Detailed Description

template<typename TMemberFunctionPointer>
class itk::simple::detail::MemberFunctionFactory< TMemberFunctionPointer >

A class used to instantiate and generate function object to templated member functions.

Template Parameters

TMemberFunctionPointer is the type of pointer to member function

Example member function pointer:

typedef Self& (Self::*MemberFunctionType)( Image* );

The RegisterMemberFunctions instantiate the templeted member functions and registers the member function pointer, so that it be used for dispatch later. Later they can be retrieve with the GetMemberFunction methods, which return a function object with the same arguments as the templated member function pointer.

An instance of a MemberFunctionFactory is bound to a specific instance of an object, so that the returned function object does not need to have the calling object specified.

Constructor & Destructor Documentation

template<typename TMemberFunctionPointer>

itk::simple::detail::MemberFunctionFactory< TMemberFunctionPointer >::MemberFunctionFactory ( ObjectType * pObject )

Constructor which permanently binds the constructed object to pObject.

Member Function Documentation

template<typename TMemberFunctionPointer>

FunctionObjectType itk::simple::detail::MemberFunctionFactory< TMemberFunctionPointer >::GetMemberFunction	(	PixelIDValueType	pixelID,
		unsigned int	imageDimension
	)

Returns a function object for the PixelIndex, and image dimension.

pixelID is the value of Image::GetPixelIDValue(), or PixelIDToPixelIDValue<PixelIDType>::Result

imageDimension is the the value returned by Image::GetDimension()

Example usage:

PixelIDValueType pixelID = image->GetPixelIDValue();
unsigned int dimension = image->GetDimension();
return this->m_MemberFactory->GetMemberFunction( pixelID, dimension )( image );

If the requested member function is not registered then an exception is generated. The returned function object is guaranteed to be valid.

template<typename TMemberFunctionPointer>

bool itk::simple::detail::MemberFunctionFactory< TMemberFunctionPointer >::HasMemberFunction	(	PixelIDValueType	pixelID,
		unsigned int	imageDimension
	)		const
throw	(
	)

Query to determine if an member function has been registered for pixelID and imageDimension.

template<typename TMemberFunctionPointer>

template<typename TImageType >

void itk::simple::detail::MemberFunctionFactory< TMemberFunctionPointer >::Register	(	MemberFunctionType	pfunc,
		TImageType *
	)

Registers a specific member function.

Registers a member function which will be dispatched to the TImageType type

template<typename TMemberFunctionPointer>

template<typename TPixelIDTypeList , unsigned int VImageDimension, typename TAddressor >

void itk::simple::detail::MemberFunctionFactory< TMemberFunctionPointer >::RegisterMemberFunctions ( void )

Registers all member functions in TPixelIDTypeList and simple::InstantiatedPixelIDTypeList over itk::Image<Pixel, ImageDimension>

Template Parameters

TAddressor is the type of a class who as a templated operator() which returns TMemberFunctionPointer, this will default to detail::MemberFunctionAddressor if not specified

Example usage:

template < class TMemberFunctionPointer >
struct AllocateAddressor
{
  typedef typename ::detail::FunctionTraits<TMemberFunctionPointer>::ClassType ObjectType;
  template< typename TImageType >
  TMemberFunctionPointer operator() ( void ) const
    {
      return &ObjectType::template AllocateInternal< TImageType >;
    }
};
this->m_MemberFunctionFactory->RegisterMemberFunctions<PixelIDTypeList,
                                                       3,
                                                       AllocateAddressor<TMFP> > ();

Example usage:

this->m_MemberFactory->RegisterMemberFunctions< PixelIDTypeList, 3 > ();

this->m_MemberFactory->RegisterMemberFunctions< PixelIDTypeList, 2 > ();

template<typename TMemberFunctionPointer>

template<typename TPixelIDTypeList , unsigned int VImageDimension>

void itk::simple::detail::MemberFunctionFactory< TMemberFunctionPointer >::RegisterMemberFunctions ( void )

inline

Registers all member functions in TPixelIDTypeList and simple::InstantiatedPixelIDTypeList over itk::Image<Pixel, ImageDimension>

Template Parameters

TAddressor is the type of a class who as a templated operator() which returns TMemberFunctionPointer, this will default to detail::MemberFunctionAddressor if not specified

Example usage:

template < class TMemberFunctionPointer >
struct AllocateAddressor
{

  template< typename TImageType >
  TMemberFunctionPointer operator() ( void ) const
    {
      return &ObjectType::template AllocateInternal< TImageType >;
    }
};
this->m_MemberFunctionFactory->RegisterMemberFunctions<PixelIDTypeList,
                                                       3,
                                                       AllocateAddressor<TMFP> > ();
