title: HibernateTemplate SaveOrUpdateAll
body: <p>HibernateTemplate class has following method</p>
  
  <pre><code>getHibernateTemplate().saveOrUpdateAll(Collection entities)
  </code></pre>
  
  <p>But why it has not only <code>saveAll()</code> method? like this</p>
  
  <pre><code>getHibernateTemplate().saveAll(Collection entities)
  </code></pre>
  
  <p>what happened if I only want to save collection not to update it?</p>
