class ChainRequestPolicy

Implements a compound request policy.

When evaluating the compound policy, all of the contained rules are applied to the request. The overall result is computed according to the following rules:

<ol> <li>Returns static::DENY if any of the rules evaluated to static::DENY</li> <li>Returns static::ALLOW if at least one of the rules evaluated to static::ALLOW and none to static::DENY</li> <li>Otherwise returns NULL</li> </ol>
