I have a class where on the one hand, it feels right to return an `InputStream` from a public method, e.g.

```
public class MyClass {

    private File _file;

    ...

    public InputStream getInputStream() {
        return new FileInputStream( _file );
    }
}

```

However, I'm also very cautious about doing this, as it puts the onus on the caller to close this stream. What ways can I potentially avoid this problem?
