raptor_new_parser ()

raptor_parser *
raptor_new_parser (raptor_world *world,
                   const char *name);

Constructor - create a new raptor_parser object.

raptor_new_parser_for_content ()

raptor_parser *
raptor_new_parser_for_content (raptor_world *world,
                               raptor_uri *uri,
                               const char *mime_type,
                               const char *buffer,
                               size_t len,
                               const unsigned char *identifier);

Constructor - create a new raptor_parser.

Uses raptor_world_guess_parser_name() to find a parser by scoring recognition of the syntax by a block of characters, the content identifier or a mime type. The content identifier is typically a filename or URI or some other identifier.

raptor_free_parser ()

void
raptor_free_parser (raptor_parser *parser);

Destructor - destroy a raptor_parser object.

raptor_graph_mark_handler ()

void
(*raptor_graph_mark_handler) (void *user_data,
                              raptor_uri *graph,
                              int flags);

Graph start/end mark handler function.

Records start and end of graphs happening in a stream of generated raptor_statement via the statement handler. The callback starts a graph when flags has RAPTOR_GRAPH_MARK_START bit set.

The start and ends may be either declared in the syntax via some keyword or mechanism such as TRiG {} syntax when flags has bit RAPTOR_GRAPH_MARK_DECLARED set, or be implied by the start/end of the data in other syntaxes, and the bit will be unset.

raptor_namespace_handler ()

void
(*raptor_namespace_handler) (void *user_data,
                             raptor_namespace *nspace);

XML Namespace declaration reporting handler set by raptor_parser_set_namespace_handler().

raptor_parser_set_statement_handler ()

void
raptor_parser_set_statement_handler (raptor_parser *parser,
                                     void *user_data,
                                     raptor_statement_handler handler);

Set the statement handler function for the parser.

Use this to set the function to receive statements as the parsing proceeds. The statement argument to handler is shared and must be copied by the caller with raptor_statement_copy().

raptor_parser_set_graph_mark_handler ()

void
raptor_parser_set_graph_mark_handler (raptor_parser *parser,
                                      void *user_data,
                                      raptor_graph_mark_handler handler);

Set the graph mark handler function for the parser.

See raptor_graph_mark_handler and raptor_graph_mark_flags for the marks that may be returned by the handler.

raptor_parser_set_namespace_handler ()

void
raptor_parser_set_namespace_handler (raptor_parser *parser,
                                     void *user_data,
                                     raptor_namespace_handler handler);

Set the namespace handler function for the parser.

When a prefix/namespace is seen in a parser, call the given handler with the prefix string and the raptor_uri namespace URI. Either can be NULL for the default prefix or default namespace.

The handler function does not deal with duplicates so any namespace may be declared multiple times.

raptor_parser_get_description ()

const raptor_syntax_description *
raptor_parser_get_description (raptor_parser *rdf_parser);

Get description of the syntaxes of the parser.

The returned description is static and lives as long as the raptor library (raptor world).

raptor_parser_get_locator ()

raptor_locator *
raptor_parser_get_locator (raptor_parser *rdf_parser);

Get the current raptor locator object.

raptor_parser_parse_abort ()

void
raptor_parser_parse_abort (raptor_parser *rdf_parser);

Abort an ongoing parsing.

Causes any ongoing generation of statements by a parser to be terminated and the parser to return controlto the application as soon as draining any existing buffers.

Most useful inside raptor_parser_parse_file() or raptor_parser_parse_uri() when the Raptor library is directing the parsing and when one of the callback handlers such as as set by raptor_parser_set_statement_handler() requires to return to the main application code.

raptor_parser_parse_chunk ()

int
raptor_parser_parse_chunk (raptor_parser *rdf_parser,
                           const char *buffer,
                           size_t len,
                           int is_end);

Parse a block of content into triples.

This method can only be called after raptor_parser_parse_start() has initialised the parser.

raptor_parser_parse_file ()

int
raptor_parser_parse_file (raptor_parser *rdf_parser,
                          raptor_uri *uri,
                          raptor_uri *base_uri);

Parse RDF content at a file URI.

If uri is NULL (source is stdin), then the base_uri is required.

raptor_parser_parse_file_stream ()

int
raptor_parser_parse_file_stream (raptor_parser *rdf_parser,
                                 FILE *stream,
                                 const char *filename,
                                 raptor_uri *base_uri);

Parse RDF content from a FILE*.

After draining the FILE* stream (EOF), fclose is not called on it.

raptor_parser_parse_iostream ()

int
raptor_parser_parse_iostream (raptor_parser *rdf_parser,
                              raptor_iostream *iostr,
                              raptor_uri *base_uri);

Parse content from an iostream

If the parser requires a base URI and base_uri is NULL, an error will be generated and the function will fail.

raptor_parser_parse_start ()

int
raptor_parser_parse_start (raptor_parser *rdf_parser,
                           raptor_uri *uri);

Start a parse of content with base URI.

Parsers that need a base URI can be identified using a syntax description returned by raptor_world_get_parser_description() statically or raptor_parser_get_description() on a constructed parser.

raptor_parser_parse_uri ()

int
raptor_parser_parse_uri (raptor_parser *rdf_parser,
                         raptor_uri *uri,
                         raptor_uri *base_uri);

Parse the RDF content at URI.

Sends an HTTP Accept: header whent the URI is of the HTTP protocol, see raptor_parser_parse_uri_with_connection() for details including how the base_uri is used.

raptor_parser_parse_uri_with_connection ()

int
raptor_parser_parse_uri_with_connection
                               (raptor_parser *rdf_parser,
                                raptor_uri *uri,
                                raptor_uri *base_uri,
                                void *connection);

Parse RDF content at URI using existing WWW connection.

If base_uri is not given and during resolution of the URI, a protocol redirection occurs, the final resolved URI will be used as the base URI. If redirection does not occur, the base URI will be uri .

If base_uri is given, it overrides the process above.

When connection is NULL and a MIME Type exists for the parser type, this type is sent in an HTTP Accept: header in the form Accept: MIME-TYPE along with a wildcard of 0.1 quality, so MIME-TYPE is prefered rather than the sole answer. The latter part may not be necessary but should ensure an HTTP 200 response.

raptor_parser_get_graph ()

raptor_uri *
raptor_parser_get_graph (raptor_parser *rdf_parser);

Get the current graph for the parser

The returned URI is owned by the caller and must be freed with raptor_free_uri()

raptor_parser_get_name ()

const char *
raptor_parser_get_name (raptor_parser *rdf_parser);

Get the name of a parser.

Use raptor_parser_get_description() to get the alternate names and aliases as well as other descriptive values.

raptor_parser_set_option ()

int
raptor_parser_set_option (raptor_parser *parser,
                          raptor_option option,
                          const char *string,
                          int integer);

Set parser option.

If string is not NULL and the option type is numeric, the string value is converted to an integer and used in preference to integer .

If string is NULL and the option type is not numeric, an error is returned.

The string values used are copied.

The allowed options are available via raptor_world_get_option_description().

raptor_parser_get_option ()

int
raptor_parser_get_option (raptor_parser *parser,
                          raptor_option option,
                          char **string_p,
                          int *integer_p);

Get parser option.

Any string value returned in *string_p is shared and must be copied by the caller.

The allowed options are available via raptor_world_get_option_description().

raptor_parser_get_accept_header ()

const char *
raptor_parser_get_accept_header (raptor_parser *rdf_parser);

Get an HTTP Accept value for the parser.

The returned string must be freed by the caller such as with raptor_free_memory().

raptor_parser_set_uri_filter ()

void
raptor_parser_set_uri_filter (raptor_parser *parser,
                              raptor_uri_filter_func filter,
                              void *user_data);

Set URI filter function for WWW retrieval.
