Member Function Documentation

◆ add() [1/3]

template<class Codec >

std::enable_if< !(std::is_base_of< google::protobuf::Message, typename Codec::wire_type >::value &&!std::is_same< google::protobuf::Message, typename Codec::wire_type >::value), void >::type dccl::FieldCodecManagerLocal::add ( const std::string & name )

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.

Definition at line 313 of file field_codec_manager.h.

◆ add() [2/3]

template<class Codec >

std::enable_if< !(std::is_base_of<google::protobuf::Message, typename Codec::wire_type>::value && !std::is_same<google::protobuf::Message, typename Codec::wire_type>::value), void>::type dccl::FieldCodecManagerLocal::add ( const std::string & name )

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.

◆ add() [3/3]

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

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

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 332 of file field_codec_manager.h.

◆ find()

std::shared_ptr<FieldCodecBase> dccl::FieldCodecManagerLocal::find	(	const google::protobuf::Descriptor *	desc,
		int	codec_version = `0`,
		std::string	name = `""`
	)		const

inline

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 130 of file field_codec_manager.h.

◆ remove() [1/3]

template<class Codec >

std::enable_if< !(std::is_base_of< google::protobuf::Message, typename Codec::wire_type >::value &&!std::is_same< google::protobuf::Message, typename Codec::wire_type >::value), void >::type dccl::FieldCodecManagerLocal::remove ( const std::string & name )

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.

Definition at line 385 of file field_codec_manager.h.

Remove 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 remove() overload.

◆ remove() [3/3]

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

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

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.
