RDFaExtractor

@Deprecated
public RDFaExtractor(boolean verifyDataType,
                     boolean stopAtFirstError)

Deprecated.

since 2.4. This extractor has never supported these settings. Use RDFaExtractor() instead.

Parameters:

verifyDataType - has no effect

stopAtFirstError - has no effect

RDFaExtractor

public RDFaExtractor()

Method Detail

setStopAtFirstError

@Deprecated
public void setStopAtFirstError(boolean stopAtFirstError)

Deprecated.

since 2.4. This extractor has never supported this setting. Do not use.

Description copied from interface: Extractor.ContentExtractor

If true, the extractor will stop at first parsing error, iffalse the extractor will attempt to ignore all parsing errors.

Specified by:

setStopAtFirstError in interface Extractor.ContentExtractor

Overrides:

setStopAtFirstError in class BaseRDFExtractor

Parameters:

stopAtFirstError - has no effect

setVerifyDataType

@Deprecated
public void setVerifyDataType(boolean verifyDataType)

Deprecated.

since 2.4. This extractor has never supported this setting. Do not use.

Overrides:

setVerifyDataType in class BaseRDFExtractor

Parameters:

verifyDataType - has no effect

getDescription

public ExtractorDescription getDescription()

Description copied from interface: Extractor

Returns a ExtractorDescription of this extractor.

Returns:

the object representing the extractor description.

getParser

@Deprecated
protected org.eclipse.rdf4j.rio.RDFParser getParser(ExtractionContext extractionContext,
                                                    ExtractionResult extractionResult)

Deprecated.

since 2.4. This extractor no longer wraps an RDF4J RDFParser. Do not use this method.

Specified by:

getParser in class BaseRDFExtractor

Parameters:

extractionContext - the extraction context

extractionResult - the extraction result

Returns:

a RDFParser

run

public void run(ExtractionParameters extractionParameters,
                ExtractionContext extractionContext,
                InputStream in,
                ExtractionResult extractionResult)
         throws IOException,
                ExtractionException

Description copied from interface: Extractor

Executes the extractor. Will be invoked only once, extractors are not reusable.

Specified by:

run in interface Extractor<InputStream>

Overrides:

run in class BaseRDFExtractor

Parameters:

extractionParameters - the parameters to be applied during the extraction.

extractionContext - The document context.

in - The extractor input data.

extractionResult - the collector for the extracted data.

Throws:

IOException - On error while reading from the input stream.

ExtractionException - On other error, such as parse errors.
