Class DateMotionCollection1<T>

java.lang.Object

agi.foundation.DateMotionCollection1<T>

Type Parameters:

T - The type of Motion1 that this collection contains. For example, if T is Cartesian, then this collection holds Motion<Cartesian>.

All Implemented Interfaces:

IDateMotionCollection1<T>

public class DateMotionCollection1<T>
extends Object
implements IDateMotionCollection1<T>

A collection of Motion1, each of which is associated with a particular JulianDate. This is a convenient and efficient way to store time-varying position and velocity, etc. Each Motion1 instance is required to have the same Order (get).

Constructor Detail

DateMotionCollection1

public DateMotionCollection1()

Initializes a new instance. The order of the collection will be determined by the first item added to it.

DateMotionCollection1

public DateMotionCollection1(int size,
                             int order)

Initializes a new instance with a particular size and order.

After constructing a new instance with this constructor, the Count (get) property will return size and DateMotionCollection1.setItem(int,JulianDate,Object) can be used to set the value at a particular index. Also, the Order (get) property will return order.

Parameters:

size - The number of items in the collection.

order - The number of derivatives that the collection should store.

Method Detail

getCount

public final int getCount()

Gets the number of items in this collection.

Specified by:

getCount in interface IDateMotionCollection1<T>

getOrder

public final int getOrder()

Gets the number of derivatives in this collection.

Specified by:

getOrder in interface IDateMotionCollection1<T>

getDates

public final List<JulianDate> getDates()

Gets the list of dates in this collection.

Specified by:

getDates in interface IDateMotionCollection1<T>

getMotions

public final List<Motion1<T>> getMotions()

Gets the list of motion instances in this collection. Consider using Values (get), FirstDerivatives (get), SecondDerivatives (get), etc. to get all of the corresponding data as a single list. This is more efficient than requesting a list of motion instances.

Specified by:

getMotions in interface IDateMotionCollection1<T>

get

public final List<T> get(int index)

Gets the list of the specified derivative.

Specifying an index of 0 retrieves a list of all values in the collection. Specifying 1 retrieves a list of all first derivatives. Specifying 2 retrieves a list of all second derivatives. And so on.

Specified by:

get in interface IDateMotionCollection1<T>

Parameters:

index - The derivative list to retrieve.

Returns:

The requested list.

getValues

public final List<T> getValues()

Gets the list of values in the collection.

Specified by:

getValues in interface IDateMotionCollection1<T>

Specified by:

getFirstDerivatives in interface IDateMotionCollection1<T>

getSecondDerivatives

public final List<T> getSecondDerivatives()

Gets the list of second derivatives in the collection.

Specified by:
