vector_c

Description

vector_c is an Integral Sequence Wrapper for vector. As such, it shares all vector 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 vector.

Expression	Semantics
vector_cc₁,c₂,... c_n> vectorn_cc₁,c₂,... c_n>	A vector of integral constant wrappers `integral_c`c₁`>`, `integral_c`c₂`>`, ... `integral_c`c_n`>`; see Integral Sequence Wrapper.
vector_cc₁,c₂,... c_n>::type vectorn_cc₁,c₂,... c_n>::type	Identical to `vector`n`<` `integral_c`c₁`>`, `integral_c`c₂`>`, ... `integral_c`c_n`>` `>`; see Integral Sequence Wrapper.
vector_cc₁,c₂,... c_n>::value_type vectorn_cc₁,c₂,... c_n>::value_type	Identical to `T`; see Integral Sequence Wrapper.

Example

typedef vector_c fibonacci;
typedef push_backint_<55> >::type fibonacci2;

BOOST_MPL_ASSERT_RELATION( front::type::value, ==, 1 );
BOOST_MPL_ASSERT_RELATION( back::type::value, ==, 55 );
