Method Detail

buildPropagator

public Propagator buildPropagator(AbsoluteDate date,
                         double[] parameters)
                           throws OrekitException

Build a propagator.

Parameters:

date - date associated to the parameters to configure the initial state

parameters - set of position/velocity(/free) parameters to configure the propagator

Returns:

an initialized propagator

Throws:

OrekitException - if propagator cannot be build

getParameter

public double getParameter(String name)
                    throws OrekitIllegalArgumentException

Get parameter value from its name.

The abstract base class only supports NewtonianAttraction.CENTRAL_ATTRACTION_COEFFICIENT, specialized propagator builders may support more parameters.

Specified by:

getParameter in interface PropagatorBuilder

Overrides:

getParameter in class AbstractPropagatorBuilder

Parameters:

name - parameter name

Returns:

parameter value

Throws:

OrekitIllegalArgumentException - if parameter is not supported

setParameter

public void setParameter(String name,
                double value)
                  throws OrekitIllegalArgumentException

Set parameter value from its name.

The abstract base class only supports NewtonianAttraction.CENTRAL_ATTRACTION_COEFFICIENT, specialized propagator builders may support more parameters.

Specified by:

setParameter in interface PropagatorBuilder

Overrides:

setParameter in class AbstractPropagatorBuilder

Parameters:

name - parameter name

value - parameter value

Throws:

OrekitIllegalArgumentException - if parameter is not supported
