-
getAttribute
(attr_name, **kwargs)[source]¶ Obtain the object corresponding to the given attribute name. If the corresponding attribute already exists, the existing instance is returned. Otherwise a new instance is stored and returned. The evaluator device associated to this attribute will also be created if necessary.
Parameters: attr_name ( str
) – the attribute name string. Seetaurus.core.evaluation
for valid attribute namesAny aditional keyword arguments will be passed directly to the constructor of :class:EvaluationAttribute
Return type: EvaluationAttribute
Returns: @throws TaurusException if the given name is invalid.
-
getAuthority
(name=None)[source]¶ Obtain the EvaluationDatabase object.
Parameters: db_name ( str
) – this is ignored because only one database is supportedReturn type: EvaluationDatabase
Returns:
-
getDevice
(dev_name)[source]¶ Obtain the object corresponding to the given device name. If the corresponding device already exists, the existing instance is returned. Otherwise a new instance is stored and returned.
Parameters: dev_name ( str
) – the device name string. Seetaurus.core.evaluation
for valid device namesReturn type: EvaluationDevice
Returns: @throws TaurusException if the given name is invalid.
