public sealed class ObjectId : IMessage<ObjectId>, IEquatable<ObjectId>, IDeepCloneable<ObjectId>, IBufferMessage, IMessage
Reference documentation and code samples for the Certificate Authority v1 API class ObjectId.
An [ObjectId][google.cloud.security.privateca.v1.ObjectId] specifies an
object identifier (OID). These provide context and describe types in ASN.1
messages.
