  • Method Details

    • listParameterHistory

      public abstract void listParameterHistory(T ctx, ListParameterHistoryRequest request, Observer<ListParameterHistoryResponse> observer)
        List parameter history

    • exportParameterValues

      public abstract void exportParameterValues(T ctx, ExportParameterValuesRequest request, Observer<HttpBody> observer)
        Export parameter values in CSV format

    • streamParameterValues

      public abstract void streamParameterValues(T ctx, StreamParameterValuesRequest request, Observer<Pvalue.ParameterData> observer)
        Streams back parameter values

    • loadParameterValues

      public abstract Observer<LoadParameterValuesRequest> loadParameterValues(T ctx, Observer<LoadParameterValuesResponse> observer)
        Load (inject) a stream of parameter values

    • getParameterSamples

      public abstract void getParameterSamples(T ctx, GetParameterSamplesRequest request, Observer<Pvalue.TimeSeries> observer)
        Get parameter samples
 
  This divides the query interval in a number of intervals and returns aggregated
  statistics (max, min, avg) about each interval.
 
  This operation is useful when making high-level overviews (such as plots) of a
  parameter's value over large time intervals without having to retrieve each
  and every individual parameter value.
 
  By default this operation fetches data from the parameter archive and/or
  parameter cache. If these services are not configured, you can still get
  correct results by specifying the option `source=replay` as detailed below.

    • getParameterRanges

      public abstract void getParameterRanges(T ctx, GetParameterRangesRequest request, Observer<Pvalue.Ranges> observer)
        Get parameter ranges
 
  A range is a tuple `(start, stop, value, count)` that represents the time
  interval for which the parameter has been steadily coming in with the same
  value. This request is useful for retrieving an overview for parameters that
  change unfrequently in a large time interval. For example an on/off status
  of a device, or some operational status. Two consecutive ranges containing
  the same value will be returned if there was a gap in the data. The gap is
  determined according to the parameter expiration time configured in the
  Mission Database.

    • listParameterGroups

      public abstract void listParameterGroups(T ctx, ListParameterGroupsRequest request, Observer<ListParameterGroupsResponse> observer)
        List parameter groups
