iceoryx_hoofs/cxx/vector.hpp🔗

Namespaces🔗

Name
iox
building block to easily create free function for logging in a library context
iox::cxx

Classes🔗

Name
class iox::cxx::vector
C++11 compatible vector implementation. We needed to do some adjustments in the API since we do not use exceptions and we require a data structure which can be located fully in the shared memory.

Functions🔗

Name
template <typename T ,uint64_t CapacityLeft,uint64_t CapacityRight>
bool		 operator==(const iox::cxx::vector< T, CapacityLeft > & lhs, const iox::cxx::vector< T, CapacityRight > & rhs)
template <typename T ,uint64_t CapacityLeft,uint64_t CapacityRight>
bool		 operator!=(const iox::cxx::vector< T, CapacityLeft > & lhs, const iox::cxx::vector< T, CapacityRight > & rhs)

Functions Documentation🔗

function operator==🔗

template <typename T ,
uint64_t CapacityLeft,
uint64_t CapacityRight>
bool operator==(
    const iox::cxx::vector< T, CapacityLeft > & lhs,
    const iox::cxx::vector< T, CapacityRight > & rhs
)

function operator!=🔗

template <typename T ,
uint64_t CapacityLeft,
uint64_t CapacityRight>
bool operator!=(
    const iox::cxx::vector< T, CapacityLeft > & lhs,
    const iox::cxx::vector< T, CapacityRight > & rhs
)
