class EvaluationFactory(*p, **k)[source]

A Singleton class that provides Evaluation related objects.

Import from taurus.core.evaluation as:

from taurus.core.evaluation import EvaluationFactory
DEFAULT_AUTHORITY = '//localhost'
DEFAULT_DATABASE = '_DefaultEvalDB'
DEFAULT_DEVICE = '@DefaultEvaluator'
elementTypesMap = {3: <class 'taurus.core.evaluation.evaldevice.EvaluationDevice'>, 13: <class 'taurus.core.evaluation.evalattribute.EvaluationAttribute'>, 18: <class 'taurus.core.evaluation.evalauthority.EvaluationAuthority'>}
findObjectClass(absolute_name)[source]

Operation models are always OperationAttributes

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. See taurus.core.evaluation for valid attribute names

Returns:

Return type:

EvaluationAttribute

Raises:

TaurusException if the given name is invalid.

Any aditional keyword arguments will be passed directly to the constructor of :class:EvaluationAttribute

getAttributeNameValidator()[source]

Return EvaluationAttributeNameValidator

getAuthority(name=None)[source]

Obtain the EvaluationDatabase object.

Parameters:

db_name (str) – this is ignored because only one database is supported

Returns:

Return type:

EvaluationDatabase

getAuthorityNameValidator()[source]

Return EvaluationAuthorityNameValidator

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. See taurus.core.evaluation for valid device names

Returns:

Return type:

EvaluationDevice

@throws TaurusException if the given name is invalid.

getDeviceNameValidator()[source]

Return EvaluationDeviceNameValidator

init(*args, **kwargs)[source]

Singleton instance initialization.
