public
abstract
Object[]
getParams
()
Retrieves the parameters that have been set for this
RowSet object's command.
Returns
- an array of the current parameter values for this
RowSet
object's command
Sets the given RowSetMetaData object as the
RowSetMetaData object for this RowSet
object. The RowSetReader object associated with the rowset
will use RowSetMetaData methods to set the values giving
information about the rowset's columns.
Parameters
| md |
the RowSetMetaData object that will be set with
information about the rowset's columns |
