Revision 17451, 1.3 kB (checked in by foom, 3 years ago)

Remove twisted.components.Interface completely.

Merges: killtpc-1636-2
Authors: glyph, therve, jknight
Reviewer: exarkun

Remove deprecated twisted.python.components functionality:
MetaInterface?, Interface, getAdapterClass, and
getAdapterClassWithInheritance.

Also convert all twisted interfaces to use zope.interface directly
(including removing "self" argument), and remove redundant tests.
