Of(IEnumerable<string>)
Derives the revision of a policy from the statements it is made of.
public static SenderTrustPolicyRevision Of(IEnumerable<string> statements)Parameters
statementsIEnumerable<string>Every statement the policy verifies by, each already in its comparison form.
Returns
- SenderTrustPolicyRevision
The revision, which is None when the policy verifies nothing.
Remarks
The statements are sorted and joined with a separator none of them may contain, so the revision follows what a policy says rather than the order an operator happened to write it in — reordering a list is not a change to it, and a deployment that reordered one must not have every later verdict read as reached under a different policy. A policy with nothing to say verifies nothing and is deliberately indistinguishable from no policy at all.
