public sealed class ResourceReference : IMessage<ResourceReference>, IEquatable<ResourceReference>, IDeepCloneable<ResourceReference>, IBufferMessage, IMessage
Defines a proto annotation that describes a string field that refers to
an API resource.
The resource type of a child collection that the annotated field
references. This is useful for annotating the parent field that
doesn't have a fixed resource type.
