bool serialize_trig(writer::BufWriterParts writer) const noexcept¶

Serialize this dataset as TriG. This function will internally create a SerializationState and call begin and flush on it when appropriate.

Parameters:: writer – writer parts
Returns:: true if serialization was successful, false if a call to W::flush was not able to make room

Dataset anonymize(util::Anonymizer &anonymizer) const¶

Anonymize the dataset by removing all information except for the dataset structure itself.

See rdf4cpp::util::Anonymizer for details

Public Members

template<typename ErrF = decltype([](parser::ParsingError) noexcept {})> void load_rdf_data(std::istream &rdf_file, parser::ParsingFlags flags=parser::ParsingFlags::none(), parser::ParsingState *state=nullptr, ErrF &&errf={}) requires std bool serialize_trig (writer::SerializationState &state, writer::BufWriterParts writer) const noexcept

Serialize this dataset as N-Quads.

Param writer:: writer parts
Param state:: serialization state
Param writer:: writer parts
Return:: true if serialization was successful, false if a call to flush was not able to make room Serialize this dataset as TriG. This function does not call begin or flush on the given state, it just serialized the contents of this Dataset using it.
Return:: true if serialization was successful, false if a call to W::flush was not able to make room
