Class ResourceInDatasetFlowOps

java.lang.Object

org.aksw.jena_sparql_api.rx.dataset.ResourceInDatasetFlowOps

public class ResourceInDatasetFlowOps
extends Object

This class provides operators to map between individual objects and flowables of Datasets, ResourceInDataset and NodesInDataset types. Dataset is a set of quads. ResourceInDataset is an abstraction providing Jena's convenient Resource API to a specific resource in one specific model of the dataset's ones. A change to that resource does not affect resources with the same blank node / uri label in another model. NodesInDataset is used for efficiency in operators as it prevents duplicate processing of datasets from which many ResourceInDataset instances are created.
