5.10.1 Events¶

struct SerdBaseEvent¶

Event for base URI changes.

Emitted whenever the base URI changes.

SerdEventType type¶: SerdEventType.SERD_BASE

const SerdNode *uri¶: Base URI.

struct SerdPrefixEvent¶

Event for namespace definitions.

Emitted whenever a prefix is defined.

SerdEventType type¶: SerdEventType.SERD_PREFIX

const SerdNode *name¶: Prefix name.

const SerdNode *uri¶: Namespace URI.

struct SerdStatementEvent¶

Event for statements.

Emitted for every statement.

SerdEventType type¶: SerdEventType.SERD_STATEMENT

SerdStatementFlags flags¶: Flags for pretty-printing.

const SerdStatement *statement¶: Statement.

struct SerdEndEvent¶

Event for the end of anonymous node descriptions.

This is emitted to indicate that the given anonymous node will no longer be described. This is used by the writer which may, for example, need to write a delimiter.

SerdEventType type¶: SerdEventType.SERD_END

const SerdNode *node¶: Anonymous node that is finished.

union SerdEvent¶

An event in a data stream.

Streams of data are represented as a series of events. Events represent everything that can occur in an RDF document, and are used to plumb together different components. For example, when parsing a document, a reader emits a stream of events which can be sent to a writer to rewrite a document, or to an inserter to build a model in memory.

SerdEventType type¶: Event type (always set)

SerdBaseEvent base¶: Base URI changed.

SerdPrefixEvent prefix¶: New namespace prefix.

SerdStatementEvent statement¶: Statement.

SerdEndEvent end¶: End of anonymous node.

enum SerdEventType¶

Type of a SerdEvent.

enumerator SERD_BASE¶: Base URI changed.

enumerator SERD_PREFIX¶: New URI prefix.

enumerator SERD_STATEMENT¶: Statement.

enumerator SERD_END¶: End of anonymous node.

enum SerdStatementFlag¶

Flags indicating inline abbreviation information for a statement.

enumerator SERD_EMPTY_S¶: Empty blank node subject.

enumerator SERD_EMPTY_G¶: Empty blank node graph.

enumerator SERD_ANON_S¶: Start of anonymous subject.

enumerator SERD_ANON_O¶: Start of anonymous object.

enumerator SERD_LIST_S¶: Start of list subject.

enumerator SERD_LIST_O¶: Start of list object.

enumerator SERD_TERSE_S¶: Start of terse subject.

enumerator SERD_TERSE_O¶: Start of terse object.

typedef uint32_t SerdStatementFlags¶: Bitwise OR of SerdStatementFlag values.

typedef SerdStatus (*SerdEventFunc)(void *handle, const SerdEvent *event)¶: Function for handling events.
