<p>
<a class="link" href="GDataBatchOperation.html" title="GDataBatchOperation"><span class="type">GDataBatchOperation</span></a> is a transient standalone class which represents and handles a single batch operation request to a service. To make a batch
operation request: create a new <a class="link" href="GDataBatchOperation.html" title="GDataBatchOperation"><span class="type">GDataBatchOperation</span></a>; add the required queries, insertions, updates and deletions to the operation using
<a class="link" href="GDataBatchOperation.html#gdata-batch-operation-add-query" title="gdata_batch_operation_add_query ()"><code class="function">gdata_batch_operation_add_query()</code></a>, <a class="link" href="GDataBatchOperation.html#gdata-batch-operation-add-insertion" title="gdata_batch_operation_add_insertion ()"><code class="function">gdata_batch_operation_add_insertion()</code></a>, <a class="link" href="GDataBatchOperation.html#gdata-batch-operation-add-update" title="gdata_batch_operation_add_update ()"><code class="function">gdata_batch_operation_add_update()</code></a> and
<a class="link" href="GDataBatchOperation.html#gdata-batch-operation-add-deletion" title="gdata_batch_operation_add_deletion ()"><code class="function">gdata_batch_operation_add_deletion()</code></a>, respectively; run the request with <a class="link" href="GDataBatchOperation.html#gdata-batch-operation-run" title="gdata_batch_operation_run ()"><code class="function">gdata_batch_operation_run()</code></a> or <a class="link" href="GDataBatchOperation.html#gdata-batch-operation-run-async" title="gdata_batch_operation_run_async ()"><code class="function">gdata_batch_operation_run_async()</code></a>; and
handle the results in the callback functions which are invoked by the operation as the results are received and parsed.

<p>
If authorization is required for any of the requests in the batch operation, the <a class="link" href="GDataService.html" title="GDataService"><span class="type">GDataService</span></a> set in <a class="link" href="GDataBatchOperation.html#GDataBatchOperation--service" title='The "service" property'><span class="type">"service"</span></a> must have

in <a class="link" href="GDataBatchOperation.html#GDataBatchOperation--authorization-domain" title='The "authorization-domain" property'><span class="type">"authorization-domain"</span></a>. It's not possible for requests in a single batch operation to be authorized under multiple domains;
in that case, the requests must be split up across several batch operations using different authorization domains.
</p>
<p>
If all of the requests in the batch operation don't require authorization (i.e. they all operate on public data; see the documentation for the
<a class="link" href="GDataService.html" title="GDataService"><span class="type">GDataService</span></a> subclass in question's operations for details of which require authorization), <a class="link" href="GDataBatchOperation.html#GDataBatchOperation--authorization-domain" title='The "authorization-domain" property'><span class="type">"authorization-domain"</span></a> can be set
to <a href="/opt/gnome3/build/share/gtk-doc/html/glib/glib-Standard-Macros.html#NULL:CAPS"><code class="literal">NULL</code></a> to save the overhead of sending authorization data to the online service.

If the callback code needs to retain a copy of <em class="parameter"><code>entry</code></em>, it must be referenced (with <a href="/opt/gnome3/build/share/gtk-doc/html/gobject/gobject-The-Base-Object-Type.html#g-object-ref"><code class="function">g_object_ref()</code></a>).

The callback is called in the main thread, and there is no guarantee on the order in which the callbacks for the operations in a run are executed,

Run the <a class="link" href="GDataBatchOperation.html" title="GDataBatchOperation"><span class="type">GDataBatchOperation</span></a> synchronously. This will send all the operations in the batch operation to the server, and call their respective

The callbacks for all of the operations in the batch operation are always guaranteed to be called, even if the batch operation as a whole fails.
