<p>This helper class manages event listener subscriptions and event dispatching for <a href="Poco.XML.AbstractNode.html" title="class Poco::XML::AbstractNode">AbstractNode</a>. </p>
<p>The <a href="Poco.XML.EventListener.html" title="class Poco::XML::EventListener">EventListener</a> list is managed in such a way that event listeners can be added and removed even from within an <a href="Poco.XML.EventListener.html" title="class Poco::XML::EventListener">EventListener</a>, while events are being dispatched. </p>
