4. **Add tests**: Unit + integration

### Adding a Content Extractor

1. **Implement `Extractor`**:
```java
public class MyExtractor extends AbstractExtractor {
    @Override
    public ExtractData getText(InputStream in, Map<String, String> params) {
        ExtractData data = new ExtractData();
        // Extract text
        data.setContent(extractedText);
        return data;
    }
}
```

        tasks.register("checkstyleApi", Checkstyle.class, task -> {
            task.source(extension.getDocumentedSource());
            // TODO: This is ugly
            task.setConfig(project.getResources().getText().fromFile(checkstyle.getConfigDirectory().file("checkstyle-api.xml")));
            task.setClasspath(layout.files());

        // simple bean? assumes string constructor
        if (parser.next() == XmlPullParser.TEXT) {
            final String text = parser.getText();

            // confirm element doesn't contain nested XML
            if (parser.next() != XmlPullParser.START_TAG) {
                return convertText(text, clazz == rawType ? toType : TypeLiteral.get(clazz));

      Iterators.advance(iterator, position);
      return Iterators.getNext(iterator, defaultValue);
    }
  }

  /**
   * Returns the first element in {@code iterable} or {@code defaultValue} if the iterable is empty.
   * The {@link Iterators} analog to this method is {@link Iterators#getNext}.
   *
   * <p>If no default value is desired (and the caller instead wants a {@link

    protected Object parsePrimitive(final JsonParser jsonParser) throws IOException {
        final JsonToken token = jsonParser.getCurrentToken();
        return switch (token) {
        case VALUE_STRING -> jsonParser.getText();
        case VALUE_NUMBER_INT -> jsonParser.getLongValue();
        case VALUE_NUMBER_FLOAT -> jsonParser.getDoubleValue();
        case VALUE_TRUE -> true;
        case VALUE_FALSE -> false;

crawler.awaitTermination();
System.out.println("Crawling completed");
```

### Custom Content Extractor

```java
public class CustomExtractor extends AbstractExtractor {
    @Override
    public ExtractData getText(final InputStream inputStream, final Map<String, String> params) {
        // Custom extraction logic
        ExtractData extractData = new ExtractData();
        // ... implementation
        return extractData;
    }

                n++;
                final int size = chain.size();
                final int cost = chain.getCreditCost();
                final CommonServerMessageBlockRequest next = chain.getNext();
                if (log.isTraceEnabled()) {
                    log.trace(String.format("%s costs %d avail %d (%s)", chain.getClass().getName(), cost, this.credits.availablePermits(),
                            this.name));

        this.overrideTimeout = overrideTimeout;
    }
