No exemplo anterior, como as classes eram diferentes, tivemos que usar o parâmetro `response_model`. Mas isso também significa que não temos suporte do editor e das ferramentas verificando o tipo de retorno da função.

Mas na maioria dos casos em que precisamos fazer algo assim, queremos que o modelo apenas **filtre/remova** alguns dados como neste exemplo.

 * This class extends StandardRoot to provide custom web resource handling
 * for Fess plugins, including support for plugin JAR files in the WEB-INF/plugin directory.
 */
public class FessWebResourceRoot extends StandardRoot {
    /** Logger instance for this class */
    private static final Logger logger = Logger.getLogger(FessWebResourceRoot.class.getName());

    /**

import org.slf4j.LoggerFactory;

/**
 * Use an SLF4J {@link ILoggerFactory} as a backing for a Plexus
 * {@link LoggerManager},
 * ignoring Plexus logger API parts that are not classical and probably not really used.

public class Slf4jLoggerManager implements LoggerManager {

    private final ILoggerFactory loggerFactory;

    public Slf4jLoggerManager() {

Actually, `Query`, `Path` and others you'll see next create objects of subclasses of a common `Param` class, which is itself a subclass of Pydantic's `FieldInfo` class.

And Pydantic's `Field` returns an instance of `FieldInfo` as well.

`Body` also returns objects of a subclass of `FieldInfo` directly. And there are others you will see later that are subclasses of the `Body` class.
