origin - the new origin.

frame - the existing frame that specifies the orientation.

Method Details

getTransform

public Transform getTransform(AbsoluteDate date)

Description copied from interface: TransformProvider

Get the Transform corresponding to specified date.

Specified by:

getTransform in interface TransformProvider

Parameters:

date - current date

Returns:

transform at specified date

getTransform

public <T extends CalculusFieldElement<T>>
FieldTransform<T> getTransform(FieldAbsoluteDate<T> date)

Description copied from interface: TransformProvider

Get the FieldTransform corresponding to specified date.

Specified by:

getTransform in interface TransformProvider

Type Parameters:

T - type of the field elements

Parameters:

date - current date

Returns:

transform at specified date

getKinematicTransform

public KinematicTransform getKinematicTransform(AbsoluteDate date)

Description copied from interface: TransformProvider

Get a transform for position and velocity, not acceleration.

The default implementation returns TransformProvider.getTransform(AbsoluteDate) but implementations may override it for better performance.

Specified by:

getKinematicTransform in interface TransformProvider

Parameters:

date - current date.

Returns:

the kinematic transform.

getKinematicTransform

public <T extends CalculusFieldElement<T>>
FieldKinematicTransform<T> getKinematicTransform(FieldAbsoluteDate<T> date)

Description copied from interface: TransformProvider

Get a transform for position and velocity, not acceleration.

The default implementation returns TransformProvider.getTransform(AbsoluteDate) but implementations may override it for better performance.

Specified by:

getKinematicTransform in interface TransformProvider

Type Parameters:

T - type of the elements

Parameters:

date - current date.

Returns:

the kinematic transform.

getStaticTransform

public StaticTransform getStaticTransform(AbsoluteDate date)

Description copied from interface: TransformProvider

Get a transform for only rotations and translations on the specified date.

The default implementation calls TransformProvider.getTransform(AbsoluteDate) but implementations may override it for better performance.

Specified by:

getStaticTransform in interface TransformProvider

Parameters:

date - current date.

Returns:

the static transform.

getStaticTransform

public <T extends CalculusFieldElement<T>>
FieldStaticTransform<T> getStaticTransform(FieldAbsoluteDate<T> date)

Description copied from interface: TransformProvider

Get a transform for only rotations and translations on the specified date.

The default implementation returns TransformProvider.getTransform(AbsoluteDate) but implementations may override it for better performance.

Specified by:

getStaticTransform in interface TransformProvider

Type Parameters:

T - type of the elements

Parameters:

date - current date.

Returns:

the static transform.
