<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>
<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="../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.</p>
