Detailed Description

A class for managing the various field codecs. Here you can add and remove field codecs. The DCCL Codec and DefaultMessageCodec use the find() methods to locate the appropriate field codec.

Member Function Documentation

◆ add() [1/3]

template<class Codec , google::protobuf::FieldDescriptor::Type type>

void dccl::FieldCodecManager::add ( const std::string & name )

static

Add a new field codec only valid for a specific google::protobuf::FieldDescriptor::Type. This is useful if a given codec is designed to work with only a specific Protobuf type that shares an underlying C++ type (e.g. Protobuf types bytes and string)

Template Parameters

Codec	A child of FieldCodecBase
type	The google::protobuf::FieldDescriptor::Type enumeration that this codec works on.

Parameters

name	Name to use for this codec. Corresponds to (dccl.field).codec="name" in .proto file.

Definition at line 258 of file field_codec_manager.h.

◆ add() [2/3]

template<class Codec >

static boost::enable_if< boost::mpl::and_<boost::is_base_of<google::protobuf::Message, typename Codec::wire_type>, boost::mpl::not_<boost::is_same<google::protobuf::Message, typename Codec::wire_type> > >, void>::type dccl::FieldCodecManager::add	(	const std::string &	name,
		compiler::dummy_fcm< 0 >	dummy_fcm = `0`
	)

static

Add a new field codec (used for codecs operating on statically generated Protobuf messages, that is, children of google::protobuf::Message but not google::protobuf::Message itself).

Template Parameters

Codec A child of FieldCodecBase

Parameters

name	Name to use for this codec. Corresponds to (dccl.field).codec="name" in .proto file.

Returns: nothing (void). Return templates are used for template metaprogramming selection of the proper add() overload.

◆ add() [3/3]

template<class Codec >

		compiler::dummy_fcm< 1 >	dummy_fcm = `0`
	)

static

Add a new field codec (used for codecs operating on all types except statically generated Protobuf messages).

Template Parameters

Codec A child of FieldCodecBase

Parameters

name	Name to use for this codec. Corresponds to (dccl.field).codec="name" in .proto file.

Returns: nothing (void). Return templates are used for template metaprogramming selection of the proper add() overload.

Definition at line 252 of file field_codec_manager.h.

◆ find()

static boost::shared_ptr<FieldCodecBase> dccl::FieldCodecManager::find	(	const google::protobuf::Descriptor *	desc,
		std::string	name = `""`
	)

inlinestatic

Find the codec for a given base (or embedded) message.

Parameters

desc	Message descriptor to find codec for
name	Codec name (used for embedded messages to prefer the codec listed as a field option). Omit for finding the codec of a base message (one that is not embedded).

Definition at line 138 of file field_codec_manager.h.

◆ remove() [1/3]

template<class Codec , google::protobuf::FieldDescriptor::Type type>

void dccl::FieldCodecManager::remove ( const std::string & name )

static

Remove a new field codec only valid for a specific google::protobuf::FieldDescriptor::Type. This is useful if a given codec is designed to work with only a specific Protobuf type that shares an underlying C++ type (e.g. Protobuf types bytes and string)

Template Parameters

Codec	A child of FieldCodecBase
type	The google::protobuf::FieldDescriptor::Type enumeration that this codec works on.

Parameters

name	Name to use for this codec. Corresponds to (dccl.field).codec="name" in .proto file.

		compiler::dummy_fcm< 0 >	dummy_fcm = `0`
	)

static

Remove a new field codec (used for codecs operating on statically generated Protobuf messages, that is, children of google::protobuf::Message but not google::protobuf::Message itself).

Template Parameters

Codec A child of FieldCodecBase

Parameters

name	Name to use for this codec. Corresponds to (dccl.field).codec="name" in .proto file.

Returns: nothing (void). Return templates are used for template metaprogramming selection of the proper remove() overload.
