ISO 21090 Model

The LexEVS 6.0 Analytical Grid Services use a version of the LexGRID/LexBIG model, extended to support ISO 21090 Datatypes.

...

Description:

Returns an instance of the sort extension registered with the given name.

Input:

org.LexGrid.LexBIG.iso21090.DataModel.cagrid.ExtensionIdentification

Output:

org.LexGrid.LexBIG.cagrid.LexBIGCaGridServices.Sort.stubs.types.SortReference

Exception:

RemoteException

Implementation Details:

Implementation :

  • Step 1: Create a Resource on the server and populate it with the requested org.LexGrid.LexBIG.Extensions.Query.Sort
  • Step 2: Return the Client Reference to the user. This Reference has the above org.LexGrid.LexBIG.cagrid.LexBIGCaGridServices.Sort.client.SortClient as a Resource. This client is a Service Context that allows the user to call regular org.LexGrid.LexBIG.Extensions.Query.Sort API calls through the grid service. An org.LexGrid.LexBIG.cagrid.LexBIGCaGridServices.Sort.client.SortClient object is built from the above Reference. This SortClient implements the Interface org.LexGrid.LexBIG.Extensions.Query.Sort. This makes calling Grid Service Calls through org.LexGrid.LexBIG.cagrid.LexBIGCaGridServices.Sort.client.SortClient transparent to the end user.

Sample Call

Sample Call :

  • Step 1: Connect to the LexEVS caGrid Service using the org.LexGrid.LexBIG.cagrid.adapters.LexBIGServiceAdapter or org.LexGrid.LexBIG.cagrid.adapters.LexBIGServiceGridAdapter.

    Code Block
    LexBIGServiceGrid lbs = new LexBIGServiceGridAdapter(url);

  • Step 2: Build an org.LexGrid.LexBIG.iso21090.DataModel.cagrid.ExtensionIdentificationto hold the Extension name.

    Code Block
    ExtensionIdentification extension = new ExtensionIdentification(); extension.setLexBIGExtensionName(name);

  • Step 3: Invoke the LexEVS caGrid service as follows:

    Code Block
    
Filter filter = lbs.getSortAlgorithm(extension);
