### CrawlerThread (`CrawlerThread.java`)

Worker thread for crawling.

* Support for complex user authentication systems, **database connections**, etc.
* **No compromise** with databases, frontends, etc. But easy integration with all of them.

### Unlimited "plug-ins" { #unlimited-plug-ins }

Or in other way, no need for them, import and use the code you need.

     *
     * @param paramMap the data store parameters
     * @param dataMap the data map containing crawling configuration
     * @return the maximum access count (-1 for unlimited, 1 for single access, or specified count)
     */
    protected long getMaxAccessCount(final DataStoreParams paramMap, final Map<String, Object> dataMap) {

* **Никаких компромиссов** с базами данных, интерфейсами и т. д. Но при этом — лёгкая интеграция со всеми ними.

### Нет ограничений на "Плагины" { #unlimited-plug-ins }

Или, другими словами, нет необходимости в них — просто импортируйте и используйте нужный вам код.

* Unterstützung für komplexe Authentifizierungssysteme, **Datenbankverbindungen**, usw.
* **Keine Kompromisse** bei Datenbanken, Frontends, usw., sondern einfache Integration mit allen.

### Unbegrenzte Erweiterungen { #unlimited-plug-ins }

Oder mit anderen Worten, sie werden nicht benötigt. Importieren und nutzen Sie den Code, den Sie brauchen.

    assertThat(removalListener.getCount()).isEqualTo(MAX_SIZE);
    CacheTesting.checkValidState(cache);
  }

* Soporte para sistemas de autenticación de usuario complejos, **conexiones a bases de datos**, etc.
* **Sin compromisos** con bases de datos, frontends, etc. Pero fácil integración con todos ellos.

### "Plug-ins" ilimitados { #unlimited-plug-ins }

O de otra manera, no hay necesidad de ellos, importa y usa el código que necesitas.

* Suporte para sistemas de autenticação complexos, **conexões com banco de dados** etc.
* **Sem comprometer** os bancos de dados, frontends etc. Mas fácil integração com todos eles.
