How to get store_id when user select any store (or store view) from store switcher from cms(content) page filter option (admin) in Magento 2.1?
<p>I want <code>store_id</code> in <code>vendor/magento/module-cms/Model/RosourceModel/AbstractCollection.php</code> in below method </p>

<pre><code>protected function joinStoreRelationTable($tableName, $linkField)
{
    if ($this-&gt;getFilter('store')) 
    {
          // Here i want store_id ; 
    } 
}
</code></pre>
