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
enumerationto wrap.

Constructor & Destructor Documentation

template<typename E>
fsdk::Result< E >::Result ( error)
inlineexplicitnoexcept

Initializes result.

Parameters
[in]resultvalue 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.
