@Override
    public Collection<Form> getConnectionGroupAttributes() {
        return Collections.<Form>emptyList();
    }
{@inheritDoc}

<p>This implementation simply returns an empty {@link Collection}.
Implementations that wish to expose custom connection group attributes
as fields within connection group edit screens should override this
function.
