Example 40 with XMLEvent

use of javax.xml.stream.events.XMLEvent in project aalto-xml by FasterXML.

the class TestLaziness method testEventReaderNonLaziness.

 * This test verifies that lazy parsing is not enabled, by making
 * use of a specific side effect of lazy parsing. Specifically, parts
 * of Stax API do not expose XMLStreamException: such as getText()
 * method of the stream reader. Thus we can infer whether lazy mode
 * is enabled or not by whether we get a regular XMLStreamException
 * when trying to access the event, or not.
 *<p>
 * Note: whether this test reliably detecs "laziness" may depend
 * on the event reader implementation.
