tango.pyaml.attribute_list_read_only

Read-only list of Tango attributes handled through Tango groups.

Classes

AttributeListReadOnly(attributes[, name, unit])	Handle a read-only list of Tango attributes using Tango Groups.
AttributeListReadOnlyConfig(*, attributes[, ...])	Configuration model for a read-only list of Tango attributes.

class tango.pyaml.attribute_list_read_only.AttributeListReadOnly(attributes, name='', unit='')

Bases: AttributeList, DynamicValidation

Handle a read-only list of Tango attributes using Tango Groups.

Same as AttributeList, except that asynchronous writes through set() are rejected.

Parameters:

• attributes (list of str) – List of Tango attribute paths.

• name (str, optional) – Group name.

• unit (str, optional) – Unit of the attributes.

_attributes

Tango attribute paths in configured order.

Type:

list of str

_name

Group name.

Type:

str

_unit

Unit of the attributes.

Type:

str

set(value)

Disallowed asynchronous write operation.

set_and_wait(value)

Write a value synchronously to all Tango attributes.

set(value)

Disallowed asynchronous write operation.

Parameters:

value (float) – Ignored.

Raises:

pyaml.PyAMLException – Always raised because the attribute list is read-only.

set_and_wait(value)

Write a value synchronously to all Tango attributes.

Parameters:

value (float) – Value to write.

class tango.pyaml.attribute_list_read_only.AttributeListReadOnlyConfig(*, attributes, name='', unit='')

Bases: AttributeListConfig

Configuration model for a read-only list of Tango attributes.

Create a new model by parsing and validating input data from keyword arguments.

Raises [ValidationError][pydantic_core.ValidationError] if the input data cannot be validated to form a valid model.

self is explicitly positional-only to allow self as a field name.

model_config: ClassVar[ConfigDict] = {}

Configuration for the model, should be a dictionary conforming to [ConfigDict][pydantic.config.ConfigDict].
