Member Typedef Documentation

◆ Self

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

This is generated by the OpenSim_DECLARE_*_OBJECT macros.

◆ 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.

Constructor & Destructor Documentation

◆ MocoOutputConstraint()

OpenSim::MocoOutputConstraint::MocoOutputConstraint ( )
inline

Member Function Documentation

◆ assign()

void OpenSim::MocoOutputConstraint::assign ( Object aObject)
inlineoverride

This allows copy assignment in the Java GUI.

Exceptions
Exceptionif the argument is not of type MocoOutputConstraint.

◆ calcOutputValue()

double OpenSim::MocoOutputConstraint::calcOutputValue ( const SimTK::State &  ) const
protected

Calculate the Output value for the provided SimTK::State.

If using a vector Output, either the vector norm or vector element will be returned, depending on whether an index was provided via 'setOutputIndex()'. Do not call this function until 'initializeOnModelBase()' has been called.

◆ calcPathConstraintErrorsImpl()

void OpenSim::MocoOutputConstraint::calcPathConstraintErrorsImpl ( const SimTK::State &  state,
SimTK::Vector &  errors 
) const
overrideprotectedvirtual
Precondition(s):^^ The state is realized to SimTK::Stage::Position.
If you need access to the controls, you must realize to Velocity:

Implements OpenSim::MocoPathConstraint.

◆ clone()

MocoOutputConstraint* OpenSim::MocoOutputConstraint::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::MocoPathConstraint.

◆ getClassName()

static const std::string& OpenSim::MocoOutputConstraint::getClassName ( )
inlinestatic

This returns "MocoOutputConstraint".

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::MocoOutputConstraint::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::MocoPathConstraint.

◆ getDependsOnStage()

const SimTK::Stage& OpenSim::MocoOutputConstraint::getDependsOnStage ( ) const
inlineprotected

Get the "depends-on stage", or the SimTK::Stage we need to realize the system to in order to calculate the Output value.

◆ getExponent()

int OpenSim::MocoOutputConstraint::getExponent ( ) const
inline

◆ getOutputIndex()

int OpenSim::MocoOutputConstraint::getOutputIndex ( ) const
inline

◆ getOutputPath()

const std::string& OpenSim::MocoOutputConstraint::getOutputPath ( ) const
inline

◆ initializeOnModelImpl()

void OpenSim::MocoOutputConstraint::initializeOnModelImpl ( const Model ,
const MocoProblemInfo  
) const
overrideprotectedvirtual

Perform any caching.

The number of scalar constraint equations this MocoPathConstraint implements must be defined here (see setNumEquations() below).

Precondition(s):^^ The model is initialized (initSystem()) and getModel()
is available. The passed-in model is equivalent to getModel(). Use this opportunity to check for errors in user input, in addition to the checks provided in initialize().

Implements OpenSim::MocoPathConstraint.

◆ printDescriptionImpl()

void OpenSim::MocoOutputConstraint::printDescriptionImpl ( ) const
overrideprotectedvirtual

Print a more detailed description unique to each path constraint.

Reimplemented from OpenSim::MocoPathConstraint.

◆ safeDownCast()

static MocoOutputConstraint* OpenSim::MocoOutputConstraint::safeDownCast ( OpenSim::Object obj)
inlinestatic

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

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

◆ setExponent()

void OpenSim::MocoOutputConstraint::setExponent ( int  exponent)
inline

Set the exponent applied to the output value in the constraint.

This exponent is applied when minimizing the norm of a vector type output.

◆ setOutputIndex()

void OpenSim::MocoOutputConstraint::setOutputIndex ( int  index)
inline

Set the index to the value to be constrained when a vector type Output is specified.

For SpatialVec Outputs, indices 0, 1, and 2 refer to the rotational components and indices 3, 4, and 5 refer to the translational components. A value of -1 indicates to constrain the vector norm (which is the default setting). If an index for a type double Output is provided, an exception is thrown.

◆ setOutputPath()

void OpenSim::MocoOutputConstraint::setOutputPath ( std::string  path)
inline

Set the absolute path to the output in the model to be used in this path constraint.

The format is "/path/to/component|output_name".

◆ setValueToExponent()

double OpenSim::MocoOutputConstraint::setValueToExponent ( double  value) const
inlineprotected

Raise a value to the exponent set via 'setExponent()'.

Do not call this function until 'initializeOnModelBase()' has been called.
