- STYLE: Add itkVirtualGetNameOfClassMacro + itkOverrideGetNameOfClassMacro
- STYLE: Replace itkStaticConstMacro with static constexpr
- STYLE: CoordRepType -> CoordinateType code readability
…acro Added two new macro's, intended to replace the old 'itkTypeMacro' and 'itkTypeMacroNoParent'. The main aim is to be clearer about what those macro's do: add a virtual 'GetNameOfClass()' member function and override it. Unlike 'itkTypeMacro', 'itkOverrideGetNameOfClassMacro' does not have a 'superclass' parameter, as it was not used anyway. Note that originally 'itkTypeMacro' did not use its 'superclass' parameter either, looking at commit 699b66cb04d410e555656828e8892107add38ccb, Will Schroeder, June 27, 2001: https://github.com/InsightSoftwareConsortium/ITK/blob/699b66cb04d410e555656828e8892107add38ccb/Code/Common/itkMacro.h#L331-L337
Use static constexpr directly now that C++11 conformance is required by all compilers. :%s/itkStaticConstMacro *( *\([^,]*\),[ \_s]*\([^,]*\),\_s*\([^)]*\)) */static constexpr \2 \1 = \3/ge 'itkStaticConstMacro(name, type, value)' became unconditionally identical to 'static constexpr type name = value' with ITK commit aec95193ab00e1322039911e1032da00f3a103b6 "ENH: Update compiler macros (#810)", maekclena, 7 May 2019. 'itkGetStaticConstMacro(name)' became unconditionally identical to '(Self::name)' with ITK commit 84e490b81e3f3c2b0edb89ae7b9de53bfc52f2b2 "Removing some outdated compiler conditionals", Hans Johnson, 31 July 2010. Most 'itkStaticConstMacro' calls were removed by ITK commit 5c14741e1e063a132ea7e7ee69c5bd0a4e49af74
For the sake of code readability, a new 'CoordinateType' alias is added for each nested 'CoordRepType' alias. The old 'CoordRepType' aliases will still be available with ITK 6.0, but it is recommended to use 'CoordinateType' instead. The 'CoordRepType' aliases will be removed when 'ITK_FUTURE_LEGACY_REMOVE' is enabled. Similarly, 'InputCoordinateType', 'OutputCoordinateType', and 'ImagePointCoordinateType' replace 'InputCoordRepType', 'OutputCoordRepType', and 'ImagePointCoordRepType', respectively.
