Detailed Description

Current state of a geodesic integration.

Member Typedef Documentation

typedef Gyoto::SmartPointer<Gyoto::SmartPointee> Gyoto::SmartPointee::Subcontractor_t(Gyoto::FactoryMessenger *)

inherited

A subcontractor builds an object upon order from the Factory.

Various classes need to provide a subcontractor to be able to instanciate themselves upon order from the Factory. A subcontractor is a function (often a static member function) which accepts a pointer to a FactoryMessenger as unique parameter, communicates with the Factory using this messenger to read an XML description of the object to build, and returns this objet. SmartPointee::Subcontractor_t* is just generic enough a typedef to cast to and from other subcontractor types: Astrobj::Subcontractor_t, Metric::Subcontractor_t, Spectrum::Subcontractor_t. A subcontractor needs to be registered using the relevant Register() function: Astrobj::Register(), Metric::Register(), Spectrum::Register().

Constructor & Destructor Documentation

Gyoto::Worldline::IntegState::IntegState	(	Worldline *	line,
		const double *	coord,
		const double	delta
	)

Constructor.

Parameters

line	The Worldline that we are integrating. Sets: Worldline::line_, Worldline::gg_, Worldline::adaptive_.
coord	Initial coordinate.
delta	Integration step. Sign determines direction.

Member Function Documentation

virtual int Gyoto::Worldline::IntegState::nextStep ( double *  coord )

virtual

Make one step.

Parameters

[out]

coord

Next position-velocity;

Member Data Documentation

bool Gyoto::Worldline::IntegState::adaptive_

private

Whether Worldline::delta_ is adaptive.

Taken from Worldline::line_, never updated.

Gyoto::SmartPointer<Gyoto::Metric::Generic> Gyoto::Worldline::IntegState::gg_

private

The Metric in this end of the Universe.

Taken from Worldline::line_, never updated.

Worldline* Gyoto::Worldline::IntegState::line_

private

Worldline that we are integrating.

Beware this is not a SmartPointer. Make sure line_ still exists when calling nestStep().
