some attributes are handled at allocation time rather than at
initialization.

This ensures that even if a derived `~lsst.pex.config.Config` class
implements ``__init__``, its author does not need to be concerned about
when or even the base ``Config.__init__`` should be called.

Notes
-----
Unlike normal Python objects, `~lsst.pex.config.Config` objects are
locked such that no additional attributes nor properties may be added
to them dynamically.

users from accidentally mispelling a field name, or trying to set a

update()

def lsst.pex.config.config.Config.update (   self,   kw  )

inherited

Update values of fields specified by the keyword arguments.

Parameters
----------
kw
    Keywords are configuration field names. Values are configuration
    field values.

Notes
-----
The ``__at`` and ``__label`` keyword arguments are special internal
keywords. They are used to strip out any internal steps from the
history tracebacks of the config. Do not modify these keywords to
subvert a `~lsst.pex.config.Config` instance's history.

Examples
--------
This is a config with three fields:

>>> from lsst.pex.config import Config, Field
>>> class DemoConfig(Config):
...     fieldA = Field(doc='Field A', dtype=int, default=42)
...     fieldB = Field(doc='Field B', dtype=bool, default=True)
...     fieldC = Field(doc='Field C', dtype=str, default='Hello world')
...
>>> config = DemoConfig()

These are the default values of each field:

>>> for name, value in config.iteritems():
...     print(f"{name}: {value}")
...
fieldA: 42
fieldB: True
fieldC: 'Hello world'

Using this method to update ``fieldA`` and ``fieldC``:

>>> config.update(fieldA=13, fieldC='Updated!')

Now the values of each field are:

>>> for name, value in config.iteritems():
...     print(f"{name}: {value}")
...
fieldA: 13
fieldB: True
fieldC: 'Updated!'

Validate the Config, raising an exception if invalid.

Raises
------
lsst.pex.config.FieldValidationError
    Raised if verification fails.

Notes
-----
The base class implementation performs type checks on all fields by
calling their `~lsst.pex.config.Field.validate` methods.

Complex single-field validation can be defined by deriving new Field
types. For convenience, some derived `lsst.pex.config.Field`-types
(`~lsst.pex.config.ConfigField` and
`~lsst.pex.config.ConfigChoiceField`) are defined in `lsst.pex.config`
that handle recursing into subconfigs.

Inter-field relationships should only be checked in derived
`~lsst.pex.config.Config` classes after calling this method, and base
validation is complete.
