std::string name () const
 the name of the codec used to identifier it in the .proto custom option extension
 
google::protobuf::FieldDescriptor::Type field_type () const
 the type exposed to the user in the original and decoded Protobuf messages More...
 
google::protobuf::FieldDescriptor::CppType wire_type () const
 the C++ type used "on the wire". This is the type visible after pre_encode and before post_decode functions are called. More...
 
const google::protobuf::FieldDescriptor * this_field () const
 Returns the FieldDescriptor (field schema meta-data) for this field. More...
 
const google::protobuf::Descriptor * this_descriptor () const
 Returns the Descriptor (message schema meta-data) for the immediate parent Message. More...

 the part of the message currently being encoded (head or body)
 
bool strict ()
 
void set_force_use_required (bool force_required=true)
 Force the codec to always use the "required" field encoding, regardless of the FieldDescriptor setting. Useful when wrapping this codec in another that handles optional and repeated fields.
 
void field_pre_encode (dccl::any *wire_value, const dccl::any &field_value)
 Pre-encodes a non-repeated (i.e. optional or required) field by converting the FieldType representation (the Google Protobuf representation) into the WireType representation (the type used in the encoded DCCL message). This allows for type-converting codecs. More...
 
void field_pre_encode_repeated (std::vector< dccl::any > *wire_values, const std::vector< dccl::any > &field_values)
 Pre-encodes a repeated field. More...
 
void field_encode (Bitset *bits, const dccl::any &field_value, const google::protobuf::FieldDescriptor *field)

 Decode a repeated field. More...
 
void field_post_decode (const dccl::any &wire_value, dccl::any *field_value)
 Post-decodes a non-repeated (i.e. optional or required) field by converting the WireType (the type used in the encoded DCCL message) representation into the FieldType representation (the Google Protobuf representation). This allows for type-converting codecs. More...
 
void field_post_decode_repeated (const std::vector< dccl::any > &wire_values, std::vector< dccl::any > *field_values)
 Post-decodes a repeated field. More...
