API docs for “twisted.python.components”

Component architecture for Twisted, based on Zope3 components.

Using the Zope3 API directly is strongly recommended. Everything you need is in the top-level of the zope.interface package, e.g.:

  from zope.interface import Interface, implements

  class IFoo(Interface):
      pass

  class Foo:
      implements(IFoo)

  print IFoo.implementedBy(Foo) # True
  print IFoo.providedBy(Foo()) # True

The one exception is twisted.python.components.registerAdapter, which is still the way to register adapters (at least, if you want Twisted's global adapter registry).

def _registered 0(registry, required, provided): (source)

Return the adapter factory for the given parameters in the given registry, or None if there is not one.

def _registered(registry, required, provided): (source)

Return the adapter factory for the given parameters in the given registry, or None if there is not one.

def registerAdapter(adapterFactory, origInterface, *interfaceClasses): (source)

An adapter class is expected to implement the given interface, by adapting instances implementing 'origInterface'. An adapter class's __init__ method should accept one parameter, an instance implementing 'origInterface'.

def getAdapterFactory(fromInterface, toInterface, default): (source)

Return registered adapter for a given class and interface.

Note that is tied to the *Twisted* global registry, and will thus not find adapters registered elsewhere.

def backwardsCompatImplements(klass): (source)

DEPRECATED.

Does nothing. Previously handled backwards compat from a zope.interface using class to a class wanting old twisted components interface behaviors.

def fixClassImplements(klass): (source)

DEPRECATED.

Does nothing. Previously converted class from __implements__ to zope implementation.

def getRegistry(): (source)

Returns the Twisted global zope.interface.adapter.AdapterRegistry instance.
