public CachedRowSetImpl()
throws java.sql.SQLException
CachedRowSetImpl object with
the capacity to hold 100 rows. This new object has no metadata
and has the following default values:
onInsertRow = false
insertRow = null
cursorPos = 0
numRows = 0
showDeleted = false
queryTimeout = 0
maxRows = 0
maxFieldSize = 0
rowSetType = ResultSet.TYPE_SCROLL_INSENSITIVE

readOnly = false
isolation = Connection.TRANSACTION_READ_COMMITTED
escapeProcessing = true
onInsertRow = false

A CachedRowSetImpl object is configured to use the default
RIOptimisticProvider implementation to provide connectivity
and synchronization capabilities to the set data source.
java.sql.SQLException - if an error occurs
public CachedRowSetImpl(java.util.Hashtable env)
throws java.sql.SQLException
CachedRowSetImpl instance with the same default properties as
as the zero parameter constructor.
onInsertRow = false

cursorPos = 0
absolutePos = 0

However, applications will have the means to specify at runtime the
desired SyncProvider object.
For example, creating a CachedRowSetImpl object as follows ensures
that a it is established with the com.foo.provider.Impl synchronization
implementation providing the synchronization mechanism for this disconnected
RowSet object.
Hashtable env = new Hashtable();
env.put(javax.sql.rowset.spi.SyncFactory.ROWSET_PROVIDER_NAME,
"com.foo.provider.Impl");
CachedRowSetImpl crs = new CachedRowSet(env);
Calling this constructor with a null parameter will
cause the SyncFactory to provide the reference
optimistic provider com.sun.rowset.providers.RIOptimisticProvider.
In addition, the following properties can be associated with the provider to assist in determining the choice of the synchronizaton provider such as:
ROWSET_SYNC_PROVIDER - the property specifying the the
SyncProvider class name to be instantiated by the
SyncFacttory
ROWSET_SYNC_VENDOR - the property specifying the software
vendor associated with a SyncProvider implementation.
ROWSET_SYNC_PROVIDER_VER - the property specifying the
version of the SyncProvider implementation provided by the
software vendor.

if any, that were set for the previous command.
The command property may not be needed
if the rowset is produced by a data source, such as a spreadsheet,
that does not support commands. Thus, this property is optional
and may be null.

public void populate(java.sql.ResultSet data)
throws java.sql.SQLException
CachedRowSetImpl object with data from
the given ResultSet object. This
method is an alternative to the method execute
for filling the rowset with data. The method populate
does not require that the properties needed by the method
execute, such as the command property,
be set. This is true because the method populate
is given the ResultSet object from
which to get data and thus does not need to use the properties
required for setting up a connection and executing this
CachedRowSetImpl object's command.
After populating this rowset with data, the method
populate sets the rowset's metadata and
then sends a RowSetChangedEvent object
to all registered listeners prior to returning.

NoteIn the reference implementation an optimistic concurrency implementation
is provided as a sample implementation of a the SyncProvider
abstract class.
This method fails if any of the updates cannot be propagated back to the data source. When it fails, the caller can assume that none of the updates are reflected in the data source. When an exception is thrown, the current row is set to the first "updated" row that resulted in an exception unless the row that caused the exception is a "deleted" row. In that case, when deleted rows are not shown, which is usually true, the current row is not affected.
If no SyncProvider is configured, the reference implementation
leverages the RIOptimisticProvider available which provides the
default and reference synchronization capabilities for disconnected
RowSets.

This form of the method uses the rowset's user, password, and url or
data source name properties to create a database
connection. If properties that are needed
have not been set, this method will throw an exception.
Another form of this method uses an existing JDBC Connection
object instead of creating a new one; therefore, it ignores the
properties used for establishing a new connection.
The query specified by the command property is executed to create a
ResultSet object from which to retrieve data.
The current contents of the rowset are discarded, and the
rowset's metadata is also (re)set. If there are outstanding updates,
they are also ignored.
The method execute closes any database connections that it
creates.

next moves the cursor to the first row, making it
the current row; the second call makes the second row the
current row, and so on.
If an input stream from the previous row is open, it is
implicitly closed. The ResultSet object's warning

This method handles the cases where the cursor moves to a row that has been deleted. If this rowset shows deleted rows and the cursor moves to a row that has been deleted, this method moves the cursor to the next row until the cursor is on a row that has not been deleted.
The method internalNext is called by methods such as
next, absolute, and relative,
and, as its name implies, is only called internally.

public java.lang.String getCursorName()
throws java.sql.SQLException
CachedRowSetImpl object.
In SQL, a result table is retrieved through a cursor that is
named. The current row of a ResultSet can be updated or deleted
using a positioned update/delete statement that references the
cursor name. To ensure that the cursor has the proper isolation
level to support an update operation, the cursor's SELECT
statement should be of the form select for update.
If the for update clause
is omitted, positioned updates may fail.
JDBC supports this SQL feature by providing the name of the
SQL cursor used by a ResultSet object. The current row
of a result set is also the current row of this SQL cursor.
Note: If positioned updates are not supported, an
SQLException is thrown.

CachedRowSetImpl object's cursor to the row number
specified.
If the number is positive, the cursor moves to an absolute row with
respect to the beginning of the rowset. The first row is row 1, the second
is row 2, and so on. For example, the following command, in which
crs is a CachedRowSetImpl object, moves the cursor
to the fourth row, starting from the beginning of the rowset.
crs.absolute(4);
If the number is negative, the cursor moves to an absolute row position
with respect to the end of the rowset. For example, calling
absolute(-1) positions the cursor on the last row,
absolute(-2) moves it on the next-to-last row, and so on.
If the CachedRowSetImpl object crs has five rows,
the following command moves the cursor to the fourth-to-last row, which
in the case of a rowset with five rows, is also the second row, counting
from the beginning.
crs.absolute(-4);
If the number specified is larger than the number of rows, the cursor
will move to the position after the last row. If the number specified
would move the cursor one or more rows before the first row, the cursor
moves to the position before the first row.
Note: Calling absolute(1) is the same as calling the
method first(). Calling absolute(-1) is the
same as calling last().
absolute in interface java.sql.ResultSetrow - a positive number to indicate the row, starting row numbering from
the first row, which is 1; a negative number to indicate
the row, starting row numbering from the last row, which is

public boolean relative(int rows)
throws java.sql.SQLException
If the number is positive, the cursor moves the specified number of
rows toward the end of the rowset, starting at the current row.
For example, the following command, in which
crs is a CachedRowSetImpl object with 100 rows,
moves the cursor forward four rows from the current row. If the
current row is 50, the cursor would move to row 54.
crs.relative(4);
If the number is negative, the cursor moves back toward the beginning
the specified number of rows, starting at the current row.
For example, calling the method
absolute(-1) positions the cursor on the last row,
absolute(-2) moves it on the next-to-last row, and so on.
If the CachedRowSetImpl object crs has five rows,
the following command moves the cursor to the fourth-to-last row, which
in the case of a rowset with five rows, is also the second row
from the beginning.
crs.absolute(-4);
If the number specified is larger than the number of rows, the cursor
will move to the position after the last row. If the number specified
would move the cursor one or more rows before the first row, the cursor
moves to the position before the first row. In both cases, this method
throws an SQLException.
Note: Calling absolute(1) is the same as calling the
method first(). Calling absolute(-1) is the
same as calling last(). Calling relative(0)
is valid, but it does not change the cursor position.

public boolean previous()
throws java.sql.SQLException
CachedRowSetImpl object's cursor to the
previous row and returns true if the cursor is on
a valid row or false if it is not.
This method also notifies all listeners registered with this
CachedRowSetImpl object that its cursor has moved.
Note: calling the method previous() is not the same
as calling the method relative(-1). This is true
because it is possible to call previous() from the insert
row, from after the last row, or from the current row, whereas
relative may only be called from the current row.
The method previous may used in a while
loop to iterate through a rowset starting after the last row
and moving toward the beginning. The loop ends when previous
returns false, meaning that there are no more rows.
For example, the following code fragment retrieves all the data in
the CachedRowSetImpl object crs, which has
three columns. Note that the cursor must initially be positioned
after the last row so that the first call to the method
previous places the cursor on the last line.
crs.afterLast();
while (previous()) {
String name = crs.getString(1);
int age = crs.getInt(2);
short ssn = crs.getShort(3);
System.out.println(name + " " + age + " " + ssn);
}
This method throws an SQLException if the cursor is not
on a row in the rowset, before the first row, or after the last row.

to the insert row. The current row in the rowset is remembered
while the cursor is on the insert row.
The insert row is a special row associated with an updatable
rowset. It is essentially a buffer where a new row may
be constructed by calling the appropriate updateXXX
methods to assign a value to each column in the row. A complete
row must be constructed; that is, every column that is not nullable
must be assigned a value. In order for the new row to become part
of this rowset, the method insertRow must be called
before the cursor is moved back to the rowset.
Only certain methods may be invoked while the cursor is on the insert
row; many methods throw an exception if they are called while the
cursor is there. In addition to the updateXXX
and insertRow methods, only the getXXX methods
may be called when the cursor is on the insert row. A getXXX
method should be called on a column only after an updateXXX
method has been called on that column; otherwise, the value returned is
undetermined.

This method is an alternative to the method execute
for filling the rowset with data. The method populate
does not require that the properties needed by the method
execute, such as the command property,
be set. This is true because the method populate
is given the ResultSet object from
which to get data and thus does not need to use the properties
required for setting up a connection and executing this
