An analyzer can be applied on an activity to analyze its result data. The analyzer can be equipped with callbackss to handle different result states.

construct an analyzer

self_type &incomplete(incomplete_ftor_type ftor)

If the activity is incomplete and an incomplete callback is set then the incomplete callback is invoked if any of the following holds

• there is no error callback

• there is an error callback but the task has not been canceled

• there is an error callback and the task has been canceled (

  See

  operator()(const success_type&, const failure_type&))

self_type &canceled(cancelation_ftor_type ftor)

If the activity is canceled and a canceled callback is set then the canceled callback is invoked if the following holds

• there is no error callback

self_type &error(success_ftor_type ftor)

The error callback is called if the subtask has not failed but has been canceled (through cancel_if) Once the error callback is set failure and incomplete callbacks are invoked differently The error callback is called if the following holds

• there is an error callback set and the activity is canceled and the activity has not failed

self_type &failure(failure_ftor_type ftor)

If the activity has failed and afailure callback is set then the failure callback is called if any of the following holds

• there is no error callback

• there is an error callback set and the activity is canceled

• there is an error callback set and the activity is not canceled

self_type &success(success_ftor_type ftor)

If the activity is complete and neither failed nor canceled then the success callback is called if a a success callback is set
