devel/py-zope.component 4.2.2_1 DragonFly

zope.component, together with zope.interface, provides facilities for defining, registering and looking up components.

There are two basic kinds of components: adapters and utilities.

Utilities are just components that provide an interface and that are looked up by an interface and a name.

Adapters are components that are computed from other components to adapt them to some interface. Because they are computed from other objects, they are provided as factories, usually classes.
