Function Documentation

◆ VOLK_graph_new()

VOLK_Graph * VOLK_graph_new	(	VOLK_Store *	store,
		const char *	uri_str )

Create new graph.

Parameters

[in]	store	Back end store handle. It may be the result of VOLK_store_new(), or NULL; in the latter case, it defaults to a temporary HTable store that is freed together with the graph.
[in]	uri_str	URI string of the new graph. It MUST be a non-prefixed URI. For a namespace-prefixed URI, use VOLK_graph_new_ns(). If NULL, a UUID4 URN is generated.

Returns: New graph, or NULL on error. Must be freed with VOLK_graph_free().

Definition at line 44 of file graph.c.

◆ VOLK_graph_new_ns()

VOLK_Graph * VOLK_graph_new_ns	(	VOLK_Store *	store,
		const char *	ns_str )

inline

Create an empty graph using a namespace-prefixed string for its URI.

Parameters

[in]	store	Back end store handle. It may be the result of VOLK_store_new(), or NULL; in the latter case, it defaults to a temporary HTable store that is freed together with the graph.
[in]	ns_str	URI string of the new graph. It MUST be a namespace- prefixed URI registered in the global namespace map. It cannot be NULL.

Returns: New graph, or NULL on error. Must be freed with VOLK_graph_free().

Definition at line 54 of file graph.h.

◆ VOLK_graph_get_txn()

VOLK_Graph * VOLK_graph_get_txn	(	void *	txn,
		VOLK_Store *	store,
		const VOLK_Term *	uri,
		size_t *	ct )

Create a temp graph from stored triples.

The new graph is stored in a hash map and is made up of all the triples found in the store with the given context URI. The new graph URI is the same as the given context.

Parameters

[in]	txn	Transaction handle. If not NULL, new child transaction will be opened under the one provided.
[in]	store	Back end store handle.
[in]	uri	URI of the graph to retrieve.
[out]	ct	If not NULL, it will be populated with the number of triples found. TODO deprecate. VOLK_graph_size() does the same.

Returns: New graph handle. It must be freed by the caller. If no matching context URI was found, NULL is returned.

Definition at line 63 of file graph.c.

◆ VOLK_graph_copy_contents_txn()

VOLK_rc VOLK_graph_copy_contents_txn	(	void *	txn,
		const VOLK_Graph *	src,
		VOLK_Graph *	dest,
		const VOLK_Term *	s,
		const VOLK_Term *	p,
		const VOLK_Term *	o )

Copy triples from a source graph into a destination one.

The destination graph is not initialized here, so the copy is cumulative.

A 3-term pattern may be provided to filter triples to be extracted from the source graph. If all terms are NULL, all triples are copied.

Parameters

[in]	txn	Transaction handle. It may be NULL, or an open transaction handle, in which case the copy is done within the specified transaction.
[in]	src	Source graph.
[in]	dest	Destination graph.
[in]	s,p,o	Terms to look up for filtering. Any and all terms can be NULL, which indicate unbound terms.

Returns: VOLK_OK on success; VOLK_NOACTION if no triples were copied; <0 if an error occurred.

Definition at line 480 of file graph.c.

◆ VOLK_graph_bool_op_txn()

VOLK_rc VOLK_graph_bool_op_txn	(	void *	txn,
		const VOLK_bool_op	op,
		const VOLK_Graph *	gr1,
		const VOLK_Graph *	gr2,
		VOLK_Graph *	res )

Perform a boolean operation between two graphs.

This method populates an initialized graph with the result of the operation between two other graphs. The resulting graph may be of any store type and may be the result of graphs of different store types.

Parameters

[in]	txn	R/W transaction handle for the destination store. It may be NULL, or an open transaction within which the operation is performed.
[in]	op	Operation to perform. One of VOLK_bool_op.
[in]	gr1	First operand.
[in]	gr2	Second operand.
[out]	res	Result graph. The handle should be initialized via VOLK_graph_new() or equivalent. Any preexisting contents are not removed. If an unrecoverable error occurs, this graph is freed, and any preexisting triples are lost. Therefore, reusing a result graph handle should only be done in tightly controlled loops or sequences.

Returns: VOLK_OK on success; <0 on error.

Definition at line 100 of file graph.c.

◆ VOLK_graph_free()

void VOLK_graph_free ( VOLK_Graph * gr )

Free a graph.

Definition at line 246 of file graph.c.

◆ VOLK_graph_equals()

bool VOLK_graph_equals	(	const VOLK_Graph *	gr1,
		const VOLK_Graph *	gr2 )

Compare two graphs.

Note that if any of the two graphs has an open transaction, the function is performed in the first graph's transaction.

Parameters

[in]	gr1	First operand.
[in]	gr2	Second operand.

Returns: True if the graphs are topologically equal, false otherwise.

Definition at line 330 of file graph.c.

◆ VOLK_graph_uri()

const VOLK_Term * VOLK_graph_uri ( const VOLK_Graph * gr )

Read-only graph URI.

Note that, while VOLK_graph_new() and VOLK_graph_set_uri() expect a string, this function returns the complete VOLK_Term structure.

To change the graph URI, use VOLK_graph_set_uri.

Definition at line 263 of file graph.c.

◆ VOLK_graph_store()

VOLK_Store * VOLK_graph_store ( const VOLK_Graph * gr )

Underlying graph store handle.

Definition at line 267 of file graph.c.

◆ VOLK_graph_set_uri()

VOLK_rc VOLK_graph_set_uri	(	VOLK_Graph *	gr,
		const char *	uri_str )

Set the URI of a graph.

Note that by changing the URI of a graph backed by a context-sensitive store (i.e. VOLK_STORE_MDB*) effectively changes the underlying context that the triples are bound to. Triples are looked up in, and added to, the context that the graph URI represents. A non-context graph retains the same triple set when a graph URI changes, and relative URI lookups are resolved in real-time against the current graph URI.

Parameters

[in]	gr	Graph handle.
[in]	uri_str	New URI string. If namespace-prefixed, it will be resolved according to the graph's namespace map.

Returns: VOLK_OK on success; <0 on error.

Definition at line 272 of file graph.c.

◆ VOLK_graph_size()

size_t VOLK_graph_size ( const VOLK_Graph * gr )

Number of triples in a graph.

Parameters

gr	Graph handle.

Returns: Number of triples, or a negative value on error.

Extern inline definitions.

Definition at line 311 of file graph.c.

◆ VOLK_graph_contains()

bool VOLK_graph_contains	(	const VOLK_Graph *	gr,
		const VOLK_Triple *	spo )

Whether a graph contains a triple.

Parameters

[in]	gr	Graph to look up into.
[in]	spo	Triple to look up.

Returns: 1 if the triple is found, 0 if not found.

Definition at line 654 of file graph.c.

◆ VOLK_graph_add_init_txn()

VOLK_GraphIterator * VOLK_graph_add_init_txn	(	void *	txn,
		VOLK_Graph *	gr )

Initialize an iterator to add triples.

Parameters

[in]	txn	Transaction handle. It may be NULL. If not NULL, its handle will be bound to the iterator handle for its whole life cycle.
[in]	gr	Graph to add to. It is added to the iterator state.

Returns: Iterator handle. This should be passed to VOLK_graph_add_iter() and must be freed with VOLK_graph_iter_free().

Definition at line 343 of file graph.c.

◆ VOLK_graph_add_iter()

VOLK_rc VOLK_graph_add_iter	(	VOLK_GraphIterator *	it,
