Class BaseRowSet
java.lang.Objectjavax.sql.rowset.BaseRowSet
- All Implemented Interfaces:
- Serializable, Cloneable
public abstract class BaseRowSet
- extends Object
- implements Serializable, Cloneable
- extends Object
An abstract class providing a RowSet object with its basic functionality.
The basic functions include having properties and sending event notifications,
which all JavaBeansTM components must implement.
1.0 Overview
TheBaseRowSet class provides the core functionality
for all RowSet implementations,
and all standard implementations may use this class in combination with
one or more RowSet interfaces in order to provide a standard
vendor-specific implementation. To clarify, all implementations must implement
at least one of the RowSet interfaces (JdbcRowSet,
CachedRowSet, JoinRowSet, FilteredRowSet,
or WebRowSet). This means that any implementation that extends
the BaseRowSet class must also implement one of the RowSet
interfaces.
The BaseRowSet class provides the following:
- Properties
- Fields for storing current properties
- Methods for getting and setting properties
- Event notification
- A complete set of setter methods for setting the parameters in a
RowSetobject's command - Streams
- Fields for storing stream instances
- Constants for indicating the type of a stream
2.0 Setting Properties
All rowsets maintain a set of properties, which will usually be set using a tool. The number and kinds of properties a rowset has will vary, depending on what theRowSet implementation does and how it gets
its data. For example,
rowsets that get their data from a ResultSet object need to
set the properties that are required for making a database connection.
If a RowSet object uses the DriverManager facility to make a
connection, it needs to set a property for the JDBC URL that identifies the
appropriate driver, and it needs to set the properties that give the
user name and password.
If, on the other hand, the rowset uses a DataSource object
to make the connection, which is the preferred method, it does not need to
set the property for the JDBC URL. Instead, it needs to set the property
for the logical name of the data source along with the properties for
the user name and password.
NOTE: In order to use a DataSource object for making a
connection, the DataSource object must have been registered
with a naming service that uses the Java Naming and Directory
InterfaceTM (JNDI) API. This registration
is usually done by a person acting in the capacity of a system administrator.
3.0 Setting the Command and Its Parameters
When a rowset gets its data from a relational database, it executes a command (a query) that produces aResultSet object. This query is the command that is set
for the RowSet object's command property. The rowset populates itself with data by reading the
data from the ResultSet object into itself. If the query
contains placeholders for values to be set, the BaseRowSet setter methods
are used to set these values. All setter methods allow these values to be set
to null if required.
The following code fragment illustrates how the
CachedRowSetTM
object crs might have its command property set. Note that if a
tool is used to set properties, this is the code that the tool would use.
crs.setCommand("SELECT FIRST_NAME, LAST_NAME, ADDRESS FROM CUSTOMERS" +
"WHERE CREDIT_LIMIT > ? AND REGION = ?");
In this example, the values for CREDIT_LIMIT and
REGION are placeholder parameters, which are indicated with a
question mark (?). The first question mark is placeholder parameter number
1, the second question mark is placeholder parameter number
2, and so on. Any placeholder parameters must be set with
values before the query can be executed. To set these
placeholder parameters, the BaseRowSet class provides a set of setter
methods, similar to those provided by the PreparedStatement
interface, for setting values of each data type. A RowSet object stores the
parameter values internally, and its execute method uses them internally
to set values for the placeholder parameters
before it sends the command to the DBMS to be executed.
The following code fragment demonstrates setting the two parameters in the query from the previous example.
crs.setInt(1, 5000);
crs.setString(2, "West");
If the execute method is called at this point, the query
sent to the DBMS will be:
"SELECT FIRST_NAME, LAST_NAME, ADDRESS FROM CUSTOMERS" +
"WHERE CREDIT_LIMIT > 5000 AND REGION = 'West'"
NOTE: Setting Array, Clob, Blob and
Ref objects as a command parameter, stores these values as
SerialArray, SerialClob, SerialBlob
and SerialRef objects respectively.
4.0 Handling of Parameters Behind the Scenes
NOTE: TheBaseRowSet class provides two kinds of setter methods,
those that set properties and those that set placeholder parameters. The setter
methods discussed in this section are those that set placeholder parameters.
The placeholder parameters set with the
The majority of methods for setting placeholder parameters take two parameters,
with the first parameter
indicating which placeholder parameter is to be set, and the second parameter
giving the value to be set. Methods such as
Several setter methods send the driver and DBMS information beyond the value to be set.

are stored as objects in an internal Hashtable object.
Primitives are stored as their Object type. For example, byte
is stored as Byte object, and int is stored as
an Integer object.
When the method execute is called, the values in the
Hashtable object are substituted for the appropriate placeholder
parameters in the command.
getParams returns the values stored in the
Hashtable object as an array of Object instances.
An element in this array may be a simple Object instance or an
array (which is a type of Object). The particular setter method used
determines whether an element in this array is an Object or an array.
getInt,
getString, getBoolean, and getLong fall into
this category. After these methods have been called, a call to the method
getParams will return an array with the values that have been set. Each
element in the array is an Object instance representing the
values that have been set. The order of these values in the array is determined by the
int (the first parameter) passed to the setter method. The values in the
array are the values (the second parameter) passed to the setter method.
In other words, the first element in the array is the value
to be set for the first placeholder parameter in the RowSet object's
command. The second element is the value to
be set for the second placeholder parameter, and so on.
getParams is called after one of these setter methods has
been used, the elements in the array will themselves be arrays to accommodate the
additional information. In this category, the method setNull is a special case
because one version takes only
two parameters (setNull(int parameterIndex, int SqlType)). Nevertheless,
it requires
an array to contain the information that will be passed to the driver and DBMS. The first
element in this array is the value to be set, which is null, and the
second element is the int supplied for sqlType, which
indicates the type of SQL value that is being set to null. This information
is needed by some DBMSs and is therefore required in order to ensure that applications
are portable.
The other version is intended to be used when the value to be set to null
is a user-defined type. It takes three parameters
(setNull(int parameterIndex, int sqlType, String typeName)) and also
requires an array to contain the information to be passed to the driver and DBMS.
The first two elements in this array are the same as for the first version of
setNull. The third element, typeName, gives the SQL name of
the user-defined type. As is true with the other setter methods, the number of the
placeholder parameter to be set is indicated by an element's position in the array
returned by getParams. So, for example, if the parameter
supplied to setNull is 2, the second element in the array
returned by getParams will be an array of two or three elements.
setObject and setDate have versions
that take more than two parameters, with the extra parameters giving information
to the driver or the DBMS. For example, the methods setDate,
setTime, and setTimestamp can take a Calendar
object as their third parameter. If the DBMS does not store time zone information,
the drivern uses the Calendar object to construct the Date,
Time, or Timestamp object being set. As is true with other
methods that provide additional information, the element in the array returned
by getParams is an array instead of a simple Object instance.
setAsciiStream, setBinaryStream,
setCharacterStream, and setUnicodeStream (which is
deprecated, so applications should use getCharacterStream instead)
take three parameters, so for them, the element in the array returned by
getParams is also an array. What is different about these setter
methods is that in addition to the information provided by parameters, the array contains
one of the BaseRowSet constants indicating the type of stream being set.
getParams is called internally by
RowSet implementations extending this class; it is not normally called by an
application programmer directly.
5.0 Event Notification
The BaseRowSet class provides the event notification
mechanism for rowsets. It contains the field
listeners, methods for adding and removing listeners, and
methods for notifying listeners of changes.
RowSetListener interface.
If it has been added to a RowSet object's list of listeners, it will be notified
when an event occurs on that RowSet object. Each listener's
implementation of the RowSetListener methods defines what that object
will do when it is notified that an event has occurred.
RowSet object:
RowSet object are changed
BaseRowSet method used for the notification indicates the
type of event that has occurred. For example, the method
notifyRowChanged indicates that a row has been updated,
deleted, or inserted. Each of the notification methods creates a
RowSetEvent object, which is supplied to the listener in order to
identify the RowSet object on which the event occurred.
What the listener does with this information, which may be nothing, depends on how it was
implemented.
6.0 Default Behavior
A default BaseRowSet object is initialized with many starting values.
The following is true of a default RowSet instance that extends
the BaseRowSet class:
RowSet object's command.
BINARY, VARBINARY,
LONGVARBINARY, CHAR, VARCHAR,
and LONGVARCHAR.
null.
Vector object for storing the values set
for the placeholder parameters in the RowSet object's command.
CachedRowSet object crs to 500.
crs.setMaxRows(500);
Methods implemented in extensions of this BaseRowSet class must throw an
SQLException object for any violation of the defined assertions. Also, if the
extending class overrides and reimplements any BaseRowSet method and encounters
connectivity or underlying data source issues, that method may in addition throw an
SQLException object for that reason.

The driver will use either the URL property or the
dataSourceName property to create a connection, whichever was
specified most recently. If an application uses a JDBC URL, it
must load a JDBC driver that accepts the JDBC URL before it uses the
RowSet object to connect to a database. The RowSet
object will use the URL internally to create a database connection in order
to read or write data.

public Object[] getParams()
throws SQLException
RowSet object's command and throws an SQLException object
if all parameters have not been set. Before the command is sent to the
DBMS to be executed, these parameters will be substituted
for placeholder parameters in the PreparedStatement object
that is the command for a RowSet implementation extending
the BaseRowSet class.
Object instance
that contains the values of the parameters supplied to a setter method.
The order of the elements is determined by the value supplied for
parameterIndex. If the setter method takes only the parameter index
and the value to be set (possibly null), the array element will contain the value to be set
(which will be expressed as an Object). If there are additional
parameters, the array element will itself be an array containing the value to be set
plus any additional parameter values supplied to the setter method. If the method
sets a stream, the array element includes the type of stream being supplied to the
method. These additional parameters are for the use of the driver or the DBMS and may or
may not be used.
Array, Blob,
Clob and Ref are returned as SerialArray,
SerialBlob, SerialClob and SerialRef
respectively.
Object instances that includes the
parameter values that may be set in this RowSet object's
command; an empty array if no parameters have been set
SQLException - if an error occurs retrieveing the object array of
parameters of this RowSet object or if not all parameters have
been set
