Member Function Documentation

bool PreProcessing::clear ( )

virtual

This is the main clear interface for all the GRT preprocessing modules. This should be overwritten by the derived class. It will completely clear the module, removing any IO values setting and all the base variables to their default values.

Returns: returns true if the derived class was cleared succesfully, false otherwise

Reimplemented from MLBase.

Reimplemented in FIRFilter.

Definition at line 85 of file PreProcessing.cpp.

bool PreProcessing::copyBaseVariables ( const PreProcessing * preProcessingModule )

This copies the PreProcessing variables from preProcessing to the instance that calls the function.

Parameters

preProcessing a pointer to a pre processing module from which the values will be copied

Returns: returns true if the copy was successfull, false otherwise

Definition at line 53 of file PreProcessing.cpp.

PreProcessing * PreProcessing::createInstanceFromString ( std::string const & preProcessingType )

static

This static function will dynamically create a new PreProcessing instance from a string.

Parameters

preProcessingType the name of the PreProcessing class you want to dynamically create

Returns: a pointer to the new PreProcessing instance that was created

Definition at line 29 of file PreProcessing.cpp.

PreProcessing * PreProcessing::createNewInstance ( ) const

This static function will dynamically create a new PreProcessing instance based on the type of this instance

Definition at line 159 of file PreProcessing.cpp.

virtual bool PreProcessing::deepCopyFrom ( const PreProcessing * rhs )

inlinevirtual

This is the base deepCopyFrom function for the PreProcessing modules. This function should be overwritten by the derived class.

Parameters

preProcessing a pointer to the PreProcessing base class, this should be pointing to another instance of a matching derived class

Returns: returns true if the deep copy was successfull, false otherwise (the PreProcessing base class will always return flase)

Reimplemented in Derivative, FIRFilter, LowPassFilter, HighPassFilter, SavitzkyGolayFilter, DeadZone, DoubleMovingAverageFilter, MedianFilter, MovingAverageFilter, WeightedAverageFilter, and LeakyIntegrator.

Definition at line 57 of file PreProcessing.h.

bool PreProcessing::getInitialized ( ) const

Returns true if the pre processing module has been initialized correctly.

Returns: returns true if the pre processing module has been initialized succesfully, false otherwise

Definition at line 175 of file PreProcessing.cpp.

UINT PreProcessing::getNumInputDimensions ( ) const

Returns the size of the input vector expected by the pre processing module.

Returns: returns the size of the input vector expected by the pre processing module

Definition at line 167 of file PreProcessing.cpp.

UINT PreProcessing::getNumOutputDimensions ( ) const

Returns the size of the vector that will be computed by the pre processing module.

Returns: returns the size of the vector that will be computed by the pre processing module

Definition at line 171 of file PreProcessing.cpp.

std::string PreProcessing::getPreProcessingType ( ) const

Returns: returns the pre processing type as a string, e.g. LowPassFilter

Definition at line 163 of file PreProcessing.cpp.

VectorFloat PreProcessing::getProcessedData ( ) const

Returns: returns a VectorFloat containing the most recent processed data

Definition at line 179 of file PreProcessing.cpp.

bool PreProcessing::init ( )

protected

Initializes the base preprocessing module, this will resize the processedData vector and get the instance ready for preprocessing new data. The inheriting class must first initialize the module before calling this function.

Returns: returns true if the module was initialized, false otherwise

Definition at line 93 of file PreProcessing.cpp.

bool PreProcessing::loadPreProcessingSettingsFromFile ( std::fstream & file )

protected

Loads the core preprocessing settings from a file.

Returns: returns true if the base settings were loaded, false otherwise

Definition at line 127 of file PreProcessing.cpp.

virtual bool PreProcessing::process ( const VectorFloat & inputVector )

inlinevirtual

This is the main processing interface for all the pre processing modules and should be overwritten by the inheriting class.

Parameters

inputVector a vector containing the data that should be processed

Returns: returns true if the pre processing was successfull, false otherwise

Reimplemented in Derivative, FIRFilter, LowPassFilter, HighPassFilter, SavitzkyGolayFilter, DeadZone, DoubleMovingAverageFilter, MedianFilter, MovingAverageFilter, WeightedAverageFilter, and LeakyIntegrator.

Definition at line 73 of file PreProcessing.h.

bool PreProcessing::reset ( )

virtual

This is the main reset interface for all the GRT preprocessing modules. This should be overwritten by the derived class.

Returns: returns true if the derived class was reset succesfully, false otherwise (the base class always returns true)

Reimplemented from MLBase.

Reimplemented in Derivative, FIRFilter, LowPassFilter, HighPassFilter, SavitzkyGolayFilter, DeadZone, DoubleMovingAverageFilter, MedianFilter, MovingAverageFilter, WeightedAverageFilter, and LeakyIntegrator.

bool PreProcessing::savePreProcessingSettingsToFile ( std::fstream & file ) const

protected

Saves the core preprocessing settings to a file.

Returns: returns true if the base settings were saved, false otherwise
