Class RDFParser

java.lang.Object

org.apache.jena.riot.RDFParser

public class RDFParser
extends Object

An RDFParser is a process that will generate triples; RDFParserBuilder provides the means to setup the parser.

An RDFParser has a predefined source; the target for output is given when the "parse" method is called. It can be used multiple times in which case the same source is reread. The destination can vary. The application is responsible for concurrency of the destination of the parse operation. The process is

    StreamRDF destination = ...
    RDFParser parser = RDFParser.create().source("filename.ttl").build();
    parser.parse(destination);
 

or using abbreviated forms:

 RDFParser.source("filename.ttl").parse(destination);
 

The destination StreamRDF and can be given as a Graph or DatasetGraph as well.

Method Detail

create

public static RDFParserBuilder create()

Create an RDFParserBuilder.

Often used in a pattern such as:

    RDFParser.create()
        .source("data.ttl")
        .parse(graph);
 

source

public static RDFParserBuilder source(Path path)

Create an RDFParserBuilder and set the source to the Path.

This is a shortcut for RDFParser.create().source(path).

Parameters:

path -

Returns:

this

source

public static RDFParserBuilder source(String uriOrFile)

Create an RDFParserBuilder and set the source to the URI, which can be a filename.

This is a shortcut for RDFParser.create().source(uriOrFile).

Parameters:

uriOrFile -

Returns:

this

fromString

public static RDFParserBuilder fromString(String string)

Create an RDFParserBuilder and set content to parse to be the given string. The syntax must be set with .lang(...).

Shortcut for RDFParser.create.fromString(string).

Parameters:

string -

Returns:

this

source

public static RDFParserBuilder source(InputStream input)

Create an RDFParserBuilder and set the source to InputStream. The InputStream will be closed when the parser is called and the parser can not be reused. The syntax must be set with .lang(...).

This is a shortcut for RDFParser.create().source(input).

Parameters:

input -

Returns:

this

parse

public void parse(StreamRDF destination)
