Expression

public static final class Expression.FieldReference
extends com.google.protobuf.GeneratedMessageV3
implements Expression.FieldReferenceOrBuilder

 A reference to data within a structured object, supporting navigation into
 nested fields. The root_type specifies the origin of the data (input record,
 outer query, lambda parameters, or an arbitrary expression), and the
 reference_type specifies how to navigate from that root (either a direct
 path to a single element or a mask selecting multiple elements).
