A configuration field (`~lsst.pex.config.Field` subclass) that contains a list of values of a specific type. Parameters ---------- doc : `str` A description of the field. dtype : class The data type of items in the list. default : sequence, optional The default items for the field. optional : `bool`, optional Set whether the field is *optional*. When `False`, `lsst.pex.config.Config.validate` will fail if the field's value is `None`. listCheck : callable, optional A callable that validates the list as a whole. itemCheck : callable, optional A callable that validates individual items in the list. length : `int`, optional If set, this field must contain exactly ``length`` number of items. minLength : `int`, optional If set, this field must contain *at least* ``minLength`` number of items. maxLength : `int`, optional If set, this field must contain *no more than* ``maxLength`` number of items. 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.

Delete an attribute from a `lsst.pex.config.Config` instance. Parameters ---------- instance : `lsst.pex.config.Config` The config instance that contains this field. at : `list` of `lsst.pex.config.callStack.StackFrame` The call stack (created by `lsst.pex.config.callStack.getCallStack`). label : `str`, optional Event label for the history. Notes ----- This is invoked by the owning `~lsst.pex.config.Config` object and should not be called directly.

Define how attribute access should occur on the Config instance This is invoked by the owning config object and should not be called directly When the field attribute is accessed on a Config class object, it returns the field object itself in order to allow inspection of Config classes. When the field attribute is access on a config instance, the actual value described by the field (and held by the Config instance) is returned.

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` 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.

Make this field read-only (for internal use 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.**

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.Fields` that hold subconfigs should rename each subconfig with the full field name as generated by `lsst.pex.config.config._joinNamePath`.

Save this field to a file (for internal use only). Parameters ---------- outfile : file-like object A writeable field handle. instance : `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. 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.

def pex.config.listField.ListField.toDict | ( | self, | |
instance | |||
) |
Convert the value of this field to a plain `list`. `lsst.pex.config.Config.toDict` is the primary user of this method. Parameters ---------- instance : `lsst.pex.config.Config` The config instance that contains this field. Returns ------- `list` Plain `list` of items, or `None` if the field is not set.

def pex.config.listField.ListField.validate | ( | self, | |
instance | |||
) |
Validate the field. Parameters ---------- instance : `lsst.pex.config.Config` The config instance that contains this field. Raises ------ lsst.pex.config.FieldValidationError Raised if: - The field is not optional, but the value is `None`. - The list itself does not meet the requirements of the `length`, `minLength`, or `maxLength` attributes. - The `listCheck` callable returns `False`. Notes ----- Individual item checks (`itemCheck`) are applied when each item is set and are not re-checked by this method.
