Detailed Description

Abstract base interface for asynchronous consumers.

Provides a common, type-erased interface for accessing asynchronous results, regardless of their actual type or ownership semantics.

Key methods include:

• valid() : check if the consumer is valid
• ready() : check if the result is ready
• wait() : block until ready
• waitFor() : Block with a timeout
• exception(): retrieve any stored exception

Member Function Documentation

exception()

virtual std::exception_ptr original::async::futureBase::exception ( ) const

pure virtualnoexcept

Gets the stored exception if computation failed.

Returns

Exception pointer (nullptr if no exception)

Implemented in original::async::future< TYPE >, original::async::sharedFuture< TYPE >, original::async::future< void >, and original::async::sharedFuture< void >.

ready()

virtual bool original::async::futureBase::ready ( ) const

pure virtual

Checks if the result is ready.

Returns

True if result is available

Implemented in original::async::future< TYPE >, original::async::sharedFuture< TYPE >, original::async::future< void >, and original::async::sharedFuture< void >.

valid()

virtual bool original::async::futureBase::valid ( ) const

pure virtualnoexcept

Checks if the future is valid (has an associated async wrapper)

Returns

True if valid, false otherwise

Implemented in original::async::future< TYPE >, original::async::sharedFuture< TYPE >, original::async::future< void >, and original::async::sharedFuture< void >.

wait()

virtual void original::async::futureBase::wait ( ) const

pure virtual

Waits until the result becomes ready.

Implemented in original::async::future< TYPE >, original::async::sharedFuture< TYPE >, original::async::future< void >, and original::async::sharedFuture< void >.

waitFor()

virtual bool original::async::futureBase::waitFor ( time::duration  timeout ) const

pure virtual

Waits for the result with a timeout.

Parameters

timeout

Maximum time to wait

Returns

True if result is ready within timeout, false otherwise

Implemented in original::async::future< TYPE >, original::async::sharedFuture< TYPE >, original::async::future< void >, and original::async::sharedFuture< void >.
