      Cumulative counter of transactions

  • Method Details

    • newBuilder

      public static DataService.Builder newBuilder()
      Builder for a new DataService.

    • newBuilder

      public static DataService.Builder newBuilder(org.apache.jena.sparql.core.DatasetGraph dsg)
      Builder for a new DataService, with a dataset.

    • newBuilder

      public static DataService.Builder newBuilder(DataService dSrv)
      Return a new builder, populated by an existing DatasetService

    • getDataset

      public org.apache.jena.sparql.core.DatasetGraph getDataset()

    • getEndpointSet

      public EndpointSet getEndpointSet(String endpointName)
      Return the EndpointSet for the operations for named use.

    • getEndpointSet

      public EndpointSet getEndpointSet()
      Return the EndpointSet for the operations for unnamed use.

    • getEndpoints

      public Collection<Endpoint> getEndpoints()
      Return a collection of all endpoints for this DataService.

    • forEachEndpoint

      public void forEachEndpoint(Consumer<Endpoint> action)
      Execute an action for each Endpoint.

    • getEndpoints

      public List<Endpoint> getEndpoints(Operation operation)

    • getOperations

      public Collection<Operation> getOperations()
      Return the operations available here.
      See Also:

    • hasOperation

      public boolean hasOperation(Operation operation)
      Return the operations available here.

    • setEndpointProcessors

      public void setEndpointProcessors(OperationRegistry operationRegistry)
      Set any ActionService processors that are currently unset.

    • getDefaultOperationChooser

      public DispatchFunction getDefaultOperationChooser()
      Decision function for this DataService.

      This is the handler for the case of "no query string, no registered content-type" that occurs when a name has multiple choices in the dispatcher so the operation can not be distinguished.

      If null, the system default (in Dispatcher.selectPlainOperation) is a quads performed on the dataset - Operation.GSP_R or Operation.GSP_RW.
