Example: Using ListRowData

This example has three parts:

• Java source that shows how the ListRowData class works
• HTML source generated from the Java source by the using HTMLTableConverter
• How a browser displays the generated HTML

Java™ source that shows how the ListRowData class works

     // Access an existing non-empty data queue
     KeyedDataQueue dq = new KeyedDataQueue(systemObject_, "/QSYS.LIB/MYLIB.LIB/MYDQ.DTAQ");

     // Create a metadata object.
     ListMetaData metaData = new ListMetaData(2);

     // Set first column to be the customer ID.
     metaData.setColumnName(0, "Customer ID");
     metaData.setColumnLabel(0, "Customer ID");
     metaData.setColumnType(0, RowMetaDataType.STRING_DATA_TYPE);

     // Set second column to be the order to be processed.
     metaData.setColumnName(1, "Order Number");
     metaData.setColumnLabel(1, "Order Number");
     metaData.setColumnType(1, RowMetaDataType.STRING_DATA_TYPE);

     // Create a ListRowData object.
     ListRowData rowData = new ListRowData();
     rowData.setMetaData(metaData);

     // Get the entries off the data queue.
     KeyedDataQueueEntry data = dq.read(key, 0, "EQ");
     while (data != null)
     {
        // Add queue entry to row data object.
        Object[] row = new Object[2];
        row[0] = new String(key);
        row[1] = new String(data.getData());
        rowData.addRow(row);

        // Get another entry from the queue.
        data = dq.read(key, 0, "EQ");
     }

     // Create an HTML converter object and convert the rowData to HTML.
     HTMLTableConverter conv = new HTMLTableConverter();
     conv.setUseMetaData(true);
     HTMLTable[] html = conv.convertToTables(rowData);

     // Display the output from the converter.
     System.out.println(html[0]);

HTML source generated from the Java source by the using HTMLTableConverter

Using the HTMLTableConverter class in the Java source example above generates the following HTML code.

     <table>
     <tr>
     <th>Customer ID</th>
     <th>Order Number</th>
     </tr>
     <tr>
     <td>777-53-4444</td>
     <td>12345-XYZ</td>
     </tr>
     <tr>
     <td>777-53-4444</td>
     <td>56789-ABC</td>
     </tr>
     </table>

How a browser displays the generated HTML

The following table shows how the HTML source code looks when viewed in a browser.
