// This file implements VisitProtoFields() functions for sync protos.
//
// VisitProtoFields(visitor, proto) calls |visitor| for each field in
// |proto|. When called, |visitor| gets passed |proto|, field name and
// field value.
//
// VisitProtoFields() used to implement two distinctive features:
// 1. Serialization into base::DictionaryValue
// 2. Proto memory usage estimation
//
// To achieve that it's very important for VisitProtoFields() to be free
// of any logic. It must just call visitor for each field in a proto.
//
// Logic (like clobbering sensitive fields) must be implemented in visitors.
// For example see how ToValueVisitor (from proto_value_conversions.cc)
// implements various customizations.

#define VISIT_(Kind, field) \
  if (proto.has_##field()) \
    visitor.Visit##Kind(proto, #field, proto.field())

// Generic version, calls visitor.Visit(). Handles almost everything except
// for special cases below.
#define VISIT(field) VISIT_(, field)

// 'bytes' protobuf type maps to std::string, and is indistinguishable
// from 'string' type. To solve that 'bytes' fields are special cased to
// call visitor.VisitBytes().
#define VISIT_BYTES(field) VISIT_(Bytes, field)

// We could use template magic (std::is_enum) to handle enums, but that would
// complicate visitors, and besides we already have special case for 'bytes',
// so just add one more special case. Calls visitor.VisitEnum().
#define VISIT_ENUM(field) VISIT_(Enum, field)

// Repeated fields are always present, so there are no 'has_<field>' methods.
// This macro unconditionally calls visitor.Visit().
#define VISIT_REP(field) \
  visitor.Visit(proto, #field, proto.field());

// NOLINT(runtime/references) is necessary to avoid a presubmit warning about
// V& not being const.
#define VISIT_PROTO_FIELDS(proto) \
  template <class V>              \
  void VisitProtoFields(V& visitor, proto)  // NOLINT(runtime/references)
