g fdZddlZGddeZGddeZGddej Zy) a|A Future interface. Python doesn't have a Future interface in its standard library. In the absence of such a standard, three separate, incompatible implementations (concurrent.futures.Future, ndb.Future, and asyncio.Future) have appeared. This interface attempts to be as compatible as possible with concurrent.futures.Future. From ndb.Future it adopts a traceback-object accessor method. Unlike the concrete and implemented Future classes listed above, the Future class defined in this module is an entirely abstract interface that anyone may implement and use. The one known incompatibility between this interface and the interface of concurrent.futures.Future is that this interface defines its own CancelledError and TimeoutError exceptions rather than raising the implementation-private concurrent.futures._base.CancelledError and the built-in-but-only-in-3.3-and-later TimeoutError.

Computations represented by a Future may be yet to be begun, may be ongoing, or may have already completed. ct)aAttempts to cancel the computation. This method does not block. Returns: True if the computation has not yet begun, will not be allowed to take place, and determination of both was possible without blocking. False under all other circumstances including but not limited to the computation's already having begun, the computation's already having finished, and the computation's having been scheduled for execution on a remote system for which a determination of whether or not it commenced before being cancelled cannot be made without blocking. NotImplementedErrorselfs r cancelz Future.cancel>s "##r ct)aDescribes whether the computation was cancelled. This method does not block. Returns: True if the computation was cancelled any time before its result became immediately available. False under all other circumstances including but not limited to this object's cancel method not having been called and the computation's result having become immediately available. rrs r cancelledzFuture.cancelled]s "##r ct)a2Describes whether the computation is taking place. This method does not block. Returns: True if the computation is scheduled to take place in the future or is taking place now, or False if the computation took place in the past or was cancelled. rrs r runningzFuture.runningk "##r ct)aIDescribes whether the computation has taken place. This method does not block. Returns: True if the computation is known to have either completed or have been unscheduled or interrupted. False if the computation may possibly be executing or scheduled to execute later. rrs r donez Future.done|rr Nct)a Accesses the outcome of the computation or raises its exception. This method may return immediately or may block. Args: timeout: The length of time in seconds to wait for the computation to finish or be cancelled, or None if this method should block until the computation has finished or is cancelled no matter how long that takes. Returns: The return value of the computation. Raises: TimeoutError: If a timeout value is passed and the computation does not terminate within the allotted time. CancelledError: If the computation was cancelled. Exception: If the computation raised an exception, this call will raise the same exception. rrtimeouts r resultz Future.result *"##r ct)aReturn the exception raised by the computation. This method may return immediately or may block. Args: timeout: The length of time in seconds to wait for the computation to terminate or be cancelled, or None if this method should block until the computation is terminated or is cancelled no matter how long that takes. Returns: The exception raised by the computation, or None if the computation did not raise an exception. Raises: TimeoutError: If a timeout value is passed and the computation does not terminate within the allotted time. CancelledError: If the computation was cancelled. rrs r exceptionzFuture.exceptionr"r ct)aAccess the traceback of the exception raised by the computation. This method may return immediately or may block. Args: timeout: The length of time in seconds to wait for the computation to terminate or be cancelled, or None if this method should block until the computation is terminated or is cancelled no matter how long that takes. Returns: The traceback of the exception raised by the computation, or None if the computation did not raise an exception. Raises: TimeoutError: If a timeout value is passed and the computation does not terminate within the allotted time. CancelledError: If the computation was cancelled. rrs r tracebackzFuture.tracebackr"r ct)aqAdds a function to be called at completion of the computation.
