    • getSpec

      public Spec getSpec()
      Description copied from interface: YamcsService
      Returns the valid configuration options for this service.
      Returns:
      the argument specification, or null if the args should not be validated.

    • init

      public void init(String yamcsInstance, String serviceName, YConfiguration config) throws InitException
      Description copied from interface: YamcsService
      Initialize this service. This is called before the service is started. All operations should finish fast.
      Specified by:
      init in interface YamcsService
      Overrides:
      init in class AbstractYamcsService
      Parameters:
      yamcsInstance - The yamcs instance, or null if this is a global service.
      serviceName - The service name.
      config - The configured arguments for this service. If YamcsService.getSpec() is implemented then this contains the arguments after being validated (including any defaults).
      Throws:
      InitException - When something goes wrong during the execution of this method.
