class negmas.mechanisms.MechanismRoundResult(broken=False, timedout=False, agreement=None, error=False, error_details='', waiting=False, exceptions=None, times=None)[source]

Bases: object

Represents the results of a negotiation round (step). This is what round() should return.

Attributes Summary

`agreement`	The agreement if any.
`broken`	True only if END_NEGOTIATION was selected by one agent
`error`	True if an error occurred in the mechanism
`error_details`	Error message
`exceptions`	A mapping from negotiator ID to a list of exceptions raised by that negotiator in this round
`timedout`	True if a timeout occurred.
`times`	A mapping from negotiator ID to the time it consumed during this round
`waiting`	whether to consider that the round is still running and call the round method again without increasing the step number
