Interface NamedGraphSetReader

All Known Implementing Classes:

TriGReader, TriXReader, TriXReaderWithExtensions

public interface NamedGraphSetReader

Reads a serialized set of Named Graphs from a Reader, InputStream, or URL into a NamedGraphSet. An Implementation will provide support for a single serialization syntax, such as TriX or TriG.

A NamedGraphSetReader instance can only be used to read one file. To read another file, a new instance must be created.

NamedGraphSetReaders are used through NamedGraphSet's read methods, or through a GraphReaderService.

Method Summary

void	read(NamedGraphSet namedGraphSet, InputStream source, String baseURI, String defaultGraphName) Reads Named Graphs from an InputStream into a NamedGraphSet.
void	read(NamedGraphSet namedGraphSet, Reader source, String baseURI, String defaultGraphName) Reads Named Graphs from a Reader into a NamedGraphSet.

Method Detail

read

void read(NamedGraphSet namedGraphSet,
          Reader source,
          String baseURI,
          String defaultGraphName)

Reads Named Graphs from a Reader into a NamedGraphSet. If some of the graph names from the source are already used in the NamedGraphSet, then the statements from the old graphs will be replaced by those from the source.

Parameters:

namedGraphSet - Graphs read from the source will be stored into this NamedGraphSet

source - The source of the input serialization

baseURI - The URI from where the input was read

defaultGraphName - If a graph in the input has no name attached, then this will be used. When in doubt, use the baseURI.
