Class OrphanFrame

java.lang.Object

org.orekit.frames.OrphanFrame

All Implemented Interfaces:

Serializable

public class OrphanFrame
extends Object
implements Serializable

Prototype frame that can be built from leaf to roots and later attached to a tree.

Regular Frame instances can be built only from a parent frame, i.e. the frames tree can be built only from root to leafs. In some cases, it may desirable to build a subset tree and attach it to the main tree after build time, which means the tree is built from leafs to root. This class allows building this subtree.

During the build process, the Frame associated with each OrphanFrame is not available. It becomes available only once the OrphanFrame has been attached to the main tree, and at this time it can be used to compute transforms.

Constructor Detail

OrphanFrame

public OrphanFrame(String name)

Simple constructor.

Parameters:

name - name of the frame

Method Detail

addChild

public void addChild(OrphanFrame child,
                     Transform transform,
                     boolean isPseudoInertial)
              throws OrekitException

Add a child.

If a child is added after the instance has been attached, the child and all its tree will be attached immediately too.

Parameters:

child - child to add

transform - transform from instance to child

isPseudoInertial - true if child is considered pseudo-inertial (i.e. suitable for propagating orbit)

Throws:

OrekitException - if child frame has already been attached to either an OrphanFrame or to a Frame

addChild

public void addChild(OrphanFrame child,
                     TransformProvider transformProvider,
                     boolean isPseudoInertial)
              throws OrekitException

Add a child.

If a child is added after the instance has been attached, the child and all its tree will be attached immediately too.

Parameters:

child - child to add

transformProvider - provider for transform from instance to child

isPseudoInertial - true if child is considered pseudo-inertial (i.e. suitable for propagating orbit)

Throws:

OrekitException - if child frame has already been attached to either an OrphanFrame or to a Frame

attachTo

public void attachTo(Frame parent,
                     Transform transform,
                     boolean isPseudoInertial)
              throws OrekitException

Attach the instance (and all its children down to leafs) to the main tree.

Parameters:

parent - parent frame to attach to

transform - transform from parent frame to instance

isPseudoInertial - true if frame is considered pseudo-inertial (i.e. suitable for propagating orbit)

Throws:

OrekitException - if child frame has already been attached to either an OrphanFrame or to a Frame

attachTo

public void attachTo(Frame parent,
                     TransformProvider transformProvider,
                     boolean isPseudoInertial)
              throws OrekitException

Attach the instance (and all its children down to leafs) to the main tree.

Parameters:

parent - parent frame to attach to

transformProvider - provider for transform from parent frame to instance

isPseudoInertial - true if frame is considered pseudo-inertial (i.e. suitable for propagating orbit)

Throws:

OrekitException - if child frame has already been attached to either an OrphanFrame or to a Frame

getChildren

public List<OrphanFrame> getChildren()

Get all children of the instance.

Returns:

unmodifiable list of children

getFrame

public Frame getFrame()
               throws OrekitException

Get the associated frame.

Returns:

associated frame

Throws:

OrekitException - if instance has not been attached to the frames tree

toString

public String toString()

Overrides:

toString in class Object
