Member Function Documentation

CreateAnother()

template<typename TInput = float, typename TOutput = double>

virtual::itk::LightObject::Pointer itk::AtanRegularizedHeavisideStepFunction< TInput, TOutput >::CreateAnother ( ) const

virtual

Create an object from an instance, potentially deferring to a factory. This method allows you to create an instance of an object that is exactly the same type as the referring object. This is useful in cases where an object has been cast back to a base class.

Reimplemented from itk::LightObject.

Evaluate()

template<typename TInput = float, typename TOutput = double>

OutputType itk::AtanRegularizedHeavisideStepFunction< TInput, TOutput >::Evaluate ( const InputType & input ) const

overridevirtual

Evaluate at the specified input position

Implements itk::HeavisideStepFunctionBase< float, double >.

EvaluateDerivative()

template<typename TInput = float, typename TOutput = double>

OutputType itk::AtanRegularizedHeavisideStepFunction< TInput, TOutput >::EvaluateDerivative ( const InputType & input ) const

overridevirtual

Evaluate the derivative at the specified input position

Implements itk::HeavisideStepFunctionBase< float, double >.

GetNameOfClass()

template<typename TInput = float, typename TOutput = double>

const char * itk::AtanRegularizedHeavisideStepFunction< TInput, TOutput >::GetNameOfClass ( ) const

overridevirtual

Return the name of this class as a string. Used by the object factory (implemented in New()) to instantiate objects of a named type. Also used for debugging and other output information.

Reimplemented from itk::LightObject.
