Class ResourceListRowData

  • All Implemented Interfaces:
    java.io.Serializable

    public class ResourceListRowData
extends RowData
implements java.io.Serializable
    The ResourceListRowData class represents a resource list of data.

    The list of data is formatted into a series of rows where each row contains a finite number of columns determined by the number of column attribute ID's. Each column within a row contains an individual data item.

    A ResourceListRowData object can represent any implementation of the ResourceList interface. The row data columns are specified as an array of column attribute IDs. The row data will contain a column for each element of the array. The following can be specified as column attribute IDs:

    • null - The name from each Resource's Presentation object are presented in the column.
    • Resource attribute IDs - These are defined by the Resource objects that make up the rows data. The corresponding attribute value is presented in the column.

    A ResourceListRowData object maintains a position in the resource list that points to its current row of data. The initial position in the list is set before the first row. The next method moves to the next row in the list.

    The getObject method is used to retrieve the column value for the current row indexed by the column number. Columns are numbered starting from 0.

    The following example creates a ResourceListRowData object using an RUserList: 

      // Create an object to represent the system.
  AS400 mySystem = new AS400("mySystem.myCompany.com");
  
  // Create a resource user list.
  RUserList userList = new RUserList(sys);
  
  // Set the selection so that all user profiles
  // are included in the list.
  userList.setSelectionValue(RUserList.SELECTION_CRITERIA, RUserList.ALL);
  
  // Create an HTMLTableConverter object.
  HTMLTableConverter converter = new HTMLTableConverter();
  
  // Set up the table tag with a maximum of 20 rows per table.
  converter.setMaximumTableSize(20);
  
  // Create an HTMLTable and use the meta data for the table headers.
  HTMLTable table = new HTMLTable();
  table.setCellSpacing(6);
  table.setBorderWidth(8);
  converter.setTable(table);
  converter.setUseMetaData(true);
  
  // Create a ResourceListRowData.
  ResourceListRowData rowdata = new ResourceListRowData(userList, new Object[] { null, RUser.TEXT_DESCRIPTION } );
 
  // Convert the ResourceListRowData into an HTMLTable.
  String[] html = converter.convert(rowdata);
 
  // Print out the first table of 20 users from the html array.
  System.out.println(html[0]);
