      public int getNDimensionIndex(int n)
      Utility method to retrieve the index of a specific dimension index, for constructing the range
      Parameters:
      n - the dimension to retrieve the index for (0=Z, 1=T, 2+=Additional)
      Returns:
      the index
    • getNIndex

      public int getNIndex(int n, int imageIndex)
      Utility method to retrieve the n-index of a Variable coverageDescriptor stored on NetCDFImageReader NetCDF Flat Reader HashMap indexMap.
      Parameters:
      n - int the dimension
      imageIndex - int the image index
      Returns:
      n-index int -1 if not present
    • splitIndex

      public int[] splitIndex(int imageIndex)
      Utility method to split the index of a Variable coverageDescriptor stored on NetCDFImageReader NetCDF Flat Reader HashMap indexMap into dimensions.
      Parameters:
      imageIndex - int the index
      Returns:
      splitted index
    • mapIndex

    • getFeatures

      public int getFeatures(int startIndex, int limit, ListFeatureCollection collection)
      Return features for that variable adapter, starting from slices with index = "startIndex", and up to "limit" elements. This allows for paging. Put the created features inside the provided collection
      Parameters:
      startIndex - the first slice to be returned
      limit - the max number of features to be created
      collection - the feature collection where features need to be stored
