Class **Phalcon\\Acl**
======================

This component allows to manage ACL lists. An access control list (ACL) is a list of permissions attached to an object. An ACL specifies which users or system processes are granted access to objects, as well as what operations are allowed on given objects.

    <?php

    $acl = new Phalcon\Acl\Adapter\Memory();
    
    //Default action is deny access
    $acl->setDefaultAction(Phalcon\Acl::DENY);
    
    //Create some roles
    $roleAdmins = new Phalcon\Acl\Role('Administrators', 'Super-User role');
    $roleGuests = new Phalcon\Acl\Role('Guests');
    
    //Add "Guests" role to acl
    $acl->addRole($roleGuests);
    
    //Add "Designers" role to acl
    $acl->addRole('Designers');
    
    //Define the "Customers" resource
    $customersResource = new Phalcon\Acl\Resource('Customers', 'Customers management');
    
    //Add "customers" resource with a couple of operations
    $acl->addResource($customersResource, 'search');
    $acl->addResource($customersResource, array('create', 'update'));
    
    //Set access level for roles into resources
    $acl->allow('Guests', 'Customers', 'search');
    $acl->allow('Guests', 'Customers', 'create');
    $acl->deny('Guests', 'Customers', 'update');
    
    //Check whether role has access to the operations
    $acl->isAllowed('Guests', 'Customers', 'edit'); //Returns 0
    $acl->isAllowed('Guests', 'Customers', 'search'); //Returns 1
    $acl->isAllowed('Guests', 'Customers', 'create'); //Returns 1
