In client-side scripts, this method will return a transaction id for the async request that can be used to cancel the request. In server-side scripts, this method will return the JSON response object (first parameter of the success or failure callbacks.)
Retrieves the security policy for the requested resource id. Note that this will return the policy in effect for this resource, which might be the policy from a parent resource if there is no explicit policy set on the requested resource. Use the isInherited method on the returned policy object to determine if the policy is inherited or not. Note that the securable resource must be within the current container, or one of its descendants.
