FutureCondition {future} | R Documentation

## A condition (message, warning, or error) that occurred while orchestrating a future

### Description

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 FutureConditions class to help distinguish them from conditions that occur due to the evaluation of the future.

### Usage

    FutureCondition(message, call = NULL, future = NULL)

    FutureMessage(message, call = NULL, future = NULL)

    FutureWarning(message, call = NULL, future = NULL)

    FutureError(message, call = NULL, future = NULL, output = NULL)

### Arguments

`message` | A message.
`call` | The call stack that led up to the condition.
`future` | The Future involved.
`output` | (Don't use!) only for backward compatibility

### Value

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.
