public sealed class ExpirationPolicy : IMessage<ExpirationPolicy>, IEquatable<ExpirationPolicy>, IDeepCloneable<ExpirationPolicy>, IBufferMessage, IMessage
A policy that specifies the conditions for resource expiration (i.e.,
automatic resource deletion).
Specifies the "time-to-live" duration for an associated resource. The
resource expires if it is not active for a period of ttl. The definition
of "activity" depends on the type of the associated resource. The minimum
and maximum allowed values for ttl depend on the type of the associated
resource, as well. If ttl is not set, the associated resource never
expires.
