Interface OWLConnection

All Superinterfaces:

All Known Subinterfaces:

All Known Implementing Classes:

DefaultOntopOWLConnection

public interface OWLConnection
extends AutoCloseable

Handler for a connection. Note that as with JDBC, executing queries in parallels over a single connection is inefficient, since JDBC drivers will serialize each query execution and you get a bottle neck (even if using multiple OWLStatement) . Having explicit OWLConnections allows to initialize a single OWLReasoner and make multiple queries in parallel with good performance (as with JDBC).

Besides parallel connections, at the moment, the class is not very useful, it will be when transactions and updates are implemented. Or when we allow the user to setup the kind of statement that he wants to use.
