This overload prevents the bool() operator above from participating in dangerous implicit conversion chains such as bool->int, bool->int->float, bool->int->double.

Detailed Description

template<typename E>
struct fsdk::Result< E >

A structure that encapsulates an action result enumeration.

An enum should specify a result code. By default the result is in a special uninitialized state which should be interpreted as an error. Default success value shoud be defined to zero.

Template Parameters

enumeration

to wrap.

Constructor & Destructor Documentation

template<typename E>

fsdk::Result< E >::Result ( E  error )

inlineexplicitnoexcept

Initializes result.

Parameters

[in]

result

value to set.

Member Function Documentation

template<typename E>

E fsdk::Result< E >::getError ( ) const

inlinenoexcept

Gets actual result value.

Returns

actual result value.

template<typename E>

bool fsdk::Result< E >::isError ( ) const

inlinenoexcept

Checks for an error.

Returns

true if result represents an error.

template<typename E>

bool fsdk::Result< E >::isOk ( ) const

inlinenoexcept

Checks for a success.

Returns

true if result represents a success.

template<typename E>

fsdk::Result< E >::operator bool ( ) const

inlinenoexcept

Checks for a success.

Returns

true if result represents a success.

template<typename E>

const char* fsdk::Result< E >::what ( ) const

inlinenoexcept

Gets a textual description of the result.

Note

function toString() should be specialized for this template type T.

Returns

description string.
