class negmas.situated.Contract(partners=<factory>, agreement=None, annotation=<factory>, issues=<factory>, signed_at=-1, executed_at=-1, concluded_at=-1, nullified_at=-1, to_be_signed_at=-1, signatures=<factory>, mechanism_state=None, mechanism_id=None, id=<factory>)[source]

Bases: object

A agreement definition which encapsulates an agreement with partners and extra information

Attributes Summary

`agreement`	The actual agreement of the negotiation in the form of an `Outcome` in the `Issue` space defined by `issues`
`concluded_at`	The time-step at which the contract was concluded (but it is still not binding until signed)
`executed_at`	The time-step at which the contract was executed/breached
`mechanism_id`	The Id of the mechanism that led to this contract
`mechanism_state`	The mechanism state at the contract conclusion
`nullified_at`	The time-step at which the contract was nullified after being signed.
`signed_at`	The time-step at which the contract was signed
`to_be_signed_at`	The time-step at which the contract should be signed

Attributes Documentation

agreement: Outcome | OutcomeSpace | None = None: The actual agreement of the negotiation in the form of an Outcome in the Issue space defined by issues

concluded_at: int = -1: The time-step at which the contract was concluded (but it is still not binding until signed)

executed_at: int = -1: The time-step at which the contract was executed/breached

mechanism_id: Optional[str] = None: The Id of the mechanism that led to this contract

mechanism_state: Optional[MechanismState] = None: The mechanism state at the contract conclusion

nullified_at: int = -1: The time-step at which the contract was nullified after being signed. That can happen if a partner declares bankruptcy

signed_at: int = -1: The time-step at which the contract was signed

to_be_signed_at: int = -1: The time-step at which the contract should be signed
