max
Synopsis
template<
typename N1
, typename N2
>
struct max
{
typedef |unspecified| type;
};
Description
Returns the larger of its two arguments.
Header
#include <boost/mpl/min_max.hpp>
Model of
Parameters
| Parameter | Requirement | Description |
|---|---|---|
| N1, N2 | Any type | Types to compare. |
Expression semantics
For arbitrary types x and y:
typedef max<x,y>::type r;
| Return type: | A type. |
|---|---|
| Precondition: | less<x,y>::value is a well-formed integral constant expression. |
| Semantics: | Equivalent to typedef if_< less<x,y>,y,x >::type r; |
Complexity
Constant time.
Example
typedef fold<
vector_c<int,1,7,0,-2,5,-1>
, int_<10>
, max<_1,_2>
>::type r;
BOOST_MPL_ASSERT(( is_same< r, int_<10> > ));
