Detailed Description

template<typename T>
class Arp::System::Nm::Future< T >

Future object as proxy for return value an asynchronous function call

Constructor & Destructor Documentation

Future()

template<typename T >

Arp::System::Nm::Future< T >::Future ( )

default

Constructs an invalid Future

The default constructor is intended for Futures to be used as class members. Using copy or move constructors or assignments a class member can linked with a Promise.

Member Function Documentation

GetValue()

template<typename T >

T Arp::System::Nm::Future< T >::GetValue

(

void

)

const

Returns the value set by the associated Promise

This function may throws an exception if not value has been set. Use HasValue() to check it. If an exception was set by the Promise the exception is rethrown here.
