## Common Development Tasks

### Adding a Protocol Client

1. **Implement `CrawlerClient`**:
```java
public class MyClient extends AbstractCrawlerClient {
    @Override
    public ResponseData execute(RequestData request) { /* ... */ }

    @Override
    public void close() { /* cleanup */ }
}
```

2. **Register in DI config** (`crawler.xml`):
```xml

     * @param outExt the output file extension
     */
    public void addConversionRule(final String inExt, final String outExt) {
        extensionMap.put(inExt, outExt);
    }

    /*
     * (non-Javadoc)
     *
     * @see org.codelibs.fess.crawler.extractor.Extractor#getText(java.io.InputStream,
     * java.util.Map)
     */
    @Override

         * Creates a new XmlSitemapsHandler instance.
         */
        public XmlSitemapsHandler() {
            // Default constructor
        }

        @Override
        public void startDocument() {
            sitemapSet = new SitemapSet();
            sitemapSet.setType(SitemapSet.URLSET);
        }

        @Override

/**
 * {@link SAXParserFactoryUtil}のテストです。
 *
 * @author koichik
 */
public class SAXParserFactoryUtilTest extends TestCase {

    boolean included;

    /**
     * {@link SAXParserFactoryUtil#setXIncludeAware}のテストです。
     *
     * @throws Exception
     */
    public void testSetXIncludeAware() throws Exception {
        final SAXParserFactory spf = SAXParserFactoryUtil.newInstance();
