Getting WITSML data from the server

All data is retrieved through a WitsmlServer instance which represents the WITSML server in the client program.

There are three different ways to get data:

1. Get multiple children of a given type from a specific parent

     
     // Get all wellbores from a given well instance
     List<WitsmlWellbore> wellbores = witsmlServer.get(WitsmlWellbore.class,
                                                       new WitsmlQuery(),
                                                       well);

     
     // Get all rigs from a given wellbore instance
     List<WitsmlRig> rigs = witsmlServer.get(WitsmlRig.class,
                                             new WitsmlQuery(),
                                             wellbore);

     
     // ... or through the wellbore ID
     List<WitsmlRig> rigs = witsmlServer.get(WitsmlRig.class,
                                             new WitsmlQuery(),
                                             "ID-wellbore");

     
     // Both parent and grandparent may be specified
     List<WitsmlMudLog> mudLogs = witsmlServer.get(WitsmlMudLog.class,
                                                   new WitsmlQuery(),
                                                   "ID-wellbore",
                                                   "ID-well");

     
     // Wells doesn't have parents so we can skip the parent argument
     List<WitsmlWell> wells = witsmlServer.get(WitsmlWell.class,
                                               new WitsmlQuery());

     
     // Attempt to get all rigs! Some servers will accept this approach
     // while others will require a valid wellbore parent.
     // The WITSML standard is unclear on this issue.
     List<WitsmlRig> rigs = witsmlServer.get(WitsmlRig.class,
                                             new WitsmlQuery());
