Examples of javax.xml.parsers.DocumentBuilder.reset()

javax.xml.parsers.DocumentBuilder.reset()

Reset this DocumentBuilder to its original configuration.

DocumentBuilder is reset to the same state as when it was created with {@link DocumentBuilderFactory#newDocumentBuilder()}. reset() is designed to allow the reuse of existing DocumentBuilders thus saving resources associated with the creation of new DocumentBuilders.

The reset DocumentBuilder is not guaranteed to have the same {@link EntityResolver} or {@link ErrorHandler}Objects, e.g. {@link Object#equals(Object obj)}. It is guaranteed to have a functionally equal EntityResolver and ErrorHandler.
