FutureValue

trait FutureValue extends AnyRef

Common trait for all classes that exhibit a future-like behavior. That is, they contain a value that may not yet have been computed, and that may still throw exceptions. But unlike for Future, no methods are provided for extracting that value, only to wait for it.

Abstract Value Members

  1. abstract def await: Unit

    Blocks until this future value is computed.

    Blocks until this future value is computed. (Or throws an exception if the computation fails.)

  2. abstract def someFuture: Future[Any]

    Returns a future that completes when the computation of this object is complete.

    Returns a future that completes when the computation of this object is complete. (Or that holds an exception if that computation throws an exception.) However, upon successful completion, the future may return an arbitrary (and thus useless) value. May be faster to implement than forceFuture because there may be already a future available but that returns the wrong value.

  8. def force: FutureValue.this.type

    Waits till the computation of this value (in the Isabelle process) has finished.

    Waits till the computation of this value (in the Isabelle process) has finished. (Or until an exception is thrown.)

    returns

    this value, but it is guaranteed to have completed the computation

  9. def forceFuture(implicit ec: ExecutionContext): Future[FutureValue.this.type]

    A future containing this object with the computation completed.

    A future containing this object with the computation completed. In particular, if this value throws an exception upon computation, the future holds that exception.

    Roughly the same as Future { this.force }.

  16. def stateString: String

    A utility method that returns "" if this value was successfully computed, " (computing)" if it still computes, and " (failed)" if it finished with an exception.

    A utility method that returns "" if this value was successfully computed, " (computing)" if it still computes, and " (failed)" if it finished with an exception.

    This can be useful to constructing human readable messages about this value.
