[3.14] gh-143513: Remove importlib.abc documentation for removed ABCs (GH-143605) (GH-144166)
gh-143513: Remove importlib.abc documentation for removed ABCs (GH-143605) In 3.11 ResourceReader, Traversable, & TraversableResources moved from importlib.abc to importlib.resources.abc (commit e712a5b277866a71c195f38c1b5d87d9126dba3e). In 3.12 old import locations were deprecated (commit 71848c960927af801656026203371c41ad139b5a). In 3.14 backwards-compat support was removed (commit 0751511d24295c39fdf2f5b2255e3fa3d796ce4d). (cherry picked from commit f8262b84f5b76e45cfea9d73b09657919926850f) Co-authored-by: Alex Willmer <alex@moreati.org.uk> Co-authored-by: Brett Cannon <brett@python.org>

.. class:: ResourceReader
|
||||
|
||||
*Superseded by TraversableResources*
|
||||
|
||||
An :term:`abstract base class` to provide the ability to read
|
||||
*resources*.
|
||||
|
||||
From the perspective of this ABC, a *resource* is a binary
|
||||
artifact that is shipped within a package. Typically this is
|
||||
something like a data file that lives next to the ``__init__.py``
|
||||
file of the package. The purpose of this class is to help abstract
|
||||
out the accessing of such data files so that it does not matter if
|
||||
the package and its data file(s) are stored e.g. in a zip file
|
||||
versus on the file system.
|
||||
|
||||
For any of methods of this class, a *resource* argument is
|
||||
expected to be a :term:`path-like object` which represents
|
||||
conceptually just a file name. This means that no subdirectory
|
||||
paths should be included in the *resource* argument. This is
|
||||
because the location of the package the reader is for, acts as the
|
||||
"directory". Hence the metaphor for directories and file
|
||||
names is packages and resources, respectively. This is also why
|
||||
instances of this class are expected to directly correlate to
|
||||
a specific package (instead of potentially representing multiple
|
||||
packages or a module).
|
||||
|
||||
Loaders that wish to support resource reading are expected to
|
||||
provide a method called ``get_resource_reader(fullname)`` which
|
||||
returns an object implementing this ABC's interface. If the module
|
||||
specified by fullname is not a package, this method should return
|
||||
:const:`None`. An object compatible with this ABC should only be
|
||||
returned when the specified module is a package.

.. deprecated-removed:: 3.12 3.14
|
||||
Use :class:`importlib.resources.abc.TraversableResources` instead.
|
||||
|
||||
.. method:: open_resource(resource)
|
||||
:abstractmethod:
|
||||
|
||||
Returns an opened, :term:`file-like object` for binary reading
|
||||
of the *resource*.
|
||||
|
||||
If the resource cannot be found, :exc:`FileNotFoundError` is
|
||||
raised.
|
||||
|
||||
.. method:: resource_path(resource)
|
||||
:abstractmethod:
|
||||
|
||||
Returns the file system path to the *resource*.
|
||||
|
||||
If the resource does not concretely exist on the file system,
|
||||
raise :exc:`FileNotFoundError`.
|
||||
|
||||
.. method:: is_resource(name)
|
||||
:abstractmethod:
|
||||
|
||||
Returns ``True`` if the named *name* is considered a resource.
|
||||
:exc:`FileNotFoundError` is raised if *name* does not exist.
|
||||
|
||||
.. method:: contents()
|
||||
:abstractmethod:
|
||||
|
||||
Returns an :term:`iterable` of strings over the contents of
|
||||
the package. Do note that it is not required that all names
|
||||
returned by the iterator be actual resources, e.g. it is
|
||||
acceptable to return names for which :meth:`is_resource` would
|
||||
be false.
|
||||
|
||||
Allowing non-resource names to be returned is to allow for
|
||||
situations where how a package and its resources are stored
|
||||
are known a priori and the non-resource names would be useful.
|
||||
For instance, returning subdirectory names is allowed so that
|
||||
when it is known that the package and resources are stored on
|
||||
the file system then those subdirectory names can be used
|
||||
directly.
|
||||
|
||||
The abstract method returns an iterable of no items.
|
||||
|
||||
|
||||
.. class:: Traversable
|
||||
|
||||
An object with a subset of :class:`pathlib.Path` methods suitable for
|
||||
traversing directories and opening files.
|
||||
|
||||
For a representation of the object on the file-system, use
|
||||
:meth:`importlib.resources.as_file`.

*mode* may be 'r' or 'rb' to open as text or binary. Return a handle
|

accepted by :class:`io.TextIOWrapper`.

:class:`importlib.resources.abc.ResourceReader` and provides

concrete implementations of the :class:`importlib.resources.abc.ResourceReader`'s

abstract methods. Therefore, any loader supplying

:class:`importlib.abc.TraversableResources` also supplies ResourceReader.
