Method Detail

parseNIF

public List<Document> parseNIF(String nifString)

Description copied from interface: NIFParser

Parses the NIF data inside the given String and returns the list of documents that could be found.

Specified by:

parseNIF in interface NIFParser

Parameters:

nifString - a String containing the NIF data

Returns:

a list of Document instances found in the given NIF

parseNIF

public List<Document> parseNIF(String nifString,
                               org.apache.jena.rdf.model.Model model)

Description copied from interface: NIFParser

Like NIFParser.parseNIF(String), this method parses the NIF data inside the given String and returns the list of documents that could be found. But it uses the given model to store this information.

Note that the parser will use and change the data that is already inside the given model.

The aim of this method is to take a reference to a model (that might be empty) and store all additional information that has been read but could not be added to the created Document instances.

Specified by:

parseNIF in interface NIFParser

Parameters:

nifString - a String containing the NIF data

model - a model which is used to store the NIF data

Returns:

a list of Document instances found in the given NIF

parseNIF

public List<Document> parseNIF(Reader reader)

Description copied from interface: NIFParser

Parses the NIF data read from the given Reader and returns the list of documents that could be found.

Note that following the recommendations of the Jena framework we highly recommend to use NIFParser.parseNIF(InputStream) instead of using a Reader since the InputStream is not relying on a specific encoding.

Specified by:

parseNIF in interface NIFParser

Parameters:

reader - a Reader from which the NIF data is read

Returns:

a list of Document instances found in the given NIF

parseNIF

public List<Document> parseNIF(Reader reader,
                               org.apache.jena.rdf.model.Model nifModel)

Description copied from interface: NIFParser

Like NIFParser.parseNIF(Reader), this method parses the NIF data inside the given String and returns the list of documents that could be found. But it uses the given model to store this information.

Note that following the recommendations of the Jena framework we highly recommend to use NIFParser.parseNIF(InputStream, Model) instead of using a Reader since the InputStream is not relying on a specific encoding.

Note that the parser will use and change the data that is already inside the given model.

The aim of this method is to take a reference to a model (that might be empty) and store all additional information that has been read but could not be added to the created Document instances.

Specified by:

parseNIF in interface NIFParser

Parameters:

reader - a Reader from which the NIF data is read

nifModel - a model which is used to store the NIF data

Returns:

a list of Document instances found in the given NIF

parseNIFModel

protected abstract org.apache.jena.rdf.model.Model parseNIFModel(Reader reader,
                                                                 org.apache.jena.rdf.model.Model nifModel)

parseNIF

public List<Document> parseNIF(InputStream is)

Description copied from interface: NIFParser

Parses the NIF data read from the given InputStream and returns the list of documents that could be found.

Specified by:

parseNIF in interface NIFParser

Parameters:

is - an InputStream from which the NIF data is read

Returns:

a list of Document instances found in the given NIF

parseNIF

public List<Document> parseNIF(InputStream is,
                               org.apache.jena.rdf.model.Model nifModel)

Description copied from interface: NIFParser

Like NIFParser.parseNIF(InputStream), this method parses the NIF data inside the given String and returns the list of documents that could be found. But it uses the given model to store this information.

Note that the parser will use and change the data that is already inside the given model.

The aim of this method is to take a reference to a model (that might be empty) and store all additional information that has been read but could not be added to the created Document instances.

Specified by:

parseNIF in interface NIFParser

Parameters:

is - an InputStream from which the NIF data is read

nifModel - a model which is used to store the NIF data

Returns:

a list of Document instances found in the given NIF

parseNIFModel

protected abstract org.apache.jena.rdf.model.Model parseNIFModel(InputStream is,
                                                                 org.apache.jena.rdf.model.Model nifModel)

getHttpContentType

public String getHttpContentType()

Description copied from interface: NIFParser

This method should return the HTTP content type string for the data that can be handled by this reader.

Specified by:

getHttpContentType in interface NIFParser

Returns:

the HTTP content type string

infereTypes

protected void infereTypes(org.apache.jena.rdf.model.Model nifModel)

getDefaultModel

protected org.apache.jena.rdf.model.Model getDefaultModel()
