Member Function Documentation

◆ connect()

knowCore::ReturnVoid Connection::connect ( bool _initialise_database = false )

Attempt to connect to the server

Returns: false if connection fails, or if it is already connected

◆ connectionUuid()

QUuid Connection::connectionUuid ( ) const

Returns: the UUID to the connection

◆ createExtensionObject()

template<typename _T_ >

void kDB::Repository::Connection::createExtensionObject ( )

Register an extension object with this connection. Connection take ownership of the object. The object is deleted upon disconnection and should hold a knowCore::WeakReference<Connection> to avoid circular reference.

This function is intended to be use by an initaĺisation function of an extension.

◆ createSPARQLQuery()

knowDBC::Query Connection::createSPARQLQuery	(	const RDFEnvironment &	_environment = RDFEnvironment(),
		const QString &	_query = QString(),
		const knowCore::ValueHash &	_bindings = knowCore::ValueHash(),
		const knowCore::ValueHash &	_options = knowCore::ValueHash() ) const

Create an SPARQL query for this connection

◆ createSQLQuery()

knowDBC::Query Connection::createSQLQuery	(	const QString &	_query = QString(),
		const knowCore::ValueHash &	_bindings = knowCore::ValueHash(),
		const knowCore::ValueHash &	_options = knowCore::ValueHash() ) const

Create an SQL query for this connection

◆ disconnect()

void Connection::disconnect ( )

Disconnect this connection from the server (this propagage to all the copy of this object!)

◆ enableExtension()

knowCore::ReturnVoid Connection::enableExtension ( const QString & _extension )

Enable an extension

Returns: true if extension is successfully enabled

◆ executeConnection()

QUuid Connection::executeConnection ( const std::function< void(const Connection &)> & _function ) const

Called a function after connection is completed.

◆ executeDisconnection()

QUuid Connection::executeDisconnection ( const std::function< void()> & _function ) const

Called a function when disconnected (warning, cannot use connection as disconnection can occurs during deletion, and should not hold a reference to connection to avoid leaks).

◆ extensionObject()

template<typename _T_ >

_T_ * kDB::Repository::Connection::extensionObject ( ) const

Returns: the extension object associated with this connection

◆ isConnected()

bool Connection::isConnected ( ) const

Returns: true if connected to the server

◆ isExtensionEnabled()

bool Connection::isExtensionEnabled ( const QString & _extension ) const

Enable an extension

Returns: true if an extension is enabled

◆ isValid()

bool Connection::isValid ( ) const

Returns: true if this is a valid connection (ie created with create for instance Connection().isValid() return false)

◆ krQueryEngine()

krQuery::Engine * Connection::krQueryEngine ( ) const

Returns: the query engine associated with this connection.

◆ oid()

quint64 Connection::oid ( const QString & _type ) const

Returns: the postgresql Oid type associated with the _type

◆ rsaAlgorithm()

Cyqlops::Crypto::RSAAlgorithm Connection::rsaAlgorithm ( ) const

This function gives access to the RSA key used by the server for signing.

◆ serverUri()

knowCore::Uri Connection::serverUri ( ) const

Returns: a URI uniquely identifying this server (based on the UUID)
