TrajectoryObsDatatype (NetCDF-Java Library 4.3.16 API)

```
public interface TrajectoryObsDatatype
```
A sequence (one-dimensional, variable-length list) of PointObsDatatype, connected in space and time. The observations are ordered in time (in other words, the time dimension must increase monotonically along the trajectory).

    Returns:

```
DataIterator getDataIterator(int bufferSize)
                             throws IOException
```
    Get an efficient iterator over all the data in the Trajectory in time order. This is an optional method; it will return null if no iterator is available. This is the efficient way to get all the data, it can be 100 times faster than getData(). This will return an iterator over type getDataClass(), and the actual data has already been read into memory, that is, dataType.getData() will not incur any I/O.
    This is accomplished by buffering bufferSize amount of data at once. You must fully process the data, or copy it out of the StructureData, as you iterate over it, in order for the garbage collector to work.
    We dont need a cancelTask, just stop the iteration if the user want to cancel.
    
    Parameters:
    bufferSize - if > 0, the internal buffer size, else use the default. Typically 100k - 1M for best results.
    
    Returns:
    Iterator over type PointObsDatatype, time order; or null if not available.
    
    Throws:
    
    IOException
  - getFullRange

```
    Get a range for a single point in the trajectory.
    
    Throws:
    
    InvalidRangeException
  - getRange
```

             int end,
