    pub ontology_graph: Option<Graph>,
}

A GraphConnection is a wrapper around a DataStoreConnection with a specific Graph and an optional ontology Graph.

Fields

data_store_connection: Arc<DataStoreConnection>

started_at: Instant

graph: Graph

ontology_graph: Option<Graph>

Implementations

impl GraphConnection

pub fn new( data_store_connection: Arc<DataStoreConnection>, graph: Graph, ontology_graph: Option<Graph> ) -> Arc<Self>

pub fn with_data_store_connection( &self, data_store_connection: &Arc<DataStoreConnection> ) -> Arc<Self>

Create a clone with another DataStoreConnection

pub fn import_data_from_file<P>(&self, file: P) -> Result<(), RDFStoreError>where P: AsRef<Path>,

pub fn import_axioms(&self) -> Result<(), RDFStoreError>

pub fn import_rdf_from_directory( &self, root: &Path ) -> Result<u16, RDFStoreError>

Read all RDF files (currently it supports .ttl and .nt files) from the given directory, applying ignore files like .gitignore.

Returns the number of loaded files.

TODO: Support all the types that RDFox supports (and more) TODO: Support ‘*.gz’ files TODO: Parallelize appropriately in sync with number of threads that RDFox uses

pub fn get_triples_count( &self, tx: &Arc<Transaction>, fact_domain: FactDomain ) -> Result<usize, RDFStoreError>

Get the number of triples using the given transaction.

TODO: Implement this with SPARQL COUNT (and compare performance)
