A condition (message, warning, or error) that occurred while orchestrating a future
While orchestrating (creating, launching, querying, collection) futures, unexpected run-time errors (and other types of conditions) may occur. Such conditions are coerced to a corresponding FutureCondition class to help distinguish them from conditions that occur due to the evaluation of the future.
FutureCondition(message, call = NULL, future = NULL)
FutureMessage(message, call = NULL, future = NULL)
FutureWarning(message, call = NULL, future = NULL)
FutureError(message, call = NULL, future = NULL)
UnexpectedFutureResultError(future, hint = NULL)
A message condition.
The call stack that led up to the condition.
The Future involved.
(optional) A string with a suggestion on what might be wrong.
An object of class FutureCondition which inherits from class condition and FutureMessage, FutureWarning, and FutureError all inherits from FutureCondition. Moreover, a FutureError inherits from error, a FutureWarning from warning, and a FutureMessage from message.
