get()

template<typename exp1 , int n>

auto vector_dist_expression_op< exp1, boost::mpl::int_< n >, VECT_COMP >::get ( const vect_dist_key_dx &  key ) const -> decltype(value(key))

inline

Return the result of the expression.

Note

this function must be deactivated on transitional objects. Suppose we are slicing a tensor of rank 2 an object of rank 1 is implicitly created for such object we have to deactivate this function because ill-formed

Parameters

key	point where to evaluate
