Detailed Description

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

A class used to instantiate and generate function objects of templated member functions with two template arguments.

Template Parameters

TMemberFunctionPointer is the type of pointer to member function

Example member function and pointer:

type alias Image::Pointer (Self::*MemberFunctionType)( Image::Pointer );
 
template<typename TImageType1, TImageType2>
Image::Pointer ExecuteInternal( Image::Pointer );

The provided Addressor will instantiate the templeted member functions by taking the address in the RegisterMethods. Later they can be retrieve with the GetMemberFunction method, which returns 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.

Warning: Use this class with caution because it can instantiate a combinatorial number of methods.

Constructor & Destructor Documentation

◆ DualMemberFunctionFactory()

template<typename TMemberFunctionPointer >

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

Constructor which permanently binds the constructed object to pObject.

Member Function Documentation

◆ GetMemberFunction()

template<typename TMemberFunctionPointer >

FunctionObjectType itk::simple::detail::DualMemberFunctionFactory< TMemberFunctionPointer >::GetMemberFunction	(	PixelIDValueType	pixelID1,
		PixelIDValueType	pixelID2,
		unsigned int	imageDimension
	)

Returns a function object for the combination of PixelID1 and PixelID2, and image dimension.

pixelID1 or pixelID2 is the value of Image::GetPixelIDValue(), or PixelIDToPixelIDValue<PixelIDType>::Result

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

Example usage:

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

◆ HasMemberFunction()

template<typename TMemberFunctionPointer >

bool itk::simple::detail::DualMemberFunctionFactory< TMemberFunctionPointer >::HasMemberFunction	(	PixelIDValueType	pixelID1,
		PixelIDValueType	pixelID2,
		unsigned int	imageDimension
	)		const

noexcept

Query to determine if an member function has been registered for pixelID1, pixelID2 and imageDimension.

◆ Register()

template<typename TMemberFunctionPointer >

template<typename TImageType1 , typename TImageType2 >

void itk::simple::detail::DualMemberFunctionFactory< TMemberFunctionPointer >::Register	(	MemberFunctionType	pfunc,
		TImageType1 *	,
		TImageType2 *
	)

Registers a specific member function.

Registers a member function templated over TImageType1 and TImageType2

◆ RegisterMemberFunctions() [1/2]

template<typename TMemberFunctionPointer >

template<typename TPixelIDTypeList1 , typename TPixelIDTypeList2 , unsigned int VImageDimension, typename TAddressor >

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

Registers the member functions for all combinations of TPixelIDTypeList1 and PixelIDTypeList2.

With out the third template argument, the DualExecuteInternalAddressor will be used to instantiate "DualExecuteInternal" methods over the two image types referenced by all combination of type in the first list with types in the second.

The optional third template parameter provides a custom addressor.

Example usage:

this->m_MemberFactory->RegisterMemberFunctions< PixelIDTypeList1,

PixelIDTypeList2, 3 > ();

or if a custom addressor is needed:

template < class TMemberFunctionPointer >
   struct MyCustomAddressor
   {
     using ObjectType = typename ::detail::FunctionTraits<TMemberFunctionPointer>::ClassType;
 
     template< typename TImageType1, typename TImageType2 >
     TMemberFunctionPointer operator() ( void ) const
     {
       return &ObjectType::template CustomMethod< TImageType1, TImageType2 >;
     }
   };
 
this->m_MemberFactory->RegisterMemberFunctions< PixelIDTypeList1,
                                                PixelIDTypeList2,
                                                3,
                                                MyCustomAddressor<TMFP> > ();

◆ RegisterMemberFunctions() [2/2]

template<typename TMemberFunctionPointer >

template<typename TPixelIDTypeList1 , typename TPixelIDTypeList2 , unsigned int VImageDimension>

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

inline

Registers the member functions for all combinations of TPixelIDTypeList1 and PixelIDTypeList2.

With out the third template argument, the DualExecuteInternalAddressor will be used to instantiate "DualExecuteInternal" methods over the two image types referenced by all combination of type in the first list with types in the second.

The optional third template parameter provides a custom addressor.

Example usage:

this->m_MemberFactory->RegisterMemberFunctions< PixelIDTypeList1,

PixelIDTypeList2, 3 > ();

or if a custom addressor is needed:

template < class TMemberFunctionPointer >
   struct MyCustomAddressor
   {
     using ObjectType = typename ::detail::FunctionTraits<TMemberFunctionPointer>::ClassType;
 
     template< typename TImageType1, typename TImageType2 >
     TMemberFunctionPointer operator() ( void ) const
     {
       return &ObjectType::template CustomMethod< TImageType1, TImageType2 >;
     }
   };
 
this->m_MemberFactory->RegisterMemberFunctions< PixelIDTypeList1,
                                                PixelIDTypeList2,
                                                3,
                                                MyCustomAddressor<TMFP> > ();
