Member Function Documentation

◆ Accept()

void wsf::space::AscendingRadiusCondition::Accept ( OrbitalPropagatorConditionVisitor & aVisitor )

overridevirtual

Accept a visitor.

Implements wsf::space::OrbitalPropagatorCondition.

References wsf::space::OrbitalPropagatorConditionVisitor::Accept().

◆ Clone()

AscendingRadiusCondition * wsf::space::AscendingRadiusCondition::Clone ( ) const

inlineoverridevirtual

Return a copy of this object. Must be implemented by all derived types. If cloning is impossible, a WsfUncloneableException should be thrown.

Implements wsf::space::OrbitalPropagatorCondition.

References AscendingRadiusCondition().

◆ GetConditionString()

std::string wsf::space::AscendingRadiusCondition::GetConditionString ( ) const

inlineoverridevirtual

Return the string identifying the condition.

Implements wsf::space::OrbitalPropagatorCondition.

◆ InitialGuess()

std::pair< bool, double > wsf::space::AscendingRadiusCondition::InitialGuess ( const UtOrbitalPropagatorBase & aPropagator ) const

overridevirtual

Produce an initial guess for when the condition might obtain. The initial guess produced by this method is used to set the initial search area for the root. In some rare cases, it may be impossible to form an initial guess.

Parameters

aPropagator - The propagator for which an initial guess is to be returned.

Returns: - a pair, with a first member set to true if an initial guess was able to be computed, and a second member set to the time of the initial guess.

Implements wsf::space::OrbitalPropagatorOptimizingCondition.

References wsf::space::OrbitalPropagatorCondition::mOrbitNumber, wsf::space::RadiusCondition::mRadius, and ok.

◆ Objective()

bool wsf::space::AscendingRadiusCondition::Objective	(	UtOrbitalPropagatorBase &	aPropagator,
		const UtCalendar &	aBaseEpoch,
		double	aOffsetTime ) const

overridevirtual

This function is the objective function whose root gives the time of the condition. The provided propagator will be advanced to aOffsetTime seconds after the provided aBaseEpoch and the resulting state will be used to evaluate the condition. The condition needs to be formulated so that a boolean is returned, where the value of the boolean indicates if aOffsetTime is in a region before or after the root. The condition can return either true or false for values before the root, and the choice is up to the convenience of the implementer.

Parameters

aPropagator	- The propagator for which the objective is being examined.
aBaseEpoch	- A base epoch from which the offset will be specified.
aOffsetTime	- The offset from the base epoch at which the objective will be computed.

Returns: If the given aOffsetTime is before the root.

Implements wsf::space::OrbitalPropagatorOptimizingCondition.
