A configuration field (`~lsst.pex.config.Field` subclass) that takes a `~lsst.pex.config.Config`-type as a value. Parameters ---------- doc : `str` A description of the configuration field. dtype : `lsst.pex.config.Config`-type The type of the field, which must be a subclass of `lsst.pex.config.Config`. 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 : callable, optional A callback function that validates the field's value, returning `True` if the value is valid, and `False` otherwise. deprecated : None or `str`, 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. See Also -------- ChoiceField ConfigChoiceField ConfigDictField ConfigurableField DictField Field ListField RangeField RegistryField Notes ----- The behavior of this type of field is much like that of the base `Field` type. Assigning to ``ConfigField`` will update all of the fields in the configuration.

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.

Call the _collectImports method on all config objects the field may own, and union them with the supplied imports set. Parameters ---------- instance : instance or subclass of `lsst.pex.config.Config` A config object that has this field defined on it imports : `set` Set of python modules that need imported after persistence

Compare two fields for equality. Used by `ConfigField.compare`. Parameters ---------- instance1 : `lsst.pex.config.Config` Left-hand side config instance to compare. instance2 : `lsst.pex.config.Config` Right-hand side config instance to compare. shortcut : `bool` If `True`, this function returns as soon as an inequality if found. rtol : `float` Relative tolerance for floating point comparisons. atol : `float` Absolute tolerance for floating point comparisons. output : callable A callable that takes a string, used (possibly repeatedly) to report inequalities. Returns ------- isEqual : bool `True` if the fields are equal, `False` otherwise. Notes ----- Floating point comparisons are performed by `numpy.allclose`.

lsst.pex.config.configField.ConfigField.freeze | ( | self, | |
instance ) |
Make this field read-only. Parameters ---------- instance : `lsst.pex.config.Config` The config instance that contains this field. Notes ----- Freezing is only relevant for fields that hold subconfigs. Fields which hold subconfigs should freeze each subconfig. **Subclasses should implement this method.**

lsst.pex.config.configField.ConfigField.rename | ( | self, | |
instance ) |
Rename the field in a `~lsst.pex.config.Config` (for internal use only). Parameters ---------- instance : `lsst.pex.config.Config` The 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. Renaming is only relevant for `~lsst.pex.config.Field` instances that hold subconfigs. `~lsst.pex.config.Field`\s that hold subconfigs should rename each subconfig with the full field name as generated by `lsst.pex.config.config._joinNamePath`.

lsst.pex.config.configField.ConfigField.save | ( | self, | |
outfile, | |||
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.

lsst.pex.config.configField.ConfigField.toDict | ( | self, | |
instance ) |
Convert the field value so that it can be set as the value of an item in a `dict` (for internal use only). Parameters ---------- instance : `~lsst.pex.config.Config` The `~lsst.pex.config.Config` that contains this field. Returns ------- value : object The field's value. See *Notes*. Notes ----- This method invoked by the owning `~lsst.pex.config.Config` object and should not be called directly. Simple values are passed through. Complex data structures must be manipulated. For example, a `~lsst.pex.config.Field` holding a subconfig should, instead of the subconfig object, return a `dict` where the keys are the field names in the subconfig, and the values are the field values in the subconfig.

lsst.pex.config.configField.ConfigField.validate | ( | self, | |
instance ) |
Validate the field (for internal use only). Parameters ---------- instance : `lsst.pex.config.Config` The config instance that contains this field. Raises ------ lsst.pex.config.FieldValidationError Raised if verification fails. Notes ----- This method provides basic validation: - Ensures that the value is not `None` if the field is not optional. - Ensures type correctness. - Ensures that the user-provided ``check`` function is valid. Most `~lsst.pex.config.Field` subclasses should call `lsst.pex.config.Field.validate` if they re-implement `~lsst.pex.config.Field.validate`.
