public sealed class Key : IMessage<Key>, IEquatable<Key>, IDeepCloneable<Key>, IBufferMessage, IMessage
Reference documentation and code samples for the Google Cloud Data Loss Prevention v2 API class Key.
A unique identifier for a Datastore entity.
If a key's partition ID or any of its path kinds or names are
reserved/read-only, the key is reserved/read-only.
A reserved/read-only key is forbidden in certain documented contexts.
public RepeatedField<Key.Types.PathElement> Path { get; }
The entity path.
An entity path consists of one or more elements composed of a kind and a
string or numerical identifier, which identify entities. The first
element identifies a root entity, the second element identifies
a child of the root entity, the third element identifies a child of the
second entity, and so forth. The entities identified by all prefixes of
the path are called the element's ancestors.
A path can never be empty, and a path can have at most 100 elements.
