FlowOfRdfNodesInDatasetsOps

public FlowOfRdfNodesInDatasetsOps()

Method Details

naturalResources

public static io.reactivex.rxjava3.core.Flowable<ResourceInDataset> naturalResources(org.apache.jena.query.Dataset dataset)

Return a flow over the natural resources in the named graphs of a dataset. A natural resource is a node that has has the same name (IRI) as the graph.

Parameters:

dataset -

Returns:

mapToNodesInDataset

public static Function<org.apache.jena.query.Dataset,NodesInDataset> mapToNodesInDataset(org.apache.jena.query.Query nodeSelector)

Operator that marks (graph, node) pairs from a dataset using a SELECT query with two result variables and returns them in a NodesInDataset object.

Parameters:

nodeSelector -

Returns:

groupedResourceInDataset

public static io.reactivex.rxjava3.core.FlowableTransformer<ResourceInDataset,NodesInDataset> groupedResourceInDataset()

Accumulate consecutive ResourceInDataset items which share the same Dataset or underlying DatasetGraph by reference equality into an Entry<Dataset, List>

Returns:

ungroupResourceInDataset

public static List<ResourceInDataset> ungroupResourceInDataset(NodesInDataset grid)

ungrouperResourceInDataset

public static io.reactivex.rxjava3.core.Flowable<ResourceInDataset> ungrouperResourceInDataset(NodesInDataset grid)

Intended to be used with flatMap flow.flatMap(...)

Parameters:

grid -

Returns:

createKeyMapper

public static Function<? super org.apache.jena.rdfconnection.SparqlQueryConnection,org.apache.jena.graph.Node> createKeyMapper(String keyArg,
 Function<? super String,? extends org.apache.jena.query.Query> queryParser,
 org.apache.jena.query.Query fallback)

mergeConsecutiveResourceInDatasets

public static io.reactivex.rxjava3.core.Flowable<NodesInDataset> mergeConsecutiveResourceInDatasets(io.reactivex.rxjava3.core.Flowable<NodesInDataset> in)

createTransformerFromGroupedTransform

public static io.reactivex.rxjava3.core.FlowableTransformer<ResourceInDataset,ResourceInDataset> createTransformerFromGroupedTransform(io.reactivex.rxjava3.core.FlowableTransformer<NodesInDataset,NodesInDataset> innerTransform)

Adapter to create a transformed for ResourceInDataset based on one for NodesInDataset.

Parameters:

innerTransform -

Returns:
