Interface implemented by a component that wishes to use any application-configured <tt>RolePermissionResolver</tt> that
might already exist instead of potentially creating one itself.
<p>This is mostly implemented by {@link hunt.shiro.authz.Authorizer Authorizer} and
{@link hunt.shiro.realm.Realm Realm} implementations since they
are the ones performing permission checks and need to know how to resolve Strings into
{@link hunt.shiro.authz.Permission Permission} instances.
