set_c

Description

set_c is an Integral Sequence Wrapper for set. As such, it shares all set 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 set.

Expression Semantics
set_c<T,c1,c2,... cn>
setn_c<T,c1,c2,... cn>
A set of integral constant wrappers integral_c<T,c1>, integral_c<T,c2>, ... integral_c<T,cn>; see Integral Sequence Wrapper.
set_c<T,c1,c2,... cn>::type
setn_c<T,c1,c2,... cn>::type
Identical to setn< integral_c<T,c1>, integral_c<T,c2>, ... integral_c<T,cn> >; see Integral Sequence Wrapper.
set_c<T,c1,c2,... cn>::value_type
setn_c<T,c1,c2,... cn>::value_type
Identical to T; see Integral Sequence Wrapper.

Example

typedef set_c< int,1,3,5,7,9 > odds;

BOOST_MPL_ASSERT_RELATION( size<odds>::value, ==, 5 );
BOOST_MPL_ASSERT_NOT(( empty<odds> ));

BOOST_MPL_ASSERT(( has_key< odds, integral_c<int,5> > ));
BOOST_MPL_ASSERT_NOT(( has_key< odds, integral_c<int,4> > ));
BOOST_MPL_ASSERT_NOT(( has_key< odds, integral_c<int,15> > ));
