Abstract
In one embodiment, a method includes storing code defining access control rules for an object, the code defining each of the access control rules as a set of operations that each returns (1) when resolved, a predetermined result, and (2) when not resolved, a not definitive result indicating that it should be skipped if it is not necessary for determining the access control rule; compiling the code; compiling and loading the code; receiving a query for the object; executing the code to evaluate the corresponding operations; determining, for each access control rule, a rule-result comprising a value representing a true or a false value; determining a final result based on the one or more rule-results of the one or more access control rules, the final result indicating an allow-result or a deny-result; and sending the object when the final result evaluates to an allow-result.
