Otra gran funcionalidad necesaria por las APIs es la validación de datos, asegurarse de que los datos sean válidos, dados ciertos parámetros. Por ejemplo, que algún campo sea un `int`, y no algún string aleatorio. Esto es especialmente útil para los datos entrantes.

     * User controlled relocations.
     * This property is a comma separated list of entries with the syntax <code>GAV&gt;GAV</code>.
     * The first <code>GAV</code> can contain <code>*</code> for any elem (so <code>*:*:*</code> would mean ALL, something
     * you don't want). The second <code>GAV</code> is either fully specified, or also can contain <code>*</code>,
     * then it behaves as "ordinary relocation": the coordinate is preserved from relocated artifact.

## Qué Significa Activar un Entorno Virtual { #what-does-activating-a-virtual-environment-mean }

Cuando activas un entorno virtual, por ejemplo con:

//// tab | Linux, macOS

<div class="termy">

```console
$ source .venv/bin/activate
```

</div>

////

    File parent = file.getCanonicalFile().getParentFile();
    if (parent == null) {
      /*
       * The given directory is a filesystem root. All zero of its ancestors exist. This doesn't
       * mean that the root itself exists -- consider x:\ on a Windows machine without such a drive
       * -- or even that the caller can create it, but this method makes no such guarantees even for
       * non-root files.
       */

// InlineData returns whether inline data has been set.
// Note that false does not mean there is no inline data,
// only that it is unlikely.
