Functions
template<typename it_src , typename it_dst >
void	copy_typecasting (it_src first, it_src last, it_dst target)
	Behaves like std::copy but allows the source and target iterators to be of different types through static typecasting.
template<typename src_container , typename dst_container >
void	copy_container_typecasting (const src_container &src, dst_container &trg)
	Copy all the elements in a container (vector, deque, list) into a different one performing the appropriate typecasting.

Function Documentation

template<typename src_container , typename dst_container >

void mrpt::utils::metaprogramming::copy_container_typecasting	(	const src_container &	src,
		dst_container &	trg
	)			[inline]

Copy all the elements in a container (vector, deque, list) into a different one performing the appropriate typecasting.

The target container is automatically resized to the appropriate size, and previous contents are lost. This can be used to assign std::vector's of different types:

   std::vector<int>    vi(10);
   std::vector<float>  vf;
   vf = vi;   // Compiler error
   mrpt::utils::metaprogramming::copy_container_typecasting(v1,vf);  // Ok

template<typename it_src , typename it_dst >

void mrpt::utils::metaprogramming::copy_typecasting	(	it_src	first,
		it_src	last,
		it_dst	target
	)			[inline]

Behaves like std::copy but allows the source and target iterators to be of different types through static typecasting.

Note:

As in std::copy, the target iterator must point to the first "slot" where to put the first transformed element, and sufficient space must be allocated in advance.
