public sealed class EntityId : IMessage<EntityId>, IEquatable<EntityId>, IDeepCloneable<EntityId>, IBufferMessage, IMessage
Reference documentation and code samples for the Google Cloud Data Loss Prevention v2 API class EntityId.
An entity in a dataset is a field or set of fields that correspond to a
single person. For example, in medical records the EntityId might be a
patient identifier, or for financial records it might be an account
identifier. This message is used when generalizations or analysis must take
into account that multiple rows correspond to the same entity.
