Detailed Description

UA_StatusCode wrapper class.

StatusCode can be used interchangeably with UA_StatusCode due to implicit conversions (without any overhead) but provides some methods to simplify the handling with status codes.

Constructor & Destructor Documentation

StatusCode() [1/2]

opcua::StatusCode::StatusCode ( )

constexprdefaultnoexcept

Create a StatusCode with the default status code UA_STATUSCODE_GOOD.

StatusCode() [2/2]

opcua::StatusCode::StatusCode ( UA_StatusCode code )

inlineconstexprnoexcept

Definition at line 51 of file types.hpp.

Member Function Documentation

get()

UA_StatusCode opcua::StatusCode::get ( ) const

inlineconstexprnoexcept

Explicitly get underlying UA_StatusCode.

Definition at line 55 of file types.hpp.

name()

std::string_view opcua::StatusCode::name ( ) const

inlinenoexcept

Get human-readable name of the StatusCode.

This feature might be disabled to create a smaller binary with the UA_ENABLE_STATUSCODE_DESCRIPTIONS build-flag. Then the function returns an empty string for every StatusCode.

Definition at line 63 of file types.hpp.

isGood()

bool opcua::StatusCode::isGood ( ) const

inlineconstexprnoexcept

Check if the status code is good.

Definition at line 68 of file types.hpp.

isUncertain()

bool opcua::StatusCode::isUncertain ( ) const

inlineconstexprnoexcept

Check if the status code is uncertain.

Definition at line 73 of file types.hpp.

isBad()

bool opcua::StatusCode::isBad ( ) const

inlineconstexprnoexcept

Check if the status code is bad.

Definition at line 78 of file types.hpp.

throwIfBad()

void opcua::StatusCode::throwIfBad ( ) const

inlineconstexpr

Throw a BadStatus exception if the status code is bad.
