Package Array.streamerOrigin

Class GPSOriginIterator

java.lang.Object

Array.streamerOrigin.OriginIterator

Array.streamerOrigin.GPSOriginIterator

All Implemented Interfaces:

Iterator<GpsData>, ListIterator<GpsData>

public class GPSOriginIterator
extends OriginIterator

This is more complicated than the stramerDataIterator since it needs to combine data from two sources. First it needs to find the most appropriate streamer data for the given time, then it needs to find the closest GPS data to that time, then it needs to combine the two. The main iteration will actually be over GPS data, then for each GPS position find the closest (or interpolate) streamer data, then make a new streamer data unit that contains the gps data to return to the loacliser.
