Detailed Description

template<typename T>
class RCF::Future< T >

Provides the ability for remote calls to be executed asynchronously.

The Future class provides the user with a mechanism to access the return values of an asynchronous remote call. Future instances can be used as parameters or return values in a remote call. If any Future instances are used in a remote call invocation, the remote call is performed asynchronously. There are several ways of waiting for an asynchronous remote call to complete. You can poll a Future instance using ready(), or wait for a specified time interval using wait(). You can also cancel the call at any time using cancel(). Once a remote call completes, the result is accessed by dereferencing the Future instance using operator*(). The Future class is internally reference counted, and has shallow copy semantics.

Constructor & Destructor Documentation

Future() [1/2]

template<typename T>

RCF::Future< T >::Future

(

)

Constructs a new Future instance.

Future() [2/2]

template<typename T>

RCF::Future< T >::Future

(

const T &

t

)

Constructs a new Future instance, holding a copy of t.

Member Function Documentation

operator*()

template<typename T>

T& RCF::Future< T >::operator*

(

)

Dereferences this Future instance. If the remote call is still in progress, this function will block until the remote call completes.

ready()

template<typename T>

bool RCF::Future< T >::ready

(

)

Tests whether the result of an asynchronous call is ready.

wait()

template<typename T>

void RCF::Future< T >::wait

(

std::uint32_t

timeoutMs = 0

)

Waits for up to timeoutMs ms, for the result of an asynchronous call to become ready.

cancel()

template<typename T>

void RCF::Future< T >::cancel

(

)

Cancels an asynchronous call.

clear()

template<typename T>

void RCF::Future< T >::clear

(

)

Clears this Future instance.
