Handling direct downloads

To handle direct downloads, complete the following steps:

To handle direct downloads
  1. Register a Java or .NET method for the handle_DownloadData connection event.

  2. Write a method for the handle_DownloadData synchronization event. In this event you use an instance of DBConnectionContext to get a DowloadData instance for the current synchronization. See:

You can create the entire direct download in the handle_DownloadData synchronization event. Alternatively, you can use other synchronization events to set direct download operations. However, you must create a handle_DownloadData script, even if its method does nothing. If you process the direct download in an event other than handle_DownloadData, the event cannot be before begin_synchronization and cannot be after end_download.

For information about the order of events, see MobiLink complete event model.

Classes for direct downloads

The MobiLink server APIs for Java and .NET provide the following classes for creating direct downloads:

  • DownloadData   Encapsulates download tables containing operations to send down to a remote client during synchronization. See:

  • DownloadTableData   Encapsulates upsert (update and insert) and delete operations to download to a MobiLink client.

    For Java, DownloadTableData methods return an instance of a JDBC PreparedStatement. In Java, you add a row to the download by setting the prepared statement's column values and then executing the prepared statement.

    For .NET, DownloadTableData methods return an instance of a .NET IDbCommand. In .NET, you add a row to the download by setting the command's column values and then executing the command.
