Detailed Description

This class describes a workflow for processing a table using TableOperators.

The user must provide a source table either as a filepath to a table or an in-memory TimeSeriesTable. In C++, one can easily chain together the operators in a processor using the C++ pipe operator:

TableProcessor proc = TableProcessor("file.sto") | TabOpLowPassFilter(6);
Examples:
example2DWalking.cpp, example2DWalkingMetabolics.cpp, exampleMocoInverse.cpp, and exampleMocoTrack.cpp.

Constructor & Destructor Documentation

◆ TableProcessor() [1/3]

OpenSim::TableProcessor::TableProcessor ( )
inline

This constructor is only for use when reading (deserializing) from an XML file.

◆ TableProcessor() [2/3]

OpenSim::TableProcessor::TableProcessor ( TimeSeriesTable  table)
inline

Use an in-memory TimeSeriesTable as the source table.

Since this constructor is not explicit, you can provide a TimeSeriesTable to any function that takes a TableProcessor (in C++).

◆ TableProcessor() [3/3]

OpenSim::TableProcessor::TableProcessor ( std::string  filepath)
inline

Use a filepath as the source table.

Since this constructor is not explicit, you can provide a string filepath to any function that takes a TableProcessor.

Member Function Documentation

◆ append() [1/2]

TableProcessor& OpenSim::TableProcessor::append ( const TableOperator op)
inline

Append an operation to the end of the operations in this processor.

◆ append() [2/2]

TableProcessor& OpenSim::TableProcessor::append ( const TableProcessor traj)
inline

Append all operations in another processor to this processor.

The source table of the provided trajectory is ignored.

References get_operators().

◆ append_operators()

int OpenSim::TableProcessor::append_operators ( const TableOperator value)
inline

Append an element to the operators property.

◆ clone()

TableProcessor* OpenSim::TableProcessor::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::Object.

◆ empty()

bool OpenSim::TableProcessor::empty ( ) const
inline

Returns true if neither a filepath nor an in-memory table have been provided.

◆ get_filepath()

const std::string& OpenSim::TableProcessor::get_filepath ( ) const
inline

Get the value of the filepath property.

◆ get_operators()

const TableOperator& OpenSim::TableProcessor::get_operators ( int  i) const
inline

Get the value of the i-th element of the operators property.

Referenced by append().

◆ getClassName()

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

This returns "TableProcessor".

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

◆ getConcreteClassName()

const std::string& OpenSim::TableProcessor::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::Object.

◆ operator|()

TableProcessor& OpenSim::TableProcessor::operator| ( const TableOperator right)
inline

This operator allows one to write the following code in C++:

TableProcessor proc = TableProcessor("file.sto") |
TabOpLowPassFilter(6);

◆ process() [1/2]

TimeSeriesTable OpenSim::TableProcessor::process ( std::string  relativeToDirectory,
const Model model = nullptr 
) const
inline

Process and obtain the table.

If a filepath is provided, it will be evaluated relative to relativeToDirectory. Certain TableOperators require a Model (e.g., TabOpConvertDegreesToRadians, TabOpUseAbsoluteStateNames). If this processor contains such an operator, then the operator will throw an exception if you do not provide a model when invoking this function.

◆ process() [2/2]

TimeSeriesTable OpenSim::TableProcessor::process ( const Model model = nullptr) const
inline

Same as above, but paths are evaluated with respect to the current working directory.

◆ processAndConvertToRadians() [1/2]

TimeSeriesTable OpenSim::TableProcessor::processAndConvertToRadians ( std::string  relativeToDirectory,
const Model model 
) const
inline

Same as process(), but the columns of processed table are converted from degrees to radians, if applicable.

This conversion requires a model.

References OpenSim::SimbodyEngine::convertDegreesToRadians(), OpenSim::Object::getName(), OpenSim::Model::getSimbodyEngine(), OpenSim::Component::hasSystem(), and OpenSim::TableUtilities::isInDegrees().

◆ processAndConvertToRadians() [2/2]

TimeSeriesTable OpenSim::TableProcessor::processAndConvertToRadians ( const Model model) const
inline

Same as above, but paths are evaluated with respect to the current working directory.

◆ safeDownCast()

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

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

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

◆ set_filepath()

void OpenSim::TableProcessor::set_filepath ( const std::string &  value)
inline

Set the value of the filepath property.

◆ set_operators()

void OpenSim::TableProcessor::set_operators ( int  i,
const TableOperator value 
)
inline

Set the value of the i-th element of operators property.

◆ upd_filepath()

std::string& OpenSim::TableProcessor::upd_filepath ( )
inline

Get a writable reference to the filepath property.

◆ upd_operators()

TableOperator& OpenSim::TableProcessor::upd_operators ( int  i)
inline

Get a writable reference to the i-th element of the operators property.

OpenSim Property, Socket, Output, Input Documentation

◆ filepath

std::string OpenSim::TableProcessor::filepath

"File path to a TimeSeriesTable."

This property appears in XML files under the tag <filepath>. This property was generated with the OpenSim_DECLARE_PROPERTY macro; see Property to learn about the property system.

get_filepath(), upd_filepath(), set_filepath()

◆ operators

TableOperator OpenSim::TableProcessor::operators

"Operators to apply to the source table of this processor."

This property appears in XML files under the tag <operators>. This property holds a list of objects, and was generated with the OpenSim_DECLARE_LIST_PROPERTY macro; see Property to learn about the property system.
