## Otras Anotaciones de Tipos de Retorno { #other-return-type-annotations }

Podría haber casos en los que devuelvas algo que no es un campo válido de Pydantic y lo anotes en la función, solo para obtener el soporte proporcionado por las herramientas (el editor, mypy, etc).

import org.eclipse.aether.RepositorySystemSession;
import org.eclipse.aether.RequestTrace;
import org.eclipse.aether.artifact.Artifact;
import org.eclipse.aether.artifact.DefaultArtifact;
import org.eclipse.aether.impl.ArtifactResolver;
import org.eclipse.aether.impl.RemoteRepositoryManager;
import org.eclipse.aether.impl.VersionRangeResolver;
import org.eclipse.aether.repository.RemoteRepository;

    public Map<String, Artifact> getManagedVersionMap() {
        return managedVersionMap;
    }

    @Override
    public boolean equals(Object other) {
        if (other == this) {
            return true;
        } else {
            if (other instanceof MavenProject that) {
                return Objects.equals(getArtifactId(), that.getArtifactId())

...mas continue lendo abaixo para ver como superar isso.

## Tipo de Retorno e Filtragem de Dados { #return-type-and-data-filtering }

Vamos continuar do exemplo anterior. Queríamos **anotar a função com um tipo**, mas queríamos poder retornar da função algo que realmente incluísse **mais dados**.
