TrajectoryFeature (cdm-core 5.6.0 API)

All Superinterfaces:

DsgFeatureCollection, Iterable<PointFeature>, PointFeatureCollection

All Known Implementing Classes:

TrajectoryFeatureImpl
```
public interface TrajectoryFeature
extends PointFeatureCollection
```
A set of observations along a 1 dimensional path, connected in space and time. The observations are ordered in time (in other words, the time dimension must increase monotonically along the trajectory).

- Method Detail
  - size
```
int size()
```
    The number of points along the trajectory. May not be known until after iterating through the collection.
    
    Specified by:
    
    size in interface DsgFeatureCollection
    
    Returns:
    
    number of points along the trajectory, or -1 if not known.
  - getCalendarDateRange
```
CalendarDateRange getCalendarDateRange()
```
    DateRange for the points along the trajectory. May not be known until after iterating through the collection.
    
    Specified by:
    
    getCalendarDateRange in interface DsgFeatureCollection
    
    Returns:
    
    stating date for the trajectory, or null if not known
  - getBoundingBox
```
LatLonRect getBoundingBox()
```
    BoundingBox for the trajectory. May not be known until after iterating through the collection.
    
    Specified by:
    
    getBoundingBox in interface DsgFeatureCollection
    
    Returns:
    
    BoundingBox for the trajectory, or null if not known.
  - getFeatureData
```
@Nonnull
StructureData getFeatureData()
                      throws IOException
```
    The actual data of just this Trajectory feature.
    
    Returns:
    
    the actual data of this Trajectory, may not be null but may be empty.
    
    Throws:
    
    IOException
