nexosim.exceptions

Simulation-related exceptions.

All exceptions derive from the SimulationError class.

`SimulationError`

Bases: Exception

The base class for exceptions thrown by a Simulation.

`MissingArgumentError`

Bases: SimulationError

Raised when a simulation call was invoked with too few arguments.

`InvalidTimeError`

Bases: SimulationError

Raised when the provided timestamp is not well-formed.

`InvalidPeriodError`

Bases: SimulationError

Raised when a null or negative period was provided.

`InvalidDeadlineError`

Bases: SimulationError

Raised when a deadline that is not in the future of the current simulation time was provided.

`InvalidMessageError`

Bases: SimulationError

Raised when the provided event, query or initialization configuration message is invalid.

`InvalidKeyError`

Bases: SimulationError

Raised when an event key is invalid or outdated.

`SimulationNotStartedError`

Bases: SimulationError

Raised when the simulation is invoked before it was initialized.

`SimulationHaltedError`

Bases: SimulationError

The simulation has been intentionally stopped.

`SimulationTerminatedError`

Bases: SimulationError

The simulation has been terminated due to an earlier deadlock, message loss, missing recipient, model panic, timeout or synchronization loss

`SimulationDeadlockError`

Bases: SimulationError

Raised when the simulation has deadlocked.

`SimulationMessageLossError`

Bases: SimulationError

Raised when the recipient of a message does not exists.

`SimulationNoRecipientError`

Bases: SimulationError

Raised when the simulation is invoked before it was initialized.

`SimulationPanicError`

Bases: SimulationError

Raised when a panic is caught during execution.

`SimulationTimeoutError`

Bases: SimulationError

Raised when a simulation step fails to complete within the allocated time.

`SimulationOutOfSyncError`

Bases: SimulationError

Raised when the simulation has lost synchronization with the clock.

`SimulationBadQueryError`

Bases: SimulationError

Raised when a query did not obtain a response because the mailbox targeted by the query was not found in the simulation.

`SimulationTimeOutOfRangeError`

Bases: SimulationError

Raised when the provided simulation time is out of the range supported by the Python timestamp.

`SourceNotFoundError`

Bases: SimulationError

Raised when the provided name does not match any event or query source.

`SinkNotFoundError`

Bases: SimulationError

Raised when the provided name does not match any event sink.

`UnexpectedError`

Bases: SimulationError

Raised when an internal implementation error occurs.
