======================
Component Registries
======================
The component registry's API is defined by
``zope.interface.interfaces.IComponents``:
.. autointerface:: zope.interface.interfaces.IComponentLookup
:members:
:member-order: bysource
.. autointerface:: zope.interface.interfaces.IComponentRegistry
:members:
:member-order: bysource
.. autointerface:: zope.interface.interfaces.IComponents
:members:
:member-order: bysource
One default implementation of `~zope.interface.interfaces.IComponents` is provided.
.. autoclass:: zope.interface.registry.Components
Events
======
Adding and removing components from the component registry create
registration and unregistration events. Like most things, they are
defined by an interface and a default implementation is provided.
Registration
------------
.. autointerface:: zope.interface.interfaces.IObjectEvent
.. autointerface:: zope.interface.interfaces.IRegistrationEvent
.. autointerface:: zope.interface.interfaces.IRegistered
.. autoclass:: zope.interface.interfaces.Registered
.. autointerface:: zope.interface.interfaces.IUnregistered
.. autoclass:: zope.interface.interfaces.Unregistered
Details
-------
These are all types of ``IObjectEvent``, meaning they have an object
that provides specific details about the event. Component registries
create detail objects for four types of components they manage.
All four share a common base interface.
.. autointerface:: zope.interface.interfaces.IRegistration
* Utilities
.. autointerface:: zope.interface.interfaces.IUtilityRegistration
.. autoclass:: zope.interface.registry.UtilityRegistration
* Handlers
.. autointerface:: zope.interface.interfaces.IHandlerRegistration
.. autoclass:: zope.interface.registry.HandlerRegistration
* Adapters
For ease of implementation, a shared base class is used for these
events. It should not be referenced by clients, but it is documented
to show the common attributes.
.. autointerface:: zope.interface.interfaces._IBaseAdapterRegistration
.. autointerface:: zope.interface.interfaces.IAdapterRegistration
.. autoclass:: zope.interface.registry.AdapterRegistration
.. autointerface:: zope.interface.interfaces.ISubscriptionAdapterRegistration
.. autoclass:: zope.interface.registry.SubscriptionRegistration
Exceptions
==========
.. autoclass:: zope.interface.interfaces.ComponentLookupError
.. autoclass:: zope.interface.interfaces.Invalid
