template<typename I, typename F>

const F & mln::extension_fun< I, F >::extension

(

)

const [inline]

Give the extension function.

template<typename I, typename F>

template<typename P>

bool mln::extension_fun< I, F >::has

(

const P &

p

)

const [inline]

Test if p is valid.

It returns always true, assuming that the function is valid for any p.

internal::morpher_lvalue_< I >::ret mln::extension_fun< I, F >::operator()

(

const typename I::psite &

p

)

[inline]

Read-write access to the image value located at site p.

template<typename I, typename F>

I::value mln::extension_fun< I, F >::operator()

(

const typename I::psite &

p

)

const [inline]

Read-only access to the image value located at site p;.
