Sync custom items: Implement the methods of the ISiteSyncSnapIn interface

You implement the following methods:

• GetPendingItems
  The GetPendingItems method returns the items that are pending for synchronization for the current type.

  To implement the method, use the following code sample:

• GetExportItemsCount
  The GetExportItemsCount is a method that you implement for your custom snap-in. It gives you the number of the items that you have checked for export.
  Inside this method, you call GetExportItems, which gets only the items that you have checked for syncing.

  Use the following code sample:

• Export
  The Export method is the method that exports the items for syncing. Inside this method, you go through the log entries that are check for synchronization for the current type. For every log entry, you create a WrapperObject that you add to the export transaction. In this object, you can add properties and their values. You can also give an object with properties to the constructor of the Wrapper object. With the CommonItemLoader you can set the common properties for the log entry.

  In the export transaction, you set the header for the current site sync snap-in and in the export transaction items you add the wrapper objects.

  Use the following code sample:

NOTE: You can choose how you want to export the items – all items in one transaction, or a separate transaction for each entry.
