google.appengine.ext.ndb.Future

A Future has 0 or more callbacks.

Inherits From: expected_type

google.appengine.ext.ndb.Future(
    info=None
)

The callbacks will be called when the result is ready.

NOTE: This is somewhat inspired but not conformant to the Future interface defined by PEP 3148. It is also inspired (and tries to be somewhat compatible with) the App Engine specific UserRPC and MultiRpc classes.
