<!-- ==================== CLASS DESCRIPTION ==================== -->
<h1 class="epydoc">Class DOIQuery</h1><span class="codelink"><a href="Pyblio.External.CrossRef-pysrc.html#DOIQuery">source&nbsp;code</a></span><br /><br />
<pre class="base-tree">
object --+
|
<strong class="uidshort">DOIQuery</strong>
</pre>
<hr />
<p>Query DOI numbers.</p>
Convenience module that properly groups queries to CrossRef in order
to increase throughput.
<pre class="py-doctest">
<span class="py-prompt">&gt;&gt;&gt; </span>cnx = DOIQuery(db, user=..., pwd=...)
<span class="py-prompt">&gt;&gt;&gt; </span><span class="py-keyword">for</span> info <span class="py-keyword">in</span> to_resolve:
<span class="py-more">... </span> cnx.journalSearch(...).addCallback(got_results)
<span class="py-prompt">&gt;&gt;&gt; </span>cnx.finished()</pre>
<p>The 'db' parameter is a database from which the queries and results
will be composed. It must conform to the
<i>org.pybliographer/crossref/0.1</i> schema.</p>
<p>The actual queries take place when enough searches have been
requested, or when the .finished() method is called.</p>
<p>For each query, a list of possible DOIs is returned. It can possibly
be empty if the citation could not be resolved.</p>
In case of a failure in the query protocol itself, the registered
errback handlers are called for each query.<br /><br />
