effective procedure
Assign ios witht the value of a_io
require
  • a_io.is_connected
ensure
prepare (a_events: EVENTS_SET)
effective procedure
Launched before starting the to manage requests.
Indicate in a_events the kind of request to manage.
require
  • a_events /= Void
  • not a_events.queryable
  • not done
is_ready (a_events: EVENTS_SET): BOOLEAN
effective function
True if Current is ready to manage requests using a_events to detect it.
require
  • a_events /= Void
  • a_events.queryable
  • not done
done: BOOLEAN
effective function
Current has finished managing requests and answers.
restart
effective procedure
Restart the connection.
Require by Job. Should not be used.
require
  • done
ensure
  • not done
writable attribute
{}
Used to read (request) and write (answer)
priority: INTEGER_32
writable attribute
never change a job's priority after inserting it in loop_item.
Priority should only be set at creation time.
continue
deferred procedure
Continue to do the job.
The work to do has to be small work and non blocking, it will continue on next call.
require
infix "<" (other: JOB): BOOLEAN
