Detailed Description

This locator uses special extended metadata (not available on PyPI) and is
the basis of performant dependency resolution in distlib. Other locators
require archive downloads before dependencies can be determined! As you
might imagine, that can be slow.

Member Function Documentation

_get_project()

pip._vendor.distlib.locators.JSONLocator._get_project (   self,   name  )

protected

For a given project, get a dictionary mapping available versions to Distribution
instances.

This should be implemented in subclasses.

If called from a locate() request, self.matcher will be set to a
matcher for the requirement to satisfy, otherwise it will be None.

Reimplemented from pip._vendor.distlib.locators.Locator.

get_distribution_names()

pip._vendor.distlib.locators.JSONLocator.get_distribution_names

(

self

)

Return all the distribution names known to this locator.

Reimplemented from pip._vendor.distlib.locators.Locator.
