Interface TrajectoryFeature

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 - on i/o error
