CreateAnother()

template<typename TEquationContainer , unsigned int VDimension>

virtual::itk::LightObject::Pointer itk::LevelSetEvolution< TEquationContainer, MalcolmSparseLevelSetImage< VDimension > >::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::Object.

GetNameOfClass()
