[Insight-users] Source code for itkOptimizer->GetCurrentPosition()

[Neil Weisenfeld]

Vanilla cases of Get and Set of class member variables are often created 
using macros to avoid having to repeatedly code things like:

const ParametersType& GetCurrentPosition() { return 
this->m_CurrentPosition; };

So in itkOptimizer.h you see:

   /** Get current position of the optimization. */
   itkGetConstReferenceMacro( CurrentPosition, ParametersType );

and the macro is defined in Code/Common/itkMacro.h as:

#define itkGetConstReferenceMacro(name,type) \
   virtual const type & Get##name () const \
   { \
     itkDebugMacro("returning " << #name " of " << this->m_##name ); \
     return this->m_##name; \
   }

which generates a definition for GetCurrentPosition.


HTH,
Neil


p.s. -- it's 2:30am, so someone will bark if I made any mistakes and 
please excuse them.
