Module org.apache.jena.arq

Package org.apache.jena.riot.thrift

Class ThriftConvert

java.lang.Object

org.apache.jena.riot.thrift.ThriftConvert

public class ThriftConvert
extends Object

Convert to and from Thrift wire objects. See StreamRDF2Thrift and Thrift2StreamRDF for ways to convert as streams (they recycle intermediate objects).

Many operations have available with a cache. The cache is used for creating URis from strings. It interns the node leading to significant savings of space, especially in the property position.

Method Details

toThriftValue

public static boolean toThriftValue(org.apache.jena.graph.Node node,
 RDF_Term term)

Attempt to encode a node by value (integer, decimal, double) into an RDF_term.

Parameters:

node -

term -

Returns:

true if the term was set, else false.

toThrift

 RDF_Term term)

Encode a Node into an RDF_Term, using values (integer, decimal, double) if possible.

toThrift

public static void toThrift(org.apache.jena.graph.Node node,
 RDF_Term term,
 boolean allowValues)

Encode a Node into an RDF_Term. Control whether to use values (integer, decimal, double) if possible.

toThrift

public static void toThrift(org.apache.jena.graph.Node node,
 PrefixMap pmap,
 RDF_Term term,
 boolean allowValues)

Encode a Node into an RDF_Term

convert

public static org.apache.jena.graph.Node convert(RDF_Term term)

Build a Node from an RDF_Term.

convert

public static org.apache.jena.graph.Node convert(org.apache.jena.atlas.lib.Cache<String,org.apache.jena.graph.Node> uriCache,
 RDF_Term term)
