virtual void	propagate (const base::State state, const Control control, double duration, base::State *result) const =0
	Propagate from a state, given a control, for some specified amount of time (the amount of time can also be negative, if canPropagateBackward() returns true) More...

virtual bool	canPropagateBackward () const
	Some systems can only propagate forward in time (i.e., the duration argument for the propagate() function is always positive). If this is the case, this function should return false. Planners that need backward propagation (negative durations) will call this function to check. If backward propagation is possible, this function should return true (this is the default).

virtual bool	steer (const base::State , const base::State , Control *, double &) const
	Compute the control that can take the system from state from to state to. Store that control in result; the duration for which the control should be applied is stored in duration; return true if the computation was successful; return false otherwise;. More...

virtual bool	canSteer () const
	Return true if the steer() function has been implemented.

◆ propagate()

virtual void ompl::control::StatePropagator::propagate	(	const base::State *	state,
		const Control *	control,
		double	duration,
		base::State *	result
	)		const

pure virtual

Propagate from a state, given a control, for some specified amount of time (the amount of time can also be negative, if canPropagateBackward() returns true)

Parameters

state	the state to start propagating from
control	the control to apply
duration	the duration for which the control is applied
result	the state the system is brought to

Note: This function is not used for integration internally. If integrating a system of differential equations is needed, this should be implemented inside the propagate() function.; The pointer to the starting state and the result state may be the same.

Implemented in KoulesStatePropagator, ompl::control::OpenDEStatePropagator, and ompl::control::MorseStatePropagator.

◆ steer()

virtual bool ompl::control::StatePropagator::steer	(	const base::State *	,
		const base::State *	,
		Control *	,
		double &
	)		const

inlinevirtual

Compute the control that can take the system from state from to state to. Store that control in result; the duration for which the control should be applied is stored in duration; return true if the computation was successful; return false otherwise;.

Note: If false is returned, the content of result and duration may have been changed, but it does not represent a solution;
