`ConfigurableActionField` is a subclass of `~lsst.pex.config.Field` that allows a single `ConfigurableAction` (or a subclass) to be assigned to it. The `ConfigurableAction` is then accessed through this field for further configuration. Any configuration of this field that is done prior to having a new `ConfigurableAction` assigned to it is forgotten. Parameters ---------- doc : `str` Documentation string. dtype : `ConfigurableAction` Data type to use for this field. default : `lsst.pex.config.Config`, optional If default is `None`, the field will default to a default-constructed instance of ``dtype``. Additionally, to allow for fewer deep-copies, assigning an instance of ``ConfigField`` to ``dtype`` itself is considered equivalent to assigning a default-constructed sub-config. This means that the argument default can be ``dtype``, as well as an instance of ``dtype``. check : `~collections.abc.Callable`, optional A callback function that validates the field's value, returning `True` if the value is valid, and `False` otherwise. deprecated : `bool` or `None`, optional A description of why this Field is deprecated, including removal date. If not `None`, the string is appended to the docstring for this Field.

Set an attribute on the config instance. Parameters ---------- instance : `lsst.pex.config.Config` The config instance that contains this field. value : obj Value to set on this field. at : `list` of `~lsst.pex.config.callStack.StackFrame` or `None`,\ optional The call stack (created by `lsst.pex.config.callStack.getCallStack`). label : `str`, optional Event label for the history. Notes ----- This method is invoked by the owning `lsst.pex.config.Config` object and should not be called directly. Derived `~lsst.pex.config.Field` classes may need to override the behavior. When overriding ``__set__``, `~lsst.pex.config.Field` authors should follow the following rules: - Do not allow modification of frozen configs. - Validate the new value **before** modifying the field. Except if the new value is `None`. `None` is special and no attempt should be made to validate it until `lsst.pex.config.Config.validate` is called. - Do not modify the `~lsst.pex.config.Config` instance to contain invalid values. - If the field is modified, update the history of the `lsst.pex.config.field.Field` to reflect the changes. In order to decrease the need to implement this method in derived `~lsst.pex.config.Field` types, value validation is performed in the `lsst.pex.config.Field._validateValue`. If only the validation step differs in the derived `~lsst.pex.config.Field`, it is simpler to implement `lsst.pex.config.Field._validateValue` than to reimplement ``__set__``. More complicated behavior, however, may require reimplementation.

lsst.pex.config.configurableActions._configurableActionField.ConfigurableActionField.save | ( | self, | |

instance ) |
Save this field to a file (for internal use only). Parameters ---------- outfile : file-like object A writeable field handle. instance : `~lsst.pex.config.Config` The `~lsst.pex.config.Config` instance that contains this field. Notes ----- This method is invoked by the `~lsst.pex.config.Config` object that contains this field and should not be called directly. The output consists of the documentation string (`lsst.pex.config.Field.doc`) formatted as a Python comment. The second line is formatted as an assignment: ``{fullname}={value}``. This output can be executed with Python.
