Method Details

create

public static DatasetDescription create(List<String> defaultGraphURIs,
 List<String> namedGraphURIs)

create

public static DatasetDescription create(Query query)

Create a dataset description, given a query. If the query does not have a dataset description, return null.

create

public static DatasetDescription create(Context context)

Create a dataset description, given a context. If the context does not have a dataset description, return null. The context uses the key ARQConstants.sysDatasetDescription.

create

public static DatasetDescription create(Query query,
 Context context)

Create a dataset description, given a query and context. The context overrides the query FROM/FROM NAMED. If neither the context nor query has a dataset description, return null. The context uses the key ARQConstants.sysDatasetDescription.

isEmpty

public boolean isEmpty()

addDefaultGraphURI

public void addDefaultGraphURI(String uri)

addAllDefaultGraphURIs

public void addAllDefaultGraphURIs(Collection<String> uris)

addNamedGraphURI

public void addNamedGraphURI(String uri)

addAllNamedGraphURIs

public void addAllNamedGraphURIs(Collection<String> uris)

getDefaultGraphURIs

public List<String> getDefaultGraphURIs()

getNamedGraphURIs

public List<String> getNamedGraphURIs()

eachDefaultGraphURI

public Iterator<String> eachDefaultGraphURI()

eachNamedGraphURI

public Iterator<String> eachNamedGraphURI()

createDataset

public Dataset createDataset()

Create a dataset from the description - reads URLs into an in-memory dataset

createDatasetGraph

public DatasetGraph createDatasetGraph()

Create a DatasetGraph from the description - reads URLs into an in-memory DatasetGraph
