VOLK_PARSER_COMMON_H

#define VOLK_PARSER_COMMON_H

Definition at line 13 of file parser_nt.c.

YYCTYPE

#define YYCTYPE   uint8_t

TTL is UTF-8 encoded.

char should be considered to be UTF-8 throughout this library, however, setting YYCTYPE to char generates case labels outside of the char range.

nt_parse_term()

VOLK_rc nt_parse_term	(	const char *	rep,
		VOLK_Term **	term )

Parse a single term.

Parameters

[in]	rep	N-Triples representation as a character string.
[out]	RDF term and triple module	Term to be created from the string.

Returns

VOLK_OK on success, VOLK_VALUE_ERR if the string is not valid N-Triples syntax for a IRI ref, Literal or BNode.

nt_parse_doc()

VOLK_rc nt_parse_doc	(	FILE *	fh,
		const char *	sh,
		VOLK_Graph *	gr,
		size_t *	ct,
		char **	err )

Parse an RDF document in N-Triples format.

Either an open file handle or an in-memory string can be passed for parsing.

Parameters

[in]	fh	N-Triples doc file handle. Exclusive with sh.
[in]	sh	N-Triples doc string handle. Exclusive with fh.
[out]	gr	Graph handle to be populated. The graph MUST be initialized and MAY be not empty.
[out]	ct	If not NULL it is populated with the number of triples parsed. This may be more than the triples in the resulting graph.
[out]	err	String handle to be populated with an error message.

Returns

VOLK_OK on success, VOLK_VALUE_ERR if a parsing error was encountered. On error, err will contain the error message.
