Detailed Description

convert a type into constant type

this set of meta-functions traverse at compile time the tree-structure of types in Depth-first search. and transform any root node of type vector into vector_gpu_ker

Parameters

T	type tp convert

Returns

a constant of the type T

Consider

vector_gpu<aggregate<int,vector_gpu<aggregate<int,float>>>>

is a tree in this form
