| /** |
| * <p>A sample demonstrating how to use the JAXP 1.4 Validation API |
| * to create a validator and use the validator to validate input |
| * from SAX, DOM, StAX or a stream. The output of this program shows |
| * the time spent executing the Validator.validate(Source) method.</p> |
| * |
| * <p>This class is useful as a "poor-man's" performance tester to |
| * compare the speed of various JAXP 1.4 validators with different |
| * input sources. However, it is important to note that the first |
| * validation time of a validator will include both VM class load time |
| * and validator initialization that would not be present in subsequent |
| * validations with the same document. Also note that when the source for |
| * validation is SAX, StAX or a stream, the validation time will also |
| * include the time to parse the document, whereas the DOM validation is |
| * completely in memory.</p> |
| * |
| * <p><strong>Note:</strong> The results produced by this program |
| * should never be accepted as true performance measurements.</p> |
