IDateMotionCollection2<T,TDerivative>

public class DateMotionCollection2<T,TDerivative>
extends Object

Constructor Detail

DateMotionCollection2

public DateMotionCollection2()

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

DateMotionCollection2

public DateMotionCollection2(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 DateMotionCollection2.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 IDateMotionCollection2<T,TDerivative>

getOrder

public final int getOrder()

Gets the number of derivatives in this collection.

Specified by:

getOrder in interface IDateMotionCollection2<T,TDerivative>

getDates

public final List<JulianDate> getDates()

Gets the list of dates in this collection.

Specified by:

getDates in interface IDateMotionCollection2<T,TDerivative>

getMotions

public final List<Motion2<T,TDerivative>> 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 IDateMotionCollection2<T,TDerivative>

get

public final List<TDerivative> 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 IDateMotionCollection2<T,TDerivative>

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:
