public static java.lang.String RDFXML_FORMAT

Constructor Detail

AllegroGraphModel

public AllegroGraphModel(Graph base)

Create an AllegroGraph model to front an AllegroGraph graph.

AllegroGraphModel

public AllegroGraphModel(Graph base,
                         Personality personality)

Method Detail

version

public static java.lang.String version()

Query the current AllegroGraphModel version.

Returns:

a version string.

getAllegroGraphStore

public AllegroGraph getAllegroGraphStore()

getName

public java.lang.String getName()

toString

public java.lang.String toString()

read

public Model read(java.lang.String url)

read

public Model read(java.io.Reader reader,
                  java.lang.String base)

read

public Model read(java.io.InputStream reader,
                  java.lang.String base)

read

public Model read(java.lang.String url,
                  java.lang.String lang)

read

public Model read(java.lang.String url,
                  java.lang.String base,
                  java.lang.String lang)

Load triples from the source 'url' into the graph/context for this model. If that graph is an INF graph, load into the underlying raw graph instead.

read

public Model read(java.io.Reader reader,
                  java.lang.String base,
                  java.lang.String lang)

read

public Model read(java.io.InputStream reader,
                  java.lang.String base,
                  java.lang.String lang)

supportsTransactions

public boolean supportsTransactions()

removeAll

public Model removeAll()

Remove all the statements from this model.

removeAll

public Model removeAll(Resource s,
                       Property p,
                       RDFNode o)

Remove all the statements matching (s, p, o) from this model.

close

public void close()

There appears to be nothing in AllegroGraph that corresponds a call to close a model, so this call is a no-op. Without it, the Jena code goes into an infinite recursion, so this method really does need to be here.

indexTriples

public void indexTriples(boolean indexAll,
                         boolean asynchronous)

Index the triples in the AllegroGraph store. This should be done after every batch of updates. By default, only triples added after the last call to 'indexTriples' are indexed. If 'indexAll' is set to 'true', all triples in the store are re-indexed. If 'asynchronous' is set to 'true', a separate thread will be created to index the triples, and the call to 'indexTriples' returns immediately (before the indexing has completed).

size

public long size()

Slowly and laboriously count the number of triples in the base graph associated with this model.
