Interface RDFReader

All Known Implementing Classes:

JenaReader

public interface RDFReader

An RDFReader reads a serialized represenation of RDF, e.g. RDF/XML, n-triple or n3 and adds the statements to a model.

Method Summary

Methods

Modifier and Type	Method and Description
void	read(Model model, InputStream r, String base) Read serialized RDF from an InputStream and add the statements to a Model.
void	read(Model model, Reader r, String base) It is usually a mistake to use this method.
void	read(Model model, String url) Read serialized RDF from a url and add the statements to a model.
RDFErrorHandler	setErrorHandler(RDFErrorHandler errHandler) Set an error handler for the reader
Object	setProperty(String propName, Object propValue) Set the value of a reader property.

Method Detail

read

void read(Model model,
        Reader r,
        String base)

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. 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.

Parameters:

model - The model to which statements are added.

r - 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

void read(Model model,
        InputStream r,
        String base)

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

Parameters:

model - The model to which statements are added.

r - 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

void read(Model model,
        String url)

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

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

Object setProperty(String propName,
                 Object propValue)

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 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)

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

RDFErrorHandler setErrorHandler(RDFErrorHandler errHandler)

Set an error handler for the reader

Parameters:

errHandler - the new error handler

Returns:

the previous error handler
