Hardware Constraints

Module to handle hardware constraints

class qarnot.hardware_constraint.HardwareConstraint

Bases: object

Represents a hardware constraint.

classmethod from_json(json: Dict[str, Any])

Create an hardware constraint from json.

Parameters

• connection (qarnot.connection.Connection) – the cluster connection

• json (dict) – Dictionary representing the constraint

Returns

The created HardwareConstraint.

abstract to_json()

Get a dict ready to be json packed.

Raises

NotImplementedError – this is an abstract method, it should be overridden in child classes
