org.apache.jena.sparql.exec.http.DSP

public class DSP extends StoreProtocol<DSP>

Client for dataset operations over HTTP.

for graph operations, see GSP which is the client-side of SPARQL 1.1 Graph Store Protocol.

This class provided GET, POST, PUT and clear() on datasets. DELETE is not supported. HTTP DELETE means "remove resource", not "clear resource".

Examples:

   // Get the dataset.
   DatasetGraph graph = DSP.service("http://example/dataset").GET();

   // POST (add) to a dataset
   DatasetGraph myData = ...;
   GSP.service("http://example/dataset").POST(myData);

Method Details
- service
  
  public static DSP service(String service)
  
  Create a request to the remote service.
- request
  
  public static DSP request()
  
  Create a request to the remote service (without GSP naming). Call StoreProtocol.endpoint(java.lang.String) to set the target.
- GET
  
  public DatasetGraph GET()
  
  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.
- POST
  
  public void POST(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.
- POST
  
  public void POST(DatasetGraph dataset)
  
  POST a dataset
- PUT
  
  public void PUT(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.
- PUT
  
  public void PUT(DatasetGraph dataset)
  
  PUT a dataset
- clear
  
  public void clear()
  
  Clear - delete named graphs, empty the default graph - similar to SPARQL "CLEAR ALL"
