37  /**
38   * An abstract class providing a <code>RowSet</code> object with its basic functionality.
39   * The basic functions include having properties and sending event notifications,
40   * which all JavaBeans&trade; components must implement.
41   *
42   * <h3>1.0 Overview</h3>
43   * The <code>BaseRowSet</code> class provides the core functionality
44   * for all <code>RowSet</code> implementations,
45   * and all standard implementations <b>may</b> use this class in combination with
46   * one or more <code>RowSet</code> interfaces in order to provide a standard
47   * vendor-specific implementation.  To clarify, all implementations must implement
48   * at least one of the <code>RowSet</code> interfaces (<code>JdbcRowSet</code>,
49   * <code>CachedRowSet</code>, <code>JoinRowSet</code>, <code>FilteredRowSet</code>,
50   * or <code>WebRowSet</code>). This means that any implementation that extends
51   * the <code>BaseRowSet</code> class must also implement one of the <code>RowSet</code>
52   * interfaces.
53   * <p>
54   * The <code>BaseRowSet</code> class provides the following:
55   *
56   * <UL>
57   * <LI><b>Properties</b>
58   *     <ul>
59   *     <li>Fields for storing current properties
60   *     <li>Methods for getting and setting properties
61   *     </ul>
62   *
63   * <LI><b>Event notification</b>
64   *
65   * <LI><b>A complete set of setter methods</b> for setting the parameters in a
66   *      <code>RowSet</code> object's command
67   *
68   * <LI> <b>Streams</b>
69   *  <ul>
70   *  <li>Fields for storing stream instances
71   *  <li>Constants for indicating the type of a stream
72   *  </ul>
73   *  <p>
74   * </UL>
75   *
76   * <h3>2.0 Setting Properties</h3>
77   * All rowsets maintain a set of properties, which will usually be set using
78   * a tool.  The number and kinds of properties a rowset has will vary,
79   * depending on what the <code>RowSet</code> implementation does and how it gets
80   * its data.  For example,
81   * rowsets that get their data from a <code>ResultSet</code> object need to
82   * set the properties that are required for making a database connection.
83   * If a <code>RowSet</code> object uses the <code>DriverManager</code> facility to make a
84   * connection, it needs to set a property for the JDBC URL that identifies the
85   * appropriate driver, and it needs to set the properties that give the
86   * user name and password.
87   * If, on the other hand, the rowset uses a <code>DataSource</code> object
88   * to make the connection, which is the preferred method, it does not need to
89   * set the property for the JDBC URL.  Instead, it needs to set the property
90   * for the logical name of the data source along with the properties for
91   * the user name and password.
92   * <P>
93   * NOTE:  In order to use a <code>DataSource</code> object for making a
94   * connection, the <code>DataSource</code> object must have been registered
95   * with a naming service that uses the Java Naming and Directory
96   * Interface&trade; (JNDI) API.  This registration
97   * is usually done by a person acting in the capacity of a system administrator.
98   *
99   * <h3>3.0 Setting the Command and Its Parameters</h3>
100  * When a rowset gets its data from a relational database, it executes a command (a query)
101  * that produces a <code>ResultSet</code> object.  This query is the command that is set
102  * for the <code>RowSet</code> object's command property.  The rowset populates itself with data by reading the
103  * data from the <code>ResultSet</code> object into itself. If the query
104  * contains placeholders for values to be set, the <code>BaseRowSet</code> setter methods
105  * are used to set these values. All setter methods allow these values to be set
106  * to <code>null</code> if required.
107  * <P>
108  * The following code fragment illustrates how the
109  * <code>CachedRowSet</code>&trade;
110  * object <code>crs</code> might have its command property set.  Note that if a
111  * tool is used to set properties, this is the code that the tool would use.
112  * <PRE>{@code
113  *    crs.setCommand("SELECT FIRST_NAME, LAST_NAME, ADDRESS FROM CUSTOMERS" +
114  *                   "WHERE CREDIT_LIMIT > ? AND REGION = ?");
115  * }</PRE>
116  * <P>
117  * In this example, the values for <code>CREDIT_LIMIT</code> and
118  * <code>REGION</code> are placeholder parameters, which are indicated with a
119  * question mark (?).  The first question mark is placeholder parameter number
120  * <code>1</code>, the second question mark is placeholder parameter number
121  * <code>2</code>, and so on.  Any placeholder parameters must be set with
122  * values before the query can be executed. To set these
123  * placeholder parameters, the <code>BaseRowSet</code> class provides a set of setter
124  * methods, similar to those provided by the <code>PreparedStatement</code>
125  * interface, for setting values of each data type.  A <code>RowSet</code> object stores the
126  * parameter values internally, and its <code>execute</code> method uses them internally
127  * to set values for the placeholder parameters
128  * before it sends the command to the DBMS to be executed.
129  * <P>
130  * The following code fragment demonstrates
131  * setting the two parameters in the query from the previous example.
132  * <PRE>{@code
133  *    crs.setInt(1, 5000);
134  *    crs.setString(2, "West");
135  * }</PRE>
136  * If the <code>execute</code> method is called at this point, the query
137  * sent to the DBMS will be:
138  * <PRE>{@code
139  *    "SELECT FIRST_NAME, LAST_NAME, ADDRESS FROM CUSTOMERS" +
140  *                   "WHERE CREDIT_LIMIT > 5000 AND REGION = 'West'"
141  * }</PRE>
142  * NOTE: Setting <code>Array</code>, <code>Clob</code>, <code>Blob</code> and
143  * <code>Ref</code> objects as a command parameter, stores these values as
144  * <code>SerialArray</code>, <code>SerialClob</code>, <code>SerialBlob</code>
145  * and <code>SerialRef</code> objects respectively.
146  *
147  * <h3>4.0 Handling of Parameters Behind the Scenes</h3>
148  *
149  * NOTE: The <code>BaseRowSet</code> class provides two kinds of setter methods,
150  * those that set properties and those that set placeholder parameters. The setter
151  * methods discussed in this section are those that set placeholder parameters.
152  * <P>
153  * The placeholder parameters set with the <code>BaseRowSet</code> setter methods
154  * are stored as objects in an internal <code>Hashtable</code> object.
155  * Primitives are stored as their <code>Object</code> type. For example, <code>byte</code>
156  * is stored as <code>Byte</code> object, and <code>int</code> is stored as
157  * an <code>Integer</code> object.
158  * When the method <code>execute</code> is called, the values in the
159  * <code>Hashtable</code> object are substituted for the appropriate placeholder
160  * parameters in the command.
161  * <P>
162  * A call to the method <code>getParams</code> returns the values stored in the
163  * <code>Hashtable</code> object as an array of <code>Object</code> instances.
164  * An element in this array may be a simple <code>Object</code> instance or an
165  * array (which is a type of <code>Object</code>). The particular setter method used
166  * determines whether an element in this array is an <code>Object</code> or an array.
167  * <P>
168  * The majority of methods for setting placeholder parameters take two parameters,
169  *  with the first parameter
170  * indicating which placeholder parameter is to be set, and the second parameter
171  * giving the value to be set.  Methods such as <code>setInt</code>,
172  * <code>setString</code>, <code>setBoolean</code>, and <code>setLong</code> fall into
173  * this category.  After these methods have been called, a call to the method
174  * <code>getParams</code> will return an array with the values that have been set. Each
175  * element in the array is an <code>Object</code> instance representing the
176  * values that have been set. The order of these values in the array is determined by the
177  * <code>int</code> (the first parameter) passed to the setter method. The values in the
178  * array are the values (the second parameter) passed to the setter method.
179  * In other words, the first element in the array is the value
180  * to be set for the first placeholder parameter in the <code>RowSet</code> object's
181  * command. The second element is the value to
182  * be set for the second placeholder parameter, and so on.
183  * <P>
184  * Several setter methods send the driver and DBMS information beyond the value to be set.
185  * When the method <code>getParams</code> is called after one of these setter methods has
186  * been used, the elements in the array will themselves be arrays to accommodate the
187  * additional information. In this category, the method <code>setNull</code> is a special case
188  * because one version takes only
189  * two parameters (<code>setNull(int parameterIndex, int SqlType)</code>). Nevertheless,
190  * it requires
191  * an array to contain the information that will be passed to the driver and DBMS.  The first
192  * element in this array is the value to be set, which is <code>null</code>, and the
193  * second element is the <code>int</code> supplied for <i>sqlType</i>, which
194  * indicates the type of SQL value that is being set to <code>null</code>. This information
195  * is needed by some DBMSs and is therefore required in order to ensure that applications
196  * are portable.
197  * The other version is intended to be used when the value to be set to <code>null</code>
198  * is a user-defined type. It takes three parameters
199  * (<code>setNull(int parameterIndex, int sqlType, String typeName)</code>) and also
200  * requires an array to contain the information to be passed to the driver and DBMS.
201  * The first two elements in this array are the same as for the first version of
202  * <code>setNull</code>.  The third element, <i>typeName</i>, gives the SQL name of
203  * the user-defined type. As is true with the other setter methods, the number of the
204  * placeholder parameter to be set is indicated by an element's position in the array
205  * returned by <code>getParams</code>.  So, for example, if the parameter
206  * supplied to <code>setNull</code> is <code>2</code>, the second element in the array
207  * returned by <code>getParams</code> will be an array of two or three elements.
208  * <P>
209  * Some methods, such as <code>setObject</code> and <code>setDate</code> have versions
210  * that take more than two parameters, with the extra parameters giving information
211  * to the driver or the DBMS. For example, the methods <code>setDate</code>,
212  * <code>setTime</code>, and <code>setTimestamp</code> can take a <code>Calendar</code>
213  * object as their third parameter.  If the DBMS does not store time zone information,
214  * the driver uses the <code>Calendar</code> object to construct the <code>Date</code>,
215  * <code>Time</code>, or <code>Timestamp</code> object being set. As is true with other
216  * methods that provide additional information, the element in the array returned
217  * by <code>getParams</code> is an array instead of a simple <code>Object</code> instance.
218  * <P>
219  * The methods <code>setAsciiStream</code>, <code>setBinaryStream</code>,
220  * <code>setCharacterStream</code>, and <code>setUnicodeStream</code> (which is
221  * deprecated, so applications should use <code>getCharacterStream</code> instead)
222  * take three parameters, so for them, the element in the array returned by
223  * <code>getParams</code> is also an array.  What is different about these setter
224  * methods is that in addition to the information provided by parameters, the array contains
225  * one of the <code>BaseRowSet</code> constants indicating the type of stream being set.
226 * <p>
227 * NOTE: The method <code>getParams</code> is called internally by
228 * <code>RowSet</code> implementations extending this class; it is not normally called by an
229 * application programmer directly.
230 *
231 * <h3>5.0 Event Notification</h3>
232 * The <code>BaseRowSet</code> class provides the event notification
233 * mechanism for rowsets.  It contains the field
234 * <code>listeners</code>, methods for adding and removing listeners, and
235 * methods for notifying listeners of changes.
236 * <P>
237 * A listener is an object that has implemented the <code>RowSetListener</code> interface.
238 * If it has been added to a <code>RowSet</code> object's list of listeners, it will be notified
239 *  when an event occurs on that <code>RowSet</code> object.  Each listener's
240 * implementation of the <code>RowSetListener</code> methods defines what that object
241 * will do when it is notified that an event has occurred.
242 * <P>
243 * There are three possible events for a <code>RowSet</code> object:
244 * <OL>
245 * <LI>the cursor moves
246 * <LI>an individual row is changed (updated, deleted, or inserted)
247 * <LI>the contents of the entire <code>RowSet</code> object  are changed
248 * </OL>
249 * <P>
250 * The <code>BaseRowSet</code> method used for the notification indicates the
251 * type of event that has occurred.  For example, the method
252 * <code>notifyRowChanged</code> indicates that a row has been updated,
253 * deleted, or inserted.  Each of the notification methods creates a
254 * <code>RowSetEvent</code> object, which is supplied to the listener in order to
255 * identify the <code>RowSet</code> object on which the event occurred.
256 * What the listener does with this information, which may be nothing, depends on how it was
257 * implemented.
258 *
259 * <h3>6.0 Default Behavior</h3>
260 * A default <code>BaseRowSet</code> object is initialized with many starting values.
261 *
262 * The following is true of a default <code>RowSet</code> instance that extends
263 * the <code>BaseRowSet</code> class:
264 * <UL>
265 *   <LI>Has a scrollable cursor and does not show changes
266 *       made by others.
267 *   <LI>Is updatable.
268 *   <LI>Does not show rows that have been deleted.
269 *   <LI>Has no time limit for how long a driver may take to
270 *       execute the <code>RowSet</code> object's command.
271 *   <LI>Has no limit for the number of rows it may contain.
272 *   <LI>Has no limit for the number of bytes a column may contain. NOTE: This
273 *   limit applies only to columns that hold values of the
274 *   following types:  <code>BINARY</code>, <code>VARBINARY</code>,
275 *   <code>LONGVARBINARY</code>, <code>CHAR</code>, <code>VARCHAR</code>,
276 *   and <code>LONGVARCHAR</code>.
277 *   <LI>Will not see uncommitted data (make "dirty" reads).
278 *   <LI>Has escape processing turned on.
279 *   <LI>Has its connection's type map set to <code>null</code>.
280 *   <LI>Has an empty <code>Vector</code> object for storing the values set
281 *       for the placeholder parameters in the <code>RowSet</code> object's command.
282 * </UL>
283 * <p>
284 * If other values are desired, an application must set the property values
285 * explicitly. For example, the following line of code sets the maximum number
286 * of rows for the <code>CachedRowSet</code> object <i>crs</i> to 500.
287 * <PRE>
288 *    crs.setMaxRows(500);
289 * </PRE>
290 * Methods implemented in extensions of this <code>BaseRowSet</code> class <b>must</b> throw an
291 * <code>SQLException</code> object for any violation of the defined assertions.  Also, if the
292 * extending class overrides and reimplements any <code>BaseRowSet</code> method and encounters
293 * connectivity or underlying data source issues, that method <b>may</b> in addition throw an
294 * <code>SQLException</code> object for that reason.
