const p = ['eve', 'data3', 'read']
const added = await e.addPolicy(...p)
$added = $e->addPolicy('eve', 'data3', 'read');

AddPolicies()

AddPolicies adds authorization rules to the current policy. The operation is atomic in nature. Hence, if authorization rules consists of rules which are not consistent with the current policy, the function returns false and no policy rule is added to the current policy. If all authorization the rules are consistent with the policy rules, the function returns true and each policy rule is added to the current policy.

For example:

Hence, if authorization rules consists of rules which are not consistent with the current policy, the function returns false and no policy rule is added to the current policy. If all authorization the rules are consistent with the policy rules, the function returns true and each policy rule is added to the current policy.

For example:

rules := [][] string {
                []string {"jack", "data4", "read"},
