Method Detail

read

public void read(Model model,
                 InputStream in,
                 String base)

Description copied from interface: RDFReader

Read serialized RDF from an InputStream and add the statements to a Model.

Specified by:

read in interface RDFReader

Parameters:

model - The model to which statements are added.

in - The InputStream from which to read

base - The base to use when converting relative to absolute URI's. The base URI may be null if there are no relative URIs to convert. A base URI of "" may permit relative URIs to be used in the model unconverted.

read

public void read(Model model,
                 Reader reader,
                 String base)

Description copied from interface: RDFReader

It is usually a mistake to use this method. Read serialized RDF from a Reader and add the statements to a Model. It is generally better to use an InputStream if possible. RDFReader.read(Model,InputStream,String), otherwise there is a danger of a mismatch between the character encoding of say the FileReader and the character encoding of the data in the file.

Specified by:

read in interface RDFReader

Parameters:

model - The model to which statements are added.

reader - the reader from which to read

base - The base to use when converting relative to absolute URI's. The base URI may be null if there are no relative URIs to convert. A base URI of "" may permit relative URIs to be used in the model unconverted.

read

public void read(Model model,
                 String url)

Description copied from interface: RDFReader

Read serialized RDF from a url and add the statements to a model.

Specified by:

read in interface RDFReader

Parameters:

model - the model to which statements should be added

url - the url, as a string, from which the serialized RDF should be read.

setProperty

public Object setProperty(String propName,
                          Object propValue)

Description copied from interface: RDFReader

Set the value of a reader property.

The behaviour of a reader may be influenced by setting property values. The properties and there effects may depend on the individual reader implementation.

An RDFReader's behaviour can be influenced by defining property values interpreted by that particular reader class. The values for such properties can be changed by calling this method.

No standard properties are defined. For the properties recognised by any particular reader implementation, see the documentation for that implementation.

The built-in RDFReaders have properties as defined by:

N3

N-TRIPLE

No properties.

RDF/XML

RDF/XML-ABBREV

See JenaReader.setProperty(String,Object)

Specified by:

setProperty in interface RDFReader

Parameters:

propName - the name of the property

propValue - the value of the property

Returns:

the previous value of the property, or null if there wasn't one

setErrorHandler

public RDFErrorHandler setErrorHandler(RDFErrorHandler errHandler)

Description copied from interface: RDFReader

Set an error handler for the reader

Specified by:

setErrorHandler in interface RDFReader

Parameters:

errHandler - the new error handler

Returns:

the previous error handler

readResource

public Resource readResource()

readNode

public RDFNode readNode()
