Member Typedef Documentation

◆ Self

typedef BodyKinematics OpenSim::BodyKinematics::Self

This typedef might be useful within the member functions of this class.

This is generated by the OpenSim_DECLARE_*_OBJECT macros.

◆ Super

typedef Analysis OpenSim::BodyKinematics::Super

Use this typedef to refer to the superclass of this class.

Avoid using the explicit type name of the superclass; this would introduce bugs if the superclass is changed.

This is generated by the OpenSim_DECLARE_*_OBJECT macros.

Member Function Documentation

◆ assign()

void OpenSim::BodyKinematics::assign ( Object & aObject )

inlineoverride

This allows copy assignment in the Java GUI.

Exceptions

Exception if the argument is not of type BodyKinematics.

◆ begin()

int OpenSim::BodyKinematics::begin ( const SimTK::State & s )

overridevirtual

Reimplemented from OpenSim::Analysis.

◆ clone()

BodyKinematics* OpenSim::BodyKinematics::clone ( ) const

inlineoverridevirtual

Create a new heap-allocated copy of the concrete object to which this Object refers.

It is up to the caller to delete the returned object when no longer needed. Every concrete object deriving from Object implements this pure virtual method automatically, via the declaration macro it invokes (e.g., OpenSim_DECLARE_CONCRETE_OBJECT()). Note that the concrete class overrides modify the return type to be a pointer to the concrete object; that still overrides the base class method because the return type is covariant with (that is, derives from) Object.

Implements OpenSim::Analysis.

◆ end()

int OpenSim::BodyKinematics::end ( const SimTK::State & s )

overridevirtual

Reimplemented from OpenSim::Analysis.

◆ getAccelerationStorage()

Storage* OpenSim::BodyKinematics::getAccelerationStorage ( )

◆ getClassName()

static const std::string& OpenSim::BodyKinematics::getClassName ( )

inlinestatic

This returns "BodyKinematics".

See getConcreteClassName() if you want the class name of the underlying concrete object instead.

This is generated by the OpenSim_DECLARE_*_OBJECT macros.

◆ getConcreteClassName()

const std::string& OpenSim::BodyKinematics::getConcreteClassName ( ) const

inlineoverridevirtual

Returns the class name of the concrete Object-derived class of the actual object referenced by this Object, as a string.

This is the string that is used as the tag for this concrete object in an XML file. Every concrete class derived from Object automatically overrides this method via the declaration macro it uses. See getClassName() to get the class name of the referencing (possibly abstract) class rather than the concrete object.

See also: getClassName()

Implements OpenSim::Analysis.

◆ getExpressResultsInLocalFrame()

bool OpenSim::BodyKinematics::getExpressResultsInLocalFrame ( )

◆ getPositionStorage()

Storage* OpenSim::BodyKinematics::getPositionStorage ( )

◆ getVelocityStorage()

Storage* OpenSim::BodyKinematics::getVelocityStorage ( )

◆ operator=()

BodyKinematics& OpenSim::BodyKinematics::operator= ( const BodyKinematics & aBodyKinematics )

◆ printResults()

int OpenSim::BodyKinematics::printResults	(	const std::string &	aBaseName,
		const std::string &	aDir = `""`,
		double	aDT = `-1.0`,
		const std::string &	aExtension = `".sto"`
	)

overridevirtual

Print the results of the analysis.

Parameters

aBaseName	Base name of file to which to print the data.
aDir	Directory name.
aDT	Time interval between results (linear interpolation is used). If not supplied as an argument or negative, all time steps are printed without interpolation.
aExtension	File extension if not the default ".sto".

Returns: -1 on error, 0 otherwise.

Reimplemented from OpenSim::Analysis.

◆ record()

virtual int OpenSim::BodyKinematics::record ( const SimTK::State & s )

protectedvirtual

◆ safeDownCast()

static BodyKinematics* OpenSim::BodyKinematics::safeDownCast ( OpenSim::Object * obj )

inlinestatic

For use in MATLAB and Python to access the concrete class.

Example: cObj = BodyKinematics.safeDownCast(obj). This is equivalent to dynamic_cast<BodyKinematics*>(obj) in C++.

◆ setBodiesToRecord()

void OpenSim::BodyKinematics::setBodiesToRecord ( Array< std::string > & listOfBodies )

inline

◆ setExpressResultsInLocalFrame()

void OpenSim::BodyKinematics::setExpressResultsInLocalFrame ( bool aTrueFalse )

◆ setModel()

void OpenSim::BodyKinematics::setModel ( Model & aModel )

overridevirtual

set pointer to model to be analyzed.

Parameters

aModel

Reimplemented from OpenSim::Analysis.

◆ setRecordCenterOfMass()

void OpenSim::BodyKinematics::setRecordCenterOfMass ( bool aTrueFalse )

inline

◆ setStorageCapacityIncrements()

void OpenSim::BodyKinematics::setStorageCapacityIncrements ( int )
