| <p>Access modifiers for members of roles have some special interpretation: |
| |
| </p> |
| <ol> |
| <li>A private member is also visible in any implicit sub role |
| (see implicit inheritance <a href="s1.3.1.c.html" |
| title="§1.3.1.(c) Overriding and implicit inheritance" |
| class="sect">§1.3.1.(c)</a>).<br /> |
| In contrast to inner classes in Java, private members of a role are not |
| visible to the enclosing team. |
| </li> |
| <li>The default visibility of role members restricts access to the |
| current class and its sub-classes (explicit and implicit). |
| </li> |
| <li><code>protected</code> role members can only be accessed from the enclosing |
| team or via <a href="s4.html" title="§4 Callin Binding" class="sect">callin (§4)</a>. |
| </li> |
| <li><code>public</code> role members grant unrestricted access. |
| </li> |
| </ol> |
| <p>Additionally, a role always has access to all the features that its enclosing team has access to.</p> |
| <p>Only <code>public</code> members can ever be accessed via an <a href="s1.2.2.html" title="§1.2.2 Externalized roles" class="sect">externalized role (§1.2.2)</a>. |
