Initializes the instance with shared state.
◆ FutureBase() [4/4]
Initializes the instance with shared state.
◆ ~FutureBase()
Destroys a future object.
If this is the last reference to the asynchronous result associated with *this (if any), then destroy that asynchronous result.

Returns true if the asynchronous result associated with this Future has a stored value, false otherwise.

◆ is_ready()
| ONIXS_CBOE_CFE_BOE_API bool is_ready |

Returns true if the asynchronous result associated with this Future is ready (has a value or 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 cache efficiency.

◆ valid()
Check if a future instance is associated with an asynchronous result.
Returns true if the *this has an associated asynchronous result, false otherwise.

◆ wait()
Waits for the result to become available during the timeout.
- Note
- Calling
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.
