Detailed Description

template<typename TInput = float, typename TOutput = double>
class itk::HeavisideStepFunction< TInput, TOutput >

Member Function Documentation

template<typename TInput = float, typename TOutput = double>
virtual::itk::LightObject::Pointer itk::HeavisideStepFunction< TInput, TOutput >::CreateAnother ( void  ) 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::Object.

template<typename TInput = float, typename TOutput = double>
OutputType itk::HeavisideStepFunction< TInput, TOutput >::Evaluate ( const InputType input) const [virtual]

Evaluate at the specified input position

Implements itk::HeavisideStepFunctionBase< TInput, TOutput >.

template<typename TInput = float, typename TOutput = double>
OutputType itk::HeavisideStepFunction< TInput, TOutput >::EvaluateDerivative ( const InputType input) const [virtual]

Evaluate the derivative at the specified input position

Implements itk::HeavisideStepFunctionBase< TInput, TOutput >.

template<typename TInput = float, typename TOutput = double>
virtual const char* itk::HeavisideStepFunction< TInput, TOutput >::GetNameOfClass ( ) const [virtual]

Run-time type information

Reimplemented from itk::HeavisideStepFunctionBase< TInput, TOutput >.

template<typename TInput = float, typename TOutput = double>
static Pointer itk::HeavisideStepFunction< TInput, TOutput >::New ( ) [static]

Method for creation through the object factory.

Reimplemented from itk::Object.

template<typename TInput = float, typename TOutput = double>
void itk::HeavisideStepFunction< TInput, TOutput >::operator= ( const Self ) [private]
