list_c

Description

list_c is an Integral Sequence Wrapper for list. As such, it shares all list characteristics and requirements, and differs only in the way the original sequence content is specified.

Expression semantics

The semantics of an expression are defined only where they differ from, or are not defined in list.

Expression Semantics
list_c<T,c1,c2,... cn>
listn_c<T,c1,c2,... cn>
A list of integral constant wrappers integral_c<T,c1>, integral_c<T,c2>, ... integral_c<T,cn>; see Integral Sequence Wrapper.
list_c<T,c1,c2,... cn>::type
listn_c<T,c1,c2,... cn>::type
Identical to listn< integral_c<T,c1>, integral_c<T,c2>, ... integral_c<T,cn> >; see Integral Sequence Wrapper.
list_c<T,c1,c2,... cn>::value_type
listn_c<T,c1,c2,... cn>::value_type
Identical to T; see Integral Sequence Wrapper.

Example

typedef list_c<int,1,2,3,5,7,12,19,31> fibonacci;
typedef push_front<fibonacci,int_<1> >::type fibonacci2;

BOOST_MPL_ASSERT_RELATION( front<fibonacci2>::type::value, ==, 1 );
