Create a DatastoreFile

The datastore features are all contained within the Autonomy.Connector.Datastore namespace. The samples in this section assume there is a using directive for this namespace at the beginning of the file:

       using Autonomy.Connector.Datastore;

You can access a datastore for the synchronize action like this:

       public override void Synchronize(ISynchronizeTask task)	
       {
           using (DatastoreFile datastore = new DatastoreFile(
			task.DatastoreFileName, task.Log))
           {
               // Use datastore ...
           }		
       }

This opens or creates the datastore in the file named in task.DatastoreFileName. If the datastore already exists the existing datastore is opened (the datastore is not created again). The DatastoreFile object provides access to the datastore. This object is disposable, so enclose it in a using block.

Best Practice

OpenText recommends that you use the file named in ISynchronizeTask.DatastoreFileName to store all state information for the task. You can use the DatastoreFile object to store a datastore in that file, or use a format of your choosing.

The advantages of storing all state information in the file specified by ISynchronizeTask.DatastoreFileName include:

• ConnectorLib .NET chooses a unique file name that does not conflict with the names used for other tasks. The file name also respects configuration settings regarding the datastore location.
• The same file name is provided to other actions called for the same task (collect, view, insert, update, and so on.)
• The file is backed up and restored automatically if the backup and restore actions are used.
