public class GSP
extends java.lang.Object

Client for the SPARQL 1.1 Graph Store Protocol.

This is extended to include operations GET, POST and PUT on datasets.

Examples:

   // Get the default graph.
   Graph graph = GSP.service("http://example/dataset").defaultGraph().GET();

   // Get a named graph.
   Graph graph = GSP.service("http://example/dataset").namedGraph("http://my/graph").GET();

   // POST (add) to a named graph.
   Graph myData = ...;
   GSP.service("http://example/dataset").namedGraph("http://my/graph").POST(myData);

  - service
```
public static GSP service(java.lang.String service)
```
    Create a request to the remote service (without GSP naming). Call defaultGraph() or graphName(String) to select the target graph.
    
    Parameters:
    
    service -
  - request
```
public static GSP request()
```
    Create a request to the remote service (without GSP naming). Call endpoint(java.lang.String) to set the target. Call defaultGraph() or graphName(String) to select the target graph.
  - endpoint
```
public GSP endpoint(java.lang.String serviceURL)
```
    Set the URL of the query endpoint. This replaces any value set in the service(String) call.
  - httpClient
```
public GSP httpClient(java.net.http.HttpClient httpClient)
```
  - httpHeader
```
public GSP httpHeader(java.lang.String headerName,
                      java.lang.String headerValue)
```
    Set an HTTP header that is added to the request. See accept(org.apache.jena.riot.Lang), acceptHeader(java.lang.String) and contentType(RDFFormat). for specific handling of Accept: and Content-Type.
  - graphName
```
public GSP graphName(java.lang.String graphName)
```
    Send request for a named graph (that is, ?graph=)
  - graphName
```
public GSP graphName(Node graphName)
```
    Send request for a named graph (that is, ?graph=)
  - defaultGraph
```
public GSP defaultGraph()
```
    Send request for the default graph (that is, ?default)
  - dataset
```
public GSP dataset()
```
    Send request for the dataset. This is "no GSP naming".
  - acceptHeader
```
public GSP acceptHeader(java.lang.String acceptHeader)
```
    Set the accept header on GET requests. Optional; if not set, a system default is used.
  - accept
```
public GSP accept(Lang lang)
```
    Set the accept header on GET requests. Optional; if not set, a system default is used.
  - contentTypeHeader
```
public GSP contentTypeHeader(java.lang.String contentType)
```
    Set the Content-type for a POST, PUT request of a file or serialization of a graph opf dataset is necessary. Optional; if not set, the file extension is used or the system default RDF syntax encoding.
  - contentType
```
public GSP contentType(RDFFormat rdfFormat)
```
    Set the Content-type for a POST, PUT request of a file or serialization of a graph opf dataset is necessary. Optional; if not set, the file extension is used or the system default RDF syntax encoding.
  - GET
```
public Graph GET()
```
    Get a graph
  - POST
```
public void POST(java.lang.String file)
```
    POST the contents of a file using the filename extension to determine the Content-Type to use if it is not already set.
    This operation does not parse the file.
  - POST
```
public void POST(Graph graph)
```
    POST a graph.
  - PUT
```
public void PUT(java.lang.String file)
```
    PUT the contents of a file using the filename extension to determine the Content-Type to use if it is not already set.
    This operation does not parse the file.
    If the data may have quads (named graphs), use putDataset(String).
  - PUT
```
public void PUT(Graph graph)
```
    PUT a graph.
  - DELETE
```
public void DELETE()
```
    Delete a graph.
  - getDataset
```
public DatasetGraph getDataset()
```
    GET dataset.
    If the remote end is a graph, the result is a dataset with that graph data in the default graph of the dataset.
  - postDataset
```
public void postDataset(java.lang.String file)
```
    POST the contents of a file using the filename extension to determine the Content-Type to use if not already set.
    This operation does not parse the file.
  - postDataset
```
public void postDataset(DatasetGraph dataset)
```
    POST a dataset
  - putDataset
```
public void putDataset(java.lang.String file)
```
    PUT the contents of a file using the filename extension to determine the Content-Type to use if not already set.
    This operation does not parse the file.
  - putDataset
```
public void putDataset(DatasetGraph dataset)
```
    PUT a dataset
  - clearDataset
```
public void clearDataset()
```
    Clear - delete named graphs, empty the default graph - SPARQL "CLEAR ALL"
