OpenSim::ControlConstant::ControlConstant	(	double	aX = `0.0`,
		const char *	aName = `"UNKOWN"`

Parameters

aX	Constant value of the control.
aName	Name of the control.

OpenSim::ControlConstant::ControlConstant ( const ControlConstant & aControl )

virtual OpenSim::ControlConstant::~ControlConstant ( )

virtual

Member Function Documentation

virtual double OpenSim::ControlConstant::getControlValue ( double aT )

virtual

Parameters

aT	Not used since the control value is constant in time.

Implements OpenSim::Control.

virtual double OpenSim::ControlConstant::getControlValueMax ( double aT = 0.0 )

virtual

Gets the maximum allowed value of this control at time aT.

Parameters

aT	Time at which to get the control.

Returns: Maximum allowed control value. If the value of the curve is not defined, _defaultMax is returned. If the control is set to extrapolate, getExtraplate, and the time is before the first node or after the last node, then an extrapolation is performed to determin the value of the control curve. Otherwise, the value of either the first control node or last control node is returned.

Implements OpenSim::Control.

virtual double OpenSim::ControlConstant::getControlValueMin ( double aT = 0.0 )

virtual

Gets the minimum allowed value of this control at time aT.

Parameters

aT	Time at which to get the control.

Returns: Minimum allowed control value. If the value of the curve is not defined, _defaultMin is returned. If the control is set to extrapolate, (see getExtraplate()), and the time is before the first node or after the last node, then an extrapolation is performed to determin the value of the control curve. Otherwise, the value of either the first control node or last control node is returned.

Implements OpenSim::Control.

virtual int OpenSim::ControlConstant::getNumParameters ( ) const

virtual

Returns the number of parameters that are used to specify the control curve.

Implements OpenSim::Control.

virtual int OpenSim::ControlConstant::getParameterList	(	double	aT,
		Array< int > &	rList
	)

virtual

Parameters

aT	time
rList	Parameter at index 0 (i.e., the value of the constant) is the only parameter on the list.

Implements OpenSim::Control.

virtual int OpenSim::ControlConstant::getParameterList	(	double	aTLower,
		double	aTUpper,
		Array< int > &	rList
	)

virtual

Gets the list of parameters that affect the control curve between two specified times and that do NOT affect the control curve below the lower of these two times.

This method is useful when solving for a set of controls for a dynamic simulation. When solving for a set of controls, one always wants to go forward in time. Therefore, one does not want to change control parameters that affect the control curve at past times.

A control parameter is included in the list only if it affects the control curve in the specified time interval AND does NOT affect the control curve below the lower bound of the specified time interval. So, it is possible that some of the parameters on the returned list could affect the control curve at times greater than the upper bound of the specified time interval.

Parameters

aTLower	Lower time bound.
aTUpper	Upper time bound.
rList	List of indices of the control parameters that affect the curve between aTLower and aTUpper but not before aTLower.

Returns: Length of rList.

Implements OpenSim::Control.
