Struct Documentation

struct RDFFileParser

Similar to rdf4cpp::parser::IStreamQuadIterator Parses the file by the given path and tries to extract Quads given in TURTLE format.

Example:

for (const auto& e : rdf4cpp::parser::RDFFileParser{"somewhere.ttl"}) {
 if (e.has_value())
    std::cout << e.value();
 else
    std::cout << e.error();
}

Note

the iterator starts on the first Quad

Note

An exhausted iterator becomes the end-of-stream iterator.

Warning

The value pointed to by an end-of-stream iterator is undefined
