getConnection

public org.openrdf.sail.inferencer.fc.ForwardChainingRDFSInferencerConnection getConnection()
                                                                                     throws SailException

Description copied from interface: Sail

Opens a connection on the Sail which can be used to query and update data. Depending on how the implementation handles concurrent access, a call to this method might block when there is another open connection on this Sail.

Specified by:

getConnection in interface NotifyingSail

Specified by:

getConnection in interface Sail

Overrides:

getConnection in class NotifyingSailWrapper

Throws:

SailException - If no transaction could be started, for example because the Sail is not writable.

initialize

public void initialize()
                throws SailException

Adds axiom statements to the underlying Sail.

Specified by:

initialize in interface Sail

Overrides:

initialize in class SailWrapper

Throws:

SailException - If the Sail could not be initialized.
