Constructor Detail

TriXParser

public TriXParser()

Creates a new TriXParser that will use a SimpleValueFactory to create objects for resources, bNodes, literals and statements.

TriXParser

public TriXParser(ValueFactory valueFactory)

Creates a new TriXParser that will use the supplied ValueFactory to create objects for resources, bNodes, literals and statements.

Parameters:

valueFactory - A ValueFactory.

Method Detail

getRDFFormat

public final RDFFormat getRDFFormat()

Description copied from interface: RDFParser

Gets the RDF format that this parser can parse.

Specified by:

getRDFFormat in interface RDFParser

getSupportedSettings

public Collection<RioSetting<?>> getSupportedSettings()

Specified by:

getSupportedSettings in interface RDFParser

Overrides:

getSupportedSettings in class AbstractRDFParser

Returns:

A collection of RioSettings that are supported by this RDFParser.

parse

public void parse(InputStream in,
                  String baseURI)
           throws IOException,
                  RDFParseException,
                  RDFHandlerException

Parses the data from the supplied InputStream, using the supplied baseURI to resolve any relative URI references.

Specified by:

parse in interface RDFParser

Parameters:

in - The InputStream from which to read the data, must not be null.

baseURI - The URI associated with the data in the InputStream, must not be null.

Throws:

IOException - If an I/O error occurred while data was read from the InputStream.

RDFParseException - If the parser has found an unrecoverable parse error.

RDFHandlerException - If the configured statement handler encountered an unrecoverable error.

IllegalArgumentException - If the supplied input stream or base URI is null.

parse

public void parse(Reader reader,
                  String baseURI)
           throws IOException,
                  RDFParseException,
                  RDFHandlerException

Parses the data from the supplied Reader, using the supplied baseURI to resolve any relative URI references.

Specified by:

parse in interface RDFParser

Parameters:

reader - The Reader from which to read the data, must not be null.

baseURI - The URI associated with the data in the InputStream, must not be null.

Throws:

IOException - If an I/O error occurred while data was read from the InputStream.

RDFParseException - If the parser has found an unrecoverable parse error.

RDFHandlerException - If the configured statement handler has encountered an unrecoverable error.

IllegalArgumentException - If the supplied reader or base URI is null.

createLiteral

protected Literal createLiteral(String label,
                                String lang,
                                IRI datatype)
                         throws RDFParseException

Description copied from class: AbstractRDFParser

Creates a Literal object with the supplied parameters.

Overrides:

createLiteral in class AbstractRDFParser

Throws:

RDFParseException

reportWarning

protected void reportWarning(String msg)

Overrides AbstractRDFParser.reportWarning(String), adding line- and column number information to the error.

Overrides:

reportWarning in class AbstractRDFParser

reportError

protected void reportError(String msg,
                           RioSetting<Boolean> setting)
                    throws RDFParseException

Overrides AbstractRDFParser.reportError(String, RioSetting), adding line- and column number information to the error.

Overrides:

reportError in class AbstractRDFParser

Parameters:

msg - The message to use for ParseErrorListener.error(String, long, long) and for RDFParseException.RDFParseException(String, long, long) .

setting - The boolean setting that will be checked to determine if this is an issue that we need to look at at all. If this setting is true, then the error listener will receive the error, and if ParserConfig.isNonFatalError(RioSetting) returns true an exception will be thrown.

Throws:

RDFParseException - If RioConfig.get(RioSetting) returns true, and ParserConfig.isNonFatalError(RioSetting) returns true for the given setting.

reportFatalError
