Dataset (Stardog-9.0.0 API)

All Known Implementing Classes:

Datasets.DatasetImpl
```
public interface Dataset
```
Amalgum of an RDF 1.1 Dataset, a SPARQL 1.1 RDF Dataset & a SPARQL 1.1 update [graph](https://www.w3.org/TR/sparql11-update/#deleteInsert)

Both RDF 1.1 and SPARQL specify that there is a single default graph per Dataset. However, with SPARQL 1.1 you can specify multiple graphs and the single default graph is presumed to be the RDF merge of the specified graphs

This Dataset representation takes the RDF 1.1 position wrt to graph names; both bnodes and IRIs are legal identifiers.

Method Summary

All Methods Instance Methods Abstract Methods Default Methods
Modifier and Type	Method	Description
`com.google.common.collect.ImmutableSet<Resource>`	`defaultGraphs()`	The set of graphs, the union of which, makes up the default component of the active graph
`java.util.Optional<Resource>`	`defaultInsertGraph()`	Optionally, the graph where write queries should insert data.
`com.google.common.collect.ImmutableSet<Resource>`	`defaultRemoveGraphs()`	The set of graphs write queries can remove data from.
`default boolean`	`isEmpty()`
`com.google.common.collect.ImmutableSet<Resource>`	`namedGraphs()`	The set of named graphs that are a part of the active graph of the dataset.

- Method Detail
  - isEmpty
```
default boolean isEmpty()

  - defaultRemoveGraphs
```
@Nonnull
com.google.common.collect.ImmutableSet<Resource> defaultRemoveGraphs()
```
    The set of graphs write queries can remove data from.
    
    Returns:
    
    the graphs
  - defaultInsertGraph
```
@Nonnull
java.util.Optional<Resource> defaultInsertGraph()
```
    Optionally, the graph where write queries should insert data.
    
    Returns:
    
    the graph to insert into
  - defaultGraphs
```
@Nonnull
com.google.common.collect.ImmutableSet<Resource> defaultGraphs()
```
    The set of graphs, the union of which, makes up the default component of the active graph
    
    Returns:
    
    the default graphs; when empty, the default graph of the database is used
  - namedGraphs
```
@Nonnull
com.google.common.collect.ImmutableSet<Resource> namedGraphs()
```
    The set of named graphs that are a part of the active graph of the dataset.
    
    Returns:
    
    the named graphs
