Detailed Description

A cache of wheels for future installs.

Constructor & Destructor Documentation

__init__()

None pip._internal.cache.SimpleWheelCache.__init__	(		self,
		str	cache_dir
	)

Reimplemented from pip._internal.cache.Cache.

Member Function Documentation

get()

Link pip._internal.cache.SimpleWheelCache.get	(		self,
		Link	link,
		Optional[str]	package_name,
		List[Tag]	supported_tags
	)

Returns a link to a cached item if it exists, otherwise returns the
passed link.

Reimplemented from pip._internal.cache.Cache.

get_path_for_link()

str pip._internal.cache.SimpleWheelCache.get_path_for_link	(		self,
		Link	link
	)

Return a directory to store cached wheels for link

Because there are M wheels for any one sdist, we provide a directory
to cache them in, and then consult that directory when looking up
cache hits.

We only insert things into the cache if they have plausible version
numbers, so that we don't contaminate the cache with things that were
not unique. E.g. ./package might have dozens of installs done for it
and build a version of 0.0...and if we built and cached a wheel, we'd
end up using the same wheel even if the source has been edited.

:param link: The link of the sdist for which this will cache wheels.

Reimplemented from pip._internal.cache.Cache.
