◆ serd_chunk_sink()
| SERD_API size_t serd_chunk_sink | ( | const void *SERD_NONNULL | buf, |
| size_t | len, | ||
| void *SERD_NONNULL | stream ) |
A convenience sink function for writing to a string
This function can be used as a SerdSink to write to a SerdChunk which is resized as necessary with realloc(). The stream parameter must point to an initialized SerdChunk. When the write is finished, the string should be retrieved with serd_chunk_sink_finish().
◆ serd_chunk_sink_finish()
| SERD_API uint8_t *SERD_NULLABLE serd_chunk_sink_finish | ( | SerdChunk *SERD_NONNULL | stream | ) |
Finish a serialisation to a chunk with serd_chunk_sink().
The returned string is the result of the serialisation, which is null terminated (by this function) and owned by the caller.
◆ serd_file_sink()
| SERD_API size_t serd_file_sink | ( | const void *SERD_NONNULL | buf, |
| size_t | len, | ||
| void *SERD_NONNULL | stream ) |
A convenience sink function for writing to a FILE*.
This function can be used as a SerdSink when writing to a FILE*. The stream parameter must be a FILE* opened for writing.
◆ serd_writer_chop_blank_prefix()
| SERD_API void serd_writer_chop_blank_prefix | ( | SerdWriter *SERD_NONNULL | writer, |
| const uint8_t *SERD_NULLABLE | prefix ) |
Set a prefix to be removed from matching blank node identifiers
This is the counterpart to serd_reader_add_blank_prefix() which can be used to "undo" added prefixes.
◆ serd_writer_end_anon()
| SERD_API SerdStatus serd_writer_end_anon | ( | SerdWriter *SERD_NONNULL | writer, |
| const SerdNode *SERD_NULLABLE | node ) |
Mark the end of an anonymous node's description.
Note this function can be safely casted to SerdEndSink.
◆ serd_writer_finish()
| SERD_API SerdStatus serd_writer_finish | ( | SerdWriter *SERD_NONNULL | writer | ) |
Finish a write
This flushes any pending output, for example terminating punctuation, so that the output is a complete document.
◆ serd_writer_free()
| SERD_API void serd_writer_free | ( | SerdWriter *SERD_NULLABLE | writer | ) |
Free writer.
◆ serd_writer_get_env()
| SERD_PURE_API SerdEnv *SERD_NONNULL serd_writer_get_env | ( | SerdWriter *SERD_NONNULL | writer | ) |
Return the env used by writer.
◆ serd_writer_new()
| SERD_API SerdWriter *SERD_ALLOCATED serd_writer_new | ( | SerdSyntax | syntax, |
| SerdStyle | style, | ||
| SerdEnv *SERD_NONNULL | env, | ||
| const SerdURI *SERD_NULLABLE | base_uri, | ||
| SerdSink SERD_NONNULL | ssink, | ||
| void *SERD_NULLABLE | stream ) |
Create a new RDF writer.
◆ serd_writer_set_base_uri()
| SERD_API SerdStatus serd_writer_set_base_uri | ( | SerdWriter *SERD_NONNULL | writer, |
| const SerdNode *SERD_NULLABLE | uri ) |
Set the current output base URI, and emit a directive if applicable.
Note this function can be safely casted to SerdBaseSink.
◆ serd_writer_set_error_sink()
| SERD_API void serd_writer_set_error_sink | ( | SerdWriter *SERD_NONNULL | writer, |
| SerdErrorSink SERD_NONNULL | error_sink, | ||
| void *SERD_NULLABLE | error_handle ) |
Set a function to be called when errors occur during writing.
The error_sink will be called with handle as its first argument. If no error function is set, errors are printed to stderr.
◆ serd_writer_set_prefix()
| SERD_API SerdStatus serd_writer_set_prefix | ( | SerdWriter *SERD_NONNULL | writer, |
| const SerdNode *SERD_NONNULL | name, | ||
| const SerdNode *SERD_NONNULL | uri ) |
Set a namespace prefix (and emit directive if applicable).
Note this function can be safely casted to SerdPrefixSink.
◆ serd_writer_set_root_uri()
| SERD_API SerdStatus serd_writer_set_root_uri | ( | SerdWriter *SERD_NONNULL | writer, |
| const SerdNode *SERD_NULLABLE | uri ) |
Set the current root URI.
The root URI should be a prefix of the base URI. The path of the root URI is the highest path any relative up-reference can refer to. For example, with root file:///foo/root and base file:///foo/root/base, file:///foo/root will be written as <../>, but file:///foo will be written non-relatively as file:///foo. If the root is not explicitly set, it defaults to the base URI, so no up-references will be created at all.
◆ serd_writer_write_statement()
| SERD_API SerdStatus serd_writer_write_statement | ( | SerdWriter *SERD_NONNULL | writer, |
| SerdStatementFlags | flags, | ||
| const SerdNode *SERD_NULLABLE | graph, | ||
| const SerdNode *SERD_NONNULL | subject, | ||
| const SerdNode *SERD_NONNULL | predicate, | ||
| const SerdNode *SERD_NONNULL | object, | ||
| const SerdNode *SERD_NULLABLE | datatype, | ||
| const SerdNode *SERD_NULLABLE | lang ) |
Write a statement.
Note this function can be safely casted to SerdStatementSink.
