SerdModel *serd_model_new(SerdWorld *world, SerdModelFlags flags)¶

Create a new model.

Parameters

world – The world in which to make this model.
flags – Model options, including enabled indices, for example SERD_SPO | SERD_OPS. Be sure to enable an index where the most significant node(s) are not variables in your queries. For example, to make (? P O) queries, enable either SERD_OPS or SERD_POS.

SerdModel *serd_model_copy(const SerdModel *model)¶: Return a deep copy of model

bool serd_model_equals(const SerdModel *a, const SerdModel *b)¶: Return true iff a is equal to b, ignoring statement cursor metadata.

void serd_model_free(SerdModel *model)¶: Close and free model

SerdWorld *serd_model_world(SerdModel *model)¶: Get the world associated with model

SerdModelFlags serd_model_flags(const SerdModel *model)¶: Get the flags enabled on model

size_t serd_model_size(const SerdModel *model)¶: Return the number of statements stored in model

bool serd_model_empty(const SerdModel *model)¶: Return true iff there are no statements stored in model

SerdIter *serd_model_begin(const SerdModel *model)¶: Return an iterator to the start of model

const SerdIter *serd_model_end(const SerdModel *model)¶: Return an iterator to the end of model

SerdRange *serd_model_all(const SerdModel *model, const SerdStatementOrder order)¶: Return a range of all statements in model

SerdIter *serd_model_find(const SerdModel *model, const SerdNode *s, const SerdNode *p, const SerdNode *o, const SerdNode *g)¶

Search for statements by a quad pattern.

Returns: An iterator to the first match, or NULL if no matches found.

SerdRange *serd_model_range(const SerdModel *model, const SerdNode *s, const SerdNode *p, const SerdNode *o, const SerdNode *g)¶

Search for statements by a quad pattern.

Returns: A range containing all matching statements.

const SerdNode *serd_model_get(const SerdModel *model, const SerdNode *s, const SerdNode *p, const SerdNode *o, const SerdNode *g)¶

Search for a single node that matches a pattern.

Exactly one of s, p, o must be NULL. This function is mainly useful for predicates that only have one value. :returns: The first matching node, or NULL if no matches are found.

const SerdStatement *serd_model_get_statement(const SerdModel *model, const SerdNode *s, const SerdNode *p, const SerdNode *o, const SerdNode *g)¶

Search for a single statement that matches a pattern.

This function is mainly useful for predicates that only have one value.

Returns: The first matching statement, or NULL if none are found.

bool serd_model_ask(const SerdModel *model, const SerdNode *s, const SerdNode *p, const SerdNode *o, const SerdNode *g)¶: Return true iff a statement exists.

size_t serd_model_count(const SerdModel *model, const SerdNode *s, const SerdNode *p, const SerdNode *o, const SerdNode *g)¶: Return the number of matching statements.

SerdStatus serd_model_add(SerdModel *model, const SerdNode *s, const SerdNode *p, const SerdNode *o, const SerdNode *g)¶

Add a statement to a model from nodes.

This function fails if there are any active iterators on model.

SerdStatus serd_model_insert(SerdModel *model, const SerdStatement *statement)¶

Add a statement to a model.

This function fails if there are any active iterators on model. If statement is null, then SERD_FAILURE is returned.

SerdStatus serd_model_add_range(SerdModel *model, SerdRange *range)¶

Add a range of statements to a model.

This function fails if there are any active iterators on model.

SerdStatus serd_model_erase(SerdModel *model, SerdIter *iter)¶

Remove a quad from a model via an iterator.

Calling this function invalidates all iterators on model except iter.

Parameters

model – The model which iter points to.
iter – Iterator to the element to erase, which is incremented to the next value on return.

SerdStatus serd_model_erase_range(SerdModel *model, SerdRange *range)¶

Remove a range from a model.

Calling this function invalidates all iterators on model except iter.

Parameters

model – The model which range points to.
range – Range to erase, which will be empty on return;

SerdValidatorChecks serd_validator_checks_enable(const SerdValidatorChecks checks, const char*)¶

SerdValidatorChecks serd_validator_checks_disable(SerdValidatorChecks checks, const char*)¶

SerdValidator *serd_validator_new(SerdWorld *world)¶

void serd_validator_free(SerdValidator *validator)¶: Free validator

SerdStatus serd_validator_enable_checks(SerdValidator *validator, const char *pattern)¶

SerdStatus serd_validator_disable_checks(SerdValidator *validator, const char *pattern)¶

SerdStatus serd_validate_model(SerdValidator *const validator, const SerdModel *model, const SerdNode *graph)¶

Validate model.

This performs validation based on the XSD, RDF, RDFS, and OWL vocabularies. All necessary data, including those vocabularies and any property/class definitions that use them, are assumed to be in model.

Validation errors are reported to the world’s error sink.

Parameters

validator – Validator configured to run the desired checks.
model – The model to run the validator on.
graph – Optional graph to check. Is this is non-null, then top-level checks will be initiated only by statements in the given graph. The entire model is still searched while running a check so that, for example, schemas that define classes and properties can be stored in separate graphs. If this is null, then the validator simply ignores graphs and searches the entire model for everything.

Returns

SerdStatus.SERD_SUCCESS if no errors are found, or SerdStatus.SERD_ERR_INVALID if validation checks failed.
