+/**
+ * A table of data representing a database result set, which
+ * is usually generated by executing a statement that queries the database.
+ *
+ * <P>A <code>ResultSet</code> object maintains a cursor pointing
+ * to its current row of data. Initially the cursor is positioned
+ * before the first row. The <code>next</code> method moves the
+ * cursor to the next row, and because it returns <code>false</code>
+ * when there are no more rows in the <code>ResultSet</code> object,
+ * it can be used in a <code>while</code> loop to iterate through
+ * the result set.
+ * <P>
+ * A default <code>ResultSet</code> object is not updatable and
+ * has a cursor that moves forward only. Thus, you can
+ * iterate through it only once and only from the first row to the
+ * last row. It is possible to
+ * produce <code>ResultSet</code> objects that are scrollable and/or
+ * updatable. The following code fragment, in which <code>con</code>
+ * is a valid <code>Connection</code> object, illustrates how to make
+ * a result set that is scrollable and insensitive to updates by others, and
+ * that is updatable. See <code>ResultSet</code> fields for other
+ * options.
+ * <PRE>
+ *
+ * Statement stmt = con.createStatement(
+ * ResultSet.TYPE_SCROLL_INSENSITIVE,
+ * ResultSet.CONCUR_UPDATABLE);
+ * ResultSet rs = stmt.executeQuery("SELECT a, b FROM TABLE2");
+ * // rs will be scrollable, will not show changes made by others,
+ * // and will be updatable
+ *
+ * </PRE>
+ * The <code>ResultSet</code> interface provides
+ * <i>getter</i> methods (<code>getBoolean</code>, <code>getLong</code>, and so on)
+ * for retrieving column values from the current row.
+ * Values can be retrieved using either the index number of the
+ * column or the name of the column. In general, using the
+ * column index will be more efficient. Columns are numbered from 1.
+ * For maximum portability, result set columns within each row should be
+ * read in left-to-right order, and each column should be read only once.
+ *
+ * <P>For the getter methods, a JDBC driver attempts
+ * to convert the underlying data to the Java type specified in the
+ * getter method and returns a suitable Java value. The JDBC specification
+ * has a table showing the allowable mappings from SQL types to Java types
+ * that can be used by the <code>ResultSet</code> getter methods.
+ *
+ * <P>Column names used as input to getter methods are case
+ * insensitive. When a getter method is called with
+ * a column name and several columns have the same name,
+ * the value of the first matching column will be returned.
+ * The column name option is
+ * designed to be used when column names are used in the SQL
+ * query that generated the result set.
+ * For columns that are NOT explicitly named in the query, it
+ * is best to use column numbers. If column names are used, the
+ * programmer should take care to guarantee that they uniquely refer to
+ * the intended columns, which can be assured with the SQL <i>AS</i> clause.
+ * <P>
+ * A set of updater methods were added to this interface
+ * in the JDBC 2.0 API (Java™ 2 SDK,
+ * Standard Edition, version 1.2). The comments regarding parameters
+ * to the getter methods also apply to parameters to the
+ * updater methods.
+ *<P>
+ * The updater methods may be used in two ways:
+ * <ol>
+ * <LI>to update a column value in the current row. In a scrollable
+ * <code>ResultSet</code> object, the cursor can be moved backwards
+ * and forwards, to an absolute position, or to a position
+ * relative to the current row.
+ * The following code fragment updates the <code>NAME</code> column
+ * in the fifth row of the <code>ResultSet</code> object
+ * <code>rs</code> and then uses the method <code>updateRow</code>
+ * to update the data source table from which <code>rs</code> was derived.
+ * <PRE>
+ *
+ * rs.absolute(5); // moves the cursor to the fifth row of rs
+ * rs.updateString("NAME", "AINSWORTH"); // updates the
+ * // <code>NAME</code> column of row 5 to be <code>AINSWORTH</code>
+ * rs.updateRow(); // updates the row in the data source
+ *
+ * </PRE>
+ * <LI>to insert column values into the insert row. An updatable
+ * <code>ResultSet</code> object has a special row associated with
+ * it that serves as a staging area for building a row to be inserted.
+ * The following code fragment moves the cursor to the insert row, builds
+ * a three-column row, and inserts it into <code>rs</code> and into
+ * the data source table using the method <code>insertRow</code>.
+ * <PRE>
+ *
+ * rs.moveToInsertRow(); // moves cursor to the insert row
+ * rs.updateString(1, "AINSWORTH"); // updates the
+ * // first column of the insert row to be <code>AINSWORTH</code>
+ * rs.updateInt(2,35); // updates the second column to be <code>35</code>
+ * rs.updateBoolean(3, true); // updates the third column to <code>true</code>
+ * rs.insertRow();
+ * rs.moveToCurrentRow();
+ *
+ * </PRE>
+ * </ol>
+ * <P>A <code>ResultSet</code> object is automatically closed when the
+ * <code>Statement</code> object that
+ * generated it is closed, re-executed, or used
+ * to retrieve the next result from a sequence of multiple results.
+ *
+ * <P>The number, types and properties of a <code>ResultSet</code>
+ * object's columns are provided by the <code>ResultSetMetaData</code>
+ * object returned by the <code>ResultSet.getMetaData</code> method.
+ *
+ * @see Statement#executeQuery
+ * @see Statement#getResultSet
+ * @see ResultSetMetaData
+ * @since 1.1
