All Implemented Interfaces:

org.openrdf.rio.RDFParser

public class BigdataTurtleParser
extends org.openrdf.rio.turtle.TurtleParser

RDF parser for Turtle files. This parser is not thread-safe, therefore its public methods are synchronized.

This implementation is based on the 2006/01/02 version of the Turtle specification, with slight deviations:

• Normalization of integer, floating point and boolean values is dependent on the specified datatype handling. According to the specification, integers and booleans should be normalized, but floats don't.
• Comments can be used anywhere in the document, and extend to the end of the line. The Turtle grammar doesn't allow comments to be used inside triple constructs that extend over multiple lines, but the author's own parser deviates from this too.

Method Detail

parseValue

protected org.openrdf.model.Value parseValue()
                                      throws IOException,
                                             org.openrdf.rio.RDFParseException

Parses an RDF value. This method parses uriref, qname, node ID, quoted literal, integer, double and boolean.

Overrides:

parseValue in class org.openrdf.rio.turtle.TurtleParser

Throws:

IOException

org.openrdf.rio.RDFParseException

parseURIOrSid

protected org.openrdf.model.Value parseURIOrSid()
                                         throws IOException,
                                                org.openrdf.rio.RDFParseException

Throws:

IOException

org.openrdf.rio.RDFParseException

parseSid

protected org.openrdf.model.Value parseSid()
                                    throws IOException,
                                           org.openrdf.rio.RDFParseException

Throws:

IOException

org.openrdf.rio.RDFParseException

skipWS

protected int skipWS()
              throws IOException

Consumes any white space characters (space, tab, line feed, newline) and comments (#-style) from reader. After this method has been called, the first character that is returned by reader is either a non-ignorable character, or EOF. For convenience, this character is also returned by this method.

Returns:

The next character that will be returned by reader.

Throws:

IOException

parseNodeID

protected org.openrdf.model.BNode parseNodeID()
                                       throws IOException,
                                              org.openrdf.rio.RDFParseException

Parses a blank node ID, e.g. _:node1.

Overrides:

parseNodeID in class org.openrdf.rio.turtle.TurtleParser

Throws:

IOException

org.openrdf.rio.RDFParseException
