object.
|
Public methods
getConnection
public abstract Connection getConnection ()
Retrieves the Connection object that was passed to this
RowSet object.
| Returns |
|---|
Connection |
the Connection object passed to the rowset
or null if none was passed |
getOriginal
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 |
|---|
ResultSet |
the original value of the rowset |
getOriginalRow
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 |
|---|
ResultSet |
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 |
getParams
public abstract Object[] getParams ()
Retrieves the parameters that have been set for this
RowSet object's command.
| Returns |
|---|
Object[] |
an array of the current parameter values for this RowSet
object's command |
public abstract void setMetaData (RowSetMetaData md)
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 |
RowSetMetaData: the RowSetMetaData object that will be set with
information about the rowset's columns |
