from_core()

ErrorCode bm::ErrorCodeMap::from_core

(

const Core &

core

)

const

Retrieve an error code for one of the core errors.

from_name()

ErrorCode bm::ErrorCodeMap::from_name

(

const std::string &

name

)

const

Retrieve an error code from a P4 error name. Will throw std::out_of_range exception if name does not exist.

to_name()

const std::string& bm::ErrorCodeMap::to_name

(

const ErrorCode &

code

)

const

Retrieve an error code's name. Will throw std::out_of_range exception if the error code is not valid.
