public class GeneralSTTrackingTrajectory
extends BaseTemporalObject
implements ISTTrackingTrajectory

Is an trajectory object used to represent track of a solar event taken from HEK. It is composed of a number of individual reports linked together to represent the trajectory. This object contains the logic needed for tracking. Mainly the ability to traverse a doubly linked list of event detections to update the list of detections that are in the trajectory.

Constructor Detail

GeneralSTTrackingTrajectory

public GeneralSTTrackingTrajectory(ISTTrackingEvent headEvent,
                                   ISTTrackingEvent tailEvent)

Constructor that uses a head and tail event to point to the head of the doubly linked list of detections and the tail of the linked list of detections. This is to save having to traverse the list

Parameters:

headEvent - The head of the linked list of event detections.

tailEvent - The tail of the linked list of event detections.

GeneralSTTrackingTrajectory

public GeneralSTTrackingTrajectory(ISTTrackingEvent event)

Constructor that assumes that the head and tail event of the linked list of detections is the same object.

Parameters:

event - The event detection to be set as both the head and tail of the linked list of event detections that represent this trajectory.

Method Detail

getSTObjects

public SortedSet<ISTTrackingEvent> getSTObjects()

Description copied from interface: ISpatialTemporalTrajectory

Produces a sorted set of all the spatiotemporal objects contained in this trajectory. The objects are ordered by their start time.

Specified by:

getSTObjects in interface ISpatialTemporalTrajectory<ISTTrackingEvent>

Returns:

A sorted set of all the spatiotemporal objects in this trajectory.

getMBR

public org.locationtech.jts.geom.Envelope getMBR()

Specified by:

getMBR in interface ISpatialTemporalTrajectory<ISTTrackingEvent>

Returns:

size

public int size()

Description copied from interface: ISpatialTemporalTrajectory

Gets the number of spatiotemporal objects contained in this trajectory.

Specified by:

size in interface ISpatialTemporalTrajectory<ISTTrackingEvent>

Returns:

The number of spatiotemporal objects in this trajectory.

getVolume

public double getVolume()

Description copied from interface: ISpatialTemporalTrajectory

Computes the volume of this trajectory by using the volume of each of the spatiotemporal objects it contains.

Specified by:

getVolume in interface ISpatialTemporalTrajectory<ISTTrackingEvent>

Returns:

The volume of the trajectory.

getTimePeriod

public org.joda.time.Interval getTimePeriod()

Description copied from interface: IBaseTemporalObject

Returns the time period that the object is valid for

Specified by:

getTimePeriod in interface IBaseTemporalObject

Overrides:

getTimePeriod in class BaseTemporalObject

Returns:

The interval over which the data type is valid.

getFirst

public ISTTrackingEvent getFirst()

Description copied from interface: ISTTrackingTrajectory

Returns the first event in the track

Specified by:

getFirst in interface ISTTrackingTrajectory

Returns:

the first event in the track

getLast

public ISTTrackingEvent getLast()

Description copied from interface: ISTTrackingTrajectory

Returns the last event in the track

Specified by:

getLast in interface ISTTrackingTrajectory

Returns:

the last event in the track

getType

public EventType getType()

Description copied from interface: ISTTrackingTrajectory

Returns the event type of the track

Specified by:

getType in interface ISTTrackingTrajectory

Returns:

the event type of the track

compareTime

public int compareTime(IBaseTemporalObject baseDataType)

Description copied from interface: IBaseTemporalObject

Compares the valid time of another IBaseDataType to this object's valid time.

Specified by:

compareTime in interface IBaseTemporalObject

Overrides:

compareTime in class BaseTemporalObject

Parameters:

baseDataType - The object to compare against this object.

Returns:

a negative integer, zero, or a positive integer as the passed in object is less than, equal to, or greater than this object.
