Destroys a future object.
If this is the last reference to the asynchronous result associated with *this (if any), then destroy that asynchronous result.

| ONIXS_FIXENGINE_API bool hasException | ( | ) | const |
Returns true if the asynchronous result associated with this Future has a stored exception, false otherwise.
| The | std::logic_error if this instance does not refer to a shared state. |
| ONIXS_FIXENGINE_API bool hasValue | ( | ) | const |
Returns true if the asynchronous result associated with this Future has a stored value, false otherwise.
| The | std::logic_error if this instance does not refer to a shared state. |
| ONIXS_FIXENGINE_API bool isReady | ( | ) | const |
Returns true if the asynchronous result associated with this Future is ready (has a value or an exception stored in the shared state), false otherwise.
There are often situations where a get() call on a Future may not be a blocking call, or is only a blocking call under certain circumstances. This method gives the ability to test for early completion and allows us to avoid associating a continuation, which needs to be scheduled with some non-trivial overhead and near-certain loss of the cache efficiency.

| ONIXS_FIXENGINE_API FutureStatus::Enum wait | ( | int | timeoutInMs = InfiniteTimeout | ) | const |
Waits for the result to become available during the timeout.
wait on the same Future from multiple threads is not safe; the intended use is for each thread that waits on the same shared state to have a copy of a Future.| The | std::logic_error if this instance does not refer to a shared state. |
