All Implemented Interfaces:

LoaderInterface

public class NTReader

extends java.lang.Object

implements LoaderInterface

This is a very very basic Ntriples parser with no datatyping or language 
support.

It will try and read Ntriples document in and interpret it as a query or
an RDF file depending on which method is called.

Because it's here, theoretically you can use Tinkling on its own without 
any external classes; however you would probably be better off using RIO 
or ARP.

The N3Reader.java class uses Jena's N3 parser and code by Andy Seaborne, 
which returns Ntriples; therefore this class is also used there.

GraphInterface	loadGraph(java.lang.String fn) LoaderInterface function
GraphInterface	loadGraph(java.lang.String url, GraphInterface rdf) LoaderInterface function
ComplexQuery	parseStringToQuery(java.lang.String string) Converts a String to an Ntriples query, where the string contains multiple ntriples lines.
Graph	parseStringToStatement(java.lang.String string) read in an Ntriples Stringand return a Graph
Graph	parseStringToStatement(java.lang.String string, GraphInterface gr) read in an Ntriples text file by filename and return the Graph passed to it
ComplexQuery	parseToQuery(java.lang.String fn) Read in an Ntriples text file and return a ComplexQuery for more details see the RDF Query test work: http://www.w3.org/2003/03/rdfqr-tests/ An ntriples file can (unofficially and experimentally) be interpreted as a query, with bnodes representing variables.
Graph	parseToStatement(java.lang.String fn) Read in an Ntriples text file by filename and return a Graph
Graph	parseToStatement(java.lang.String fn, GraphInterface gr) read in an Ntriples text file by filename and return a Graph
Query	processTripleToQuery(java.lang.String part) Nasty Ntriples parser, returning a Query given a String (assumed to be a single line of NTriples)

Method Detail

loadGraph

public GraphInterface loadGraph(java.lang.String fn)

LoaderInterface function

Specified by:

loadGraph in interface LoaderInterface

loadGraph

public GraphInterface loadGraph(java.lang.String url,
                                GraphInterface rdf)

LoaderInterface function

Specified by:

loadGraph in interface LoaderInterface

parseToQuery

public ComplexQuery parseToQuery(java.lang.String fn)

Read in an Ntriples text file and return a ComplexQuery for more details see the RDF Query test work: http://www.w3.org/2003/03/rdfqr-tests/ An ntriples file can (unofficially and experimentally) be interpreted as a query, with bnodes representing variables. Predicates can also be blank/varianbles under this interpretation.

parseStringToQuery

public ComplexQuery parseStringToQuery(java.lang.String string)

Converts a String to an Ntriples query, where the string contains multiple ntriples lines.

processTripleToQuery

public Query processTripleToQuery(java.lang.String part)

Nasty Ntriples parser, returning a Query given a String (assumed to be a single line of NTriples)

parseToStatement

public Graph parseToStatement(java.lang.String fn)

Read in an Ntriples text file by filename and return a Graph

parseToStatement

public Graph parseToStatement(java.lang.String fn,
                              GraphInterface gr)

read in an Ntriples text file by filename and return a Graph

parseStringToStatement

public Graph parseStringToStatement(java.lang.String string,
                                    GraphInterface gr)

read in an Ntriples text file by filename and return the Graph passed to it

parseStringToStatement

public Graph parseStringToStatement(java.lang.String string)

read in an Ntriples Stringand return a Graph
