+/**
+ * An interface to an Object which represents a Table of Data, typically
+ * returned as the result of a Query to a Database.
+ * <p>
+ * <code>ResultSets</code> have a Cursor which points to a current row of
+ * data. When a ResultSet is created, the Cursor is positioned before the first
+ * row. To move the Cursor to the next row in the table, use the
+ * <code>next</code> method. The next method returns true until there are no
+ * more rows in the ResultSet, when it returns false.
+ * <p>
+ * The default type of ResultSet cannot be updated and its cursor can only move
+ * forward through the rows of data. This means that it is only possible to read
+ * through it once. However, it is possible to create types of ResultSet that
+ * can be updated and also types where the cursor can be scrolled forward and
+ * backward through the rows of data. This is shown in the following code
+ * example: <code>
+ * 		Connection con;
+ * 		Statement aStatement = con.createStatement( ResultSet.TYPE_SCROLL_SENSITIVE,
+ * 													  ResultSet.CONCUR_UPDATABLE );
+ * 		ResultSet theResultSet = theStatement.executeQuery("SELECT price, quantity FROM STOCKTABLE");
+ * 		// theResultSet will be both scrollable and updateable
+ * </code>
+ * <p>
+ * The ResultSet interface provides a series of methods for retrieving data from
+ * columns in the current row, such as getDate, getFloat. The columns are
+ * identified either by their index number (starting at 1) or by their name -
+ * there are separate methods for both techniques of column addressing. The
+ * column names are case insensitive. If several columns have the same name,
+ * then the getter methods use the first matching column. This means that if
+ * column names are used, it is not possible to guarantee that the name will
+ * retrieve data from the intended column - for certainty it is better to use
+ * column indexes. Ideally the columns should be read left-to-right and read
+ * once only, since not all * databases are optimised to handle other techniques
+ * of reading the data.
+ * <p>
+ * When reading data, the JDBC driver maps the SQL data retrieved from the
+ * database to the Java type implied by the method invoked by the application.
+ * The JDBC specification has a table of allowable mappings from SQL types to
+ * Java types.
+ * <p>
+ * There are also methods for writing data into the ResultSet, such as
+ * updateInt, updateString. The update methods can be used either to modify the
+ * data of an existing row or to insert new data rows into the ResultSet.
+ * Modification of existing data involves moving the Cursor to the row which
+ * needs modification and then using the update methods to modify the data,
+ * followed by calling the ResultSet.updateRow method. For insertion of new
+ * rows, the cursor is first moved to a special row called the Insert Row, data
+ * is added using the update methods, followed by calling the
+ * ResultSet.insertRow method.
+ * <p>
+ * A ResultSet is closed if the Statement object which generated it closed,
+ * executed again or is used to retrieve the next result from a sequence of
+ * results.

+ * <p>
+ * Usually within an implementation of SQLData, there is a corresponding field
+ * for every attribute of an SQL type, or only one field if the type is SQL
+ * DISTINCT. When the UDT is returned within a ResultSet, it is accessed with

+ * this object just like any other Java object and can store changes back into
+ * the database using the PreparedStatement.setObject method which performs the
+ * reverse mapping into the SQL UDT.
+ * <p>
+ * It is standard for an implementation for a custom mapping to be generated by
+ * a tool. The tool usually requires the name of the SQL UDT, the name of the
+ * class which it is going to be mapped to, and the field names to which the UDT
+ * attributes will be mapped. The tool can then implement the SQLData readSQL
+ * and writeSQL methods. readSQL reads attributes from an SQLInput object, and
+ * writeSQL writes them. This is done via SQLInput and SQLOutput method calls
