Class HTTPRepository

java.lang.Object

org.eclipse.rdf4j.repository.base.AbstractRepository

org.eclipse.rdf4j.repository.http.HTTPRepository

All Implemented Interfaces:

HttpClientDependent, SesameClientDependent, Repository

public class HTTPRepository
extends AbstractRepository
implements HttpClientDependent, SesameClientDependent

A repository that serves as a proxy for a remote repository on a Sesame Server. Methods in this class may throw the specific RepositoryException subclass UnautorizedException, the semantics of which is defined by the HTTP protocol.

This repository proxy uses a Sesame-specific extension of the SPARQL 1.1 Protocol to communicate with the server. For communicating with a non-Sesame-based SPARQL endpoint, it is recommend to use SPARQLRepository instead.

public RepositoryConnection getConnection()
                                   throws RepositoryException

Specified by:

getConnection in interface Repository

Throws:

isWritable

public boolean isWritable()
                   throws RepositoryException

Specified by:

isWritable in interface Repository

Throws:

RepositoryException

setPreferredTupleQueryResultFormat

public void setPreferredTupleQueryResultFormat(TupleQueryResultFormat format)

Sets the preferred serialization format for tuple query results to the supplied TupleQueryResultFormat, overriding the SparqlSession 's default preference. Setting this parameter is not necessary in most cases as the SparqlSession by default indicates a preference for the most compact and efficient format available.

Parameters:

format - the preferred TupleQueryResultFormat. If set to 'null' no explicit preference will be stated.

getPreferredTupleQueryResultFormat

public TupleQueryResultFormat getPreferredTupleQueryResultFormat()

Indicates the current preferred TupleQueryResultFormat.

Returns:

The preferred format, of 'null' if no explicit preference is defined.

setPreferredRDFFormat

public void setPreferredRDFFormat(RDFFormat format)

Sets the preferred serialization format for RDF to the supplied RDFFormat, overriding the SparqlSession's default preference. Setting this parameter is not necessary in most cases as the SparqlSession by default indicates a preference for the most compact and efficient format available.

Use with caution: if set to a format that does not support context serialization any context info contained in the query result will be lost.

Parameters:

format - the preferred RDFFormat. If set to 'null' no explicit preference will be stated.

getPreferredRDFFormat

public RDFFormat getPreferredRDFFormat()

Indicates the current preferred RDFFormat.

Returns:

The preferred format, of 'null' if no explicit preference is defined.

setUsernameAndPassword

public void setUsernameAndPassword(String username,
                                   String password)

Set the username and password to use for authenticating with the remote repository.

Parameters:

username - the username. Setting this to null will disable authentication.

password - the password. Setting this to null will disable authentication.

getRepositoryURL

public String getRepositoryURL()

initializeInternal

protected void initializeInternal()
                           throws RepositoryException

Specified by:

initializeInternal in class AbstractRepository

Throws:

RepositoryException

shutDownInternal

protected void shutDownInternal()
                         throws RepositoryException

Specified by:

shutDownInternal in class AbstractRepository

Throws:

RepositoryException

createHTTPClient

protected SesameSession createHTTPClient()

Creates a new HTTPClient object. Subclasses may override to return a more specific HTTPClient subtype.

Returns:

a HTTPClient object.
