I was looking through the symfony source files.and I saw this in Symfony\Bundle\SecurityBundle\Resources\config\Security.xml:
<service id='security.role_hierarchy' ... >
<argument>%security.role_hierarchy.roles%</arguments>
my question is about the %security.role_hierarchy.roles%
paramater.this is the parameter provided by the user in the app/config/security.*ml under the role_hierarchy
key. however I don't understand how that will resolve to 'security.role_hierarchy.roles'
.
