add
public void add(File file, String baseURI, RDFFormat dataFormat, Resource... contexts) throws IOException, RDFParseException, RepositoryException Description copied from interface:RepositoryConnection
Adds RDF data from the specified file to a specific contexts in the repository.- Specified by:
add
in interfaceRepositoryConnection
- Overrides:
add
in classRepositoryConnectionWrapper
- Parameters:
file
- A file containing RDF data.baseURI
- The base URI to resolve any relative URIs that are in the data against. This defaults to the value offile.toURI()
if the value is set to null.Note that if the data contains an embedded base URI, that embedded base URI will overrule the value supplied here (see RFC 3986 section 5.1 for details).
dataFormat
- The serialization format of the data. If set to null, the format will be automatically determined by examining the file name extension of the supplied File.contexts
- The contexts to add the data to. Note that this parameter is a vararg and as such is optional. If no contexts are specified, the data is added to any context specified in the actual data file, or if the data contains no context, it is added without context. If one or more contexts are specified the data is added to these contexts, ignoring any context information in the data itself.- Throws:
IOException
- If an I/O error occurred while reading from the file.RDFParseException
- If an error was found while parsing the RDF data.RepositoryException
- If the data could not be added to the repository, for example because the repository is not writable.
-
add
public void add(InputStream in, String baseURI, RDFFormat dataFormat, Resource... contexts) throws IOException, RDFParseException, RepositoryException Description copied from interface:RepositoryConnection
Adds RDF data from an InputStream to the repository, optionally to one or more named contexts.- Specified by:
add
in interfaceRepositoryConnection
- Overrides:
add
in classRepositoryConnectionWrapper
- Parameters:
in
- An InputStream from which RDF data can be read.baseURI
- The base URI to resolve any relative URIs that are in the data against. May benull
.Note that if the data contains an embedded base URI, that embedded base URI will overrule the value supplied here (see RFC 3986 section 5.1 for details).
dataFormat
- The serialization format of the data.contexts
- The contexts to add the data to. If one or more contexts are supplied the method ignores contextual information in the actual data. If no contexts are supplied the contextual information in the input stream is used, if no context information is available the data is added without any context.- Throws:
IOException
- If an I/O error occurred while reading from the input stream.RDFParseException
- If an error was found while parsing the RDF data.RepositoryException
- If the data could not be added to the repository, for example because the repository is not writable.
-
add
public void add(Iterable<? extends Statement> statements, Resource... contexts) throws RepositoryException Description copied from interface:RepositoryConnection
Adds the supplied statements to this repository, optionally to one or more named contexts.- Specified by:
add
in interfaceRepositoryConnection
- Overrides:
add
in classRepositoryConnectionWrapper
- Parameters:
statements
- The statements that should be added. In case the iterable isNamespaceAware
and the target repository supports it, the iterable's namespaces are also added to the repository, without overwriting existing ones.contexts
- The contexts to add the statements to. Note that this parameter is a vararg and as such is optional. If no contexts are specified, each statement is added to any context specified in the statement, or if the statement contains no context, it is added without context. If one or more contexts are specified each statement is added to these contexts, ignoring any context information in the statement itself. ignored.- Throws:
RepositoryException
- If the statements could not be added to the repository, for example because the repository is not writable.
-
add

- The contexts to add the statements to. Note that this parameter is a vararg and as such is optional. If no contexts are specified, each statement is added to any context specified in the statement, or if the statement contains no context, it is added without context. If one or more contexts are specified each statement is added to these contexts, ignoring any context information in the statement itself. ignored.- Throws:
RepositoryException
- If the statements could not be added to the repository, for example because the repository is not writable.
-
add
public void add(Reader reader, String baseURI, RDFFormat dataFormat, Resource... contexts) throws IOException, RDFParseException, RepositoryException Description copied from interface:RepositoryConnection
Adds RDF data from a Reader to the repository, optionally to one or more named contexts. Note: using a Reader to upload byte-based data means that you have to be careful not to destroy the data's character encoding by enforcing a default character encoding upon the bytes. If possible, adding such data using an InputStream is to be preferred.- Specified by:
add
in interfaceRepositoryConnection
- Overrides:
add
in classRepositoryConnectionWrapper
- Parameters:
reader

dataFormat
- The serialization format of the data.contexts
- The contexts to add the data to. If one or more contexts are specified the data is added to these contexts, ignoring any context information in the data itself.- Throws:
IOException
- If an I/O error occurred while reading from the reader.RDFParseException
- If an error was found while parsing the RDF data.RepositoryException
- If the data could not be added to the repository, for example because the repository is not writable.
-
add
public void add(Resource subject, IRI predicate, Value object, Resource... contexts) throws RepositoryException Description copied from interface:RepositoryConnection

- The statement's predicate.object
- The statement's object.contexts
- The contexts to add the data to. Note that this parameter is a vararg and as such is optional. If no contexts are specified, the data is added to any context specified in the actual data file, or if the data contains no context, it is added without context. If one or more contexts are specified the data is added to these contexts, ignoring any context information in the data itself.- Throws:
RepositoryException
- If the data could not be added to the repository, for example because the repository is not writable.

dataFormat
- The serialization format of the data. If set to null, the format will be automatically determined by examining the content type in the HTTP response header, and failing that, the file name extension of the supplied URL.contexts
