public Interface Composable

Known Direct Subinterfaces
org.apache.avalon.framework.component.Recomposable
A Composable class is one that needs to connect to software components using a "role" abstraction, thus not depending on particular implementations but on behavioral interfaces.

The contract surrounding a Composable is that it is a user. The Composable is able to use Components managed by the ComponentManager it was initialized with. As part of the contract with the system, the instantiating entity must call the compose method before the Composable can be considered valid.

Deprecated: Use org.apache.avalon.framework.service.Serviceable instead.
