mln::metal::const_< I >::ret* mln::internal::image_morpher< I, T, I::domain_t , cast_image_< T, I > >::delegatee_ (  )  const [inherited]

Return the delegatee_ pointer; default code.

I* mln::internal::image_morpher< I, T, I::domain_t , cast_image_< T, I > >::delegatee_ (  )  [inherited]

Return the delegatee_ pointer (non-const version); default code.

void mln::internal::image_base< T, I::domain_t , cast_image_< T, I > >::destroy (  )  [inherited]

Detach data from an image (free it if nobody else hold it).

const I ::domain_t& mln::internal::image_value_morpher< I, T, cast_image_< T, I > >::domain (  )  const [inherited]
bool mln::internal::image_value_morpher< I, T, cast_image_< T, I > >::has ( const typename I::psite &  p  )  const [inherited]

Hook to the image data.

const void* mln::internal::image_base< T, I::domain_t , cast_image_< T, I > >::id_ (  )  const [inherited]

Give an identifier of this image.

When several image variables designate the same image, they share the same identifier.

unsigned mln::internal::check::image_fastest_< cast_image_< T, I > , mln::metal::equal< mln_trait_image_speed(cast_image_< T, I >), trait::image::speed::fastest >::eval >::index_of_point ( const P &  p  )  const [inherited]

cast_image_< T, I > & mln::internal::image_morpher< I, T, I::domain_t , cast_image_< T, I > >::rw (  )  [inherited]

State that the morpher is writable.

This allows for C++ to use it as a mutable object even if it is a temporary object.
