Other initialization steps such as requesting devices may also be
|
||||
performed here.
|
||||
|
||||
When the repository is scanned, any requested devices and arguments
|
||||
are set to ``None``.
|
||||
There are two situations where the requested devices are replaced by
|
||||
``DummyDevice()`` and arguments are set to their defaults (or ``None``)
|
||||
instead: when the repository is scanned to build the list of
|
||||
available experiments and when the dataset browser ``artiq_browser``
|
||||
is used to open or run the analysis stage of an experiment. Do not
|
||||
rely on being able to operate on devices or arguments in ``build()``.
|
||||
|
||||
Datasets are read-only in this method.
