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,... c_n> setn_c<T,c₁,c₂,... c_n>	A set of integral constant wrappers `integral_c<T,`c₁`>`, `integral_c<T,`c₂`>`, ... `integral_c<T,`c_n`>`; see Integral Sequence Wrapper.
set_c<T,c₁,c₂,... c_n>::type setn_c<T,c₁,c₂,... c_n>::type	Identical to `set`n`<` `integral_c<T,`c₁`>`, `integral_c<T,`c₂`>`, ... `integral_c<T,`c_n`>` `>`; see Integral Sequence Wrapper.
set_c<T,c₁,c₂,... c_n>::value_type setn_c<T,c₁,c₂,... c_n>::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> > ));
