public CallStatus call() throws Exception
Operation
Operation.run()
methods will be replaced by call
methods.
The call method looks very much like the Operation.run()
method and it is
very close to Runnable.run()
and Callable.call()
.
The main difference between a run and call, is that the returned
CallStatus from the call can tell something about the actual execution.
For example it could tell that some waiting is required in case of a
BlockingOperation
. Or that the actual execution work is
offloaded to some executor in case of an
Offloadable
EntryOperation
.
In the future new types of CallStatus are expected to be added, e.g. for
interleaving.
In the future it is very likely that for regular Operation that want to
return a concrete response, the actual response can be returned directly.
In this case we'll change the return type to Object
to prevent
forcing the response to be wrapped in a CallStatus.DONE_RESPONSE
monad since that would force additional litter to be created.call

Exception
/Error
is thrown
during an invocation. Invocation process will continue, it will retry
or fail according to returned ExceptionAction
.
This method is called on caller side of the invocation.
