/**
* An abstract class providing a <code>RowSet</code> object with its basic functionality.
* The basic functions include having properties and sending event notifications,
* which all JavaBeans™ components must implement.
*
* <h3>1.0 Overview</h3>
* The <code>BaseRowSet</code> class provides the core functionality
* for all <code>RowSet</code> implementations,
* and all standard implementations <b>may</b> use this class in combination with
* one or more <code>RowSet</code> interfaces in order to provide a standard
* vendor-specific implementation. To clarify, all implementations must implement
* at least one of the <code>RowSet</code> interfaces (<code>JdbcRowSet</code>,
* <code>CachedRowSet</code>, <code>JoinRowSet</code>, <code>FilteredRowSet</code>,
* or <code>WebRowSet</code>). This means that any implementation that extends
* the <code>BaseRowSet</code> class must also implement one of the <code>RowSet</code>
* interfaces.
* <p>
* The <code>BaseRowSet</code> class provides the following:
*
* <UL>
* <LI><b>Properties</b>
* <ul>
* <li>Fields for storing current properties
* <li>Methods for getting and setting properties
* </ul>
*
* <LI><b>Event notification</b>
*
* <LI><b>A complete set of setter methods</b> for setting the parameters in a
* <code>RowSet</code> object's command
*
* <LI> <b>Streams</b>
* <ul>
* <li>Fields for storing stream instances
* <li>Constants for indicating the type of a stream
* </ul>
* </UL>
*
* <h3>2.0 Setting Properties</h3>
* 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 the <code>RowSet</code> implementation does and how it gets
* its data. For example,
* rowsets that get their data from a <code>ResultSet</code> object need to
* set the properties that are required for making a database connection.
* If a <code>RowSet</code> object uses the <code>DriverManager</code> 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 <code>DataSource</code> 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.
* <P>
* NOTE: In order to use a <code>DataSource</code> object for making a
* connection, the <code>DataSource</code> object must have been registered
* with a naming service that uses the Java Naming and Directory
* Interface™ (JNDI) API. This registration
* is usually done by a person acting in the capacity of a system administrator.
*
* <h3>3.0 Setting the Command and Its Parameters</h3>
* When a rowset gets its data from a relational database, it executes a command (a query)
* that produces a <code>ResultSet</code> object. This query is the command that is set
* for the <code>RowSet</code> object's command property. The rowset populates itself with data by reading the
* data from the <code>ResultSet</code> object into itself. If the query
* contains placeholders for values to be set, the <code>BaseRowSet</code> setter methods
* are used to set these values. All setter methods allow these values to be set
* to <code>null</code> if required.
* <P>
* The following code fragment illustrates how the
* <code>CachedRowSet</code>™
* object <code>crs</code> 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.
* <PRE>{@code
* crs.setCommand("SELECT FIRST_NAME, LAST_NAME, ADDRESS FROM CUSTOMERS" +
* "WHERE CREDIT_LIMIT > ? AND REGION = ?");
* }</PRE>
* <P>
* In this example, the values for <code>CREDIT_LIMIT</code> and
* <code>REGION</code> are placeholder parameters, which are indicated with a
* question mark (?). The first question mark is placeholder parameter number
* <code>1</code>, the second question mark is placeholder parameter number
* <code>2</code>, and so on. Any placeholder parameters must be set with
* values before the query can be executed. To set these
* placeholder parameters, the <code>BaseRowSet</code> class provides a set of setter
* methods, similar to those provided by the <code>PreparedStatement</code>
* interface, for setting values of each data type. A <code>RowSet</code> object stores the
* parameter values internally, and its <code>execute</code> method uses them internally
* to set values for the placeholder parameters
* before it sends the command to the DBMS to be executed.
* <P>
* The following code fragment demonstrates
* setting the two parameters in the query from the previous example.
* <PRE>{@code
* crs.setInt(1, 5000);
* crs.setString(2, "West");
* }</PRE>
* If the <code>execute</code> method is called at this point, the query
* sent to the DBMS will be:
* <PRE>{@code
* "SELECT FIRST_NAME, LAST_NAME, ADDRESS FROM CUSTOMERS" +
* "WHERE CREDIT_LIMIT > 5000 AND REGION = 'West'"
* }</PRE>
* NOTE: Setting <code>Array</code>, <code>Clob</code>, <code>Blob</code> and
* <code>Ref</code> objects as a command parameter, stores these values as
* <code>SerialArray</code>, <code>SerialClob</code>, <code>SerialBlob</code>
* and <code>SerialRef</code> objects respectively.
*
* <h3>4.0 Handling of Parameters Behind the Scenes</h3>
*
* NOTE: The <code>BaseRowSet</code> 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.
* <P>
* The placeholder parameters set with the <code>BaseRowSet</code> setter methods
* are stored as objects in an internal <code>Hashtable</code> object.
* Primitives are stored as their <code>Object</code> type. For example, <code>byte</code>
* is stored as <code>Byte</code> object, and <code>int</code> is stored as
* an <code>Integer</code> object.
* When the method <code>execute</code> is called, the values in the
* <code>Hashtable</code> object are substituted for the appropriate placeholder
* parameters in the command.
* <P>
* A call to the method <code>getParams</code> returns the values stored in the
* <code>Hashtable</code> object as an array of <code>Object</code> instances.
* An element in this array may be a simple <code>Object</code> instance or an
* array (which is a type of <code>Object</code>). The particular setter method used
* determines whether an element in this array is an <code>Object</code> or an array.
* <P>
* 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 <code>setInt</code>,
* <code>setString</code>, <code>setBoolean</code>, and <code>setLong</code> fall into
* this category. After these methods have been called, a call to the method
* <code>getParams</code> will return an array with the values that have been set. Each
* element in the array is an <code>Object</code> instance representing the
* values that have been set. The order of these values in the array is determined by the
* <code>int</code> (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 <code>RowSet</code> object's
* command. The second element is the value to
* be set for the second placeholder parameter, and so on.
* <P>
* Several setter methods send the driver and DBMS information beyond the value to be set.
* When the method <code>getParams</code> 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 <code>setNull</code> is a special case
* because one version takes only
* two parameters (<code>setNull(int parameterIndex, int SqlType)</code>). 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 <code>null</code>, and the
* second element is the <code>int</code> supplied for <i>sqlType</i>, which
* indicates the type of SQL value that is being set to <code>null</code>. 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 <code>null</code>
* is a user-defined type. It takes three parameters
* (<code>setNull(int parameterIndex, int sqlType, String typeName)</code>) 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
* <code>setNull</code>. The third element, <i>typeName</i>, 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 <code>getParams</code>. So, for example, if the parameter
* supplied to <code>setNull</code> is <code>2</code>, the second element in the array
* returned by <code>getParams</code> will be an array of two or three elements.
* <P>
* Some methods, such as <code>setObject</code> and <code>setDate</code> have versions
* that take more than two parameters, with the extra parameters giving information
* to the driver or the DBMS. For example, the methods <code>setDate</code>,
* <code>setTime</code>, and <code>setTimestamp</code> can take a <code>Calendar</code>
* object as their third parameter. If the DBMS does not store time zone information,
* the driver uses the <code>Calendar</code> object to construct the <code>Date</code>,
* <code>Time</code>, or <code>Timestamp</code> object being set. As is true with other
* methods that provide additional information, the element in the array returned
* by <code>getParams</code> is an array instead of a simple <code>Object</code> instance.
* <P>
* The methods <code>setAsciiStream</code>, <code>setBinaryStream</code>,
* <code>setCharacterStream</code>, and <code>setUnicodeStream</code> (which is
* deprecated, so applications should use <code>getCharacterStream</code> instead)
* take three parameters, so for them, the element in the array returned by
* <code>getParams</code> 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 <code>BaseRowSet</code> constants indicating the type of stream being set.
* <p>
* NOTE: The method <code>getParams</code> is called internally by
* <code>RowSet</code> implementations extending this class; it is not normally called by an
* application programmer directly.
*
* <h3>5.0 Event Notification</h3>
* The <code>BaseRowSet</code> class provides the event notification
* mechanism for rowsets. It contains the field
* <code>listeners</code>, methods for adding and removing listeners, and
* methods for notifying listeners of changes.
* <P>
* A listener is an object that has implemented the <code>RowSetListener</code> interface.
* If it has been added to a <code>RowSet</code> object's list of listeners, it will be notified
* when an event occurs on that <code>RowSet</code> object. Each listener's
* implementation of the <code>RowSetListener</code> methods defines what that object
* will do when it is notified that an event has occurred.
* <P>
* There are three possible events for a <code>RowSet</code> object:
* <OL>
* <LI>the cursor moves
* <LI>an individual row is changed (updated, deleted, or inserted)
* <LI>the contents of the entire <code>RowSet</code> object are changed
* </OL>
* <P>
* The <code>BaseRowSet</code> method used for the notification indicates the
* type of event that has occurred. For example, the method
* <code>notifyRowChanged</code> indicates that a row has been updated,
* deleted, or inserted. Each of the notification methods creates a
* <code>RowSetEvent</code> object, which is supplied to the listener in order to
* identify the <code>RowSet</code> object on which the event occurred.
* What the listener does with this information, which may be nothing, depends on how it was
* implemented.
*
* <h3>6.0 Default Behavior</h3>
* A default <code>BaseRowSet</code> object is initialized with many starting values.
*
* The following is true of a default <code>RowSet</code> instance that extends
* the <code>BaseRowSet</code> class:
* <UL>
* <LI>Has a scrollable cursor and does not show changes
* made by others.
* <LI>Is updatable.
* <LI>Does not show rows that have been deleted.
* <LI>Has no time limit for how long a driver may take to
* execute the <code>RowSet</code> object's command.
* <LI>Has no limit for the number of rows it may contain.
* <LI>Has no limit for the number of bytes a column may contain. NOTE: This
* limit applies only to columns that hold values of the
* following types: <code>BINARY</code>, <code>VARBINARY</code>,
* <code>LONGVARBINARY</code>, <code>CHAR</code>, <code>VARCHAR</code>,
* and <code>LONGVARCHAR</code>.
* <LI>Will not see uncommitted data (make "dirty" reads).
* <LI>Has escape processing turned on.
* <LI>Has its connection's type map set to <code>null</code>.
* <LI>Has an empty <code>Vector</code> object for storing the values set
* for the placeholder parameters in the <code>RowSet</code> object's command.
* </UL>
* <p>
* If other values are desired, an application must set the property values
* explicitly. For example, the following line of code sets the maximum number
* of rows for the <code>CachedRowSet</code> object <i>crs</i> to 500.
* <PRE>
* crs.setMaxRows(500);
* </PRE>
* Methods implemented in extensions of this <code>BaseRowSet</code> class <b>must</b> throw an
* <code>SQLException</code> object for any violation of the defined assertions. Also, if the
* extending class overrides and reimplements any <code>BaseRowSet</code> method and encounters
* connectivity or underlying data source issues, that method <b>may</b> in addition throw an
* <code>SQLException</code> object for that reason.
