Examples of org.openrdf.repository.Repository

org.openrdf.repository.Repository
A Sesame repository that contains RDF data that can be queried and updated. Access to the repository can be acquired by openening a connection to it. This connection can then be used to query and/or update the contents of the repository. Depending on the implementation of the repository, it may or may not support multiple concurrent connections.
Please note that a repository needs to be initialized before it can be used and that it should be shut down before it is discarded/garbage collected. Forgetting the latter can result in loss of data (depending on the Repository implementation)! @author Arjohn Kampman
