Package org.apache.isis.core.commons.components Description

Defines a Component architecture, along with factories (called Installers) to install (or create) those components.

There are three subinterfaces of Component, for three different scopes:

• application-scoped

• session-scoped

• transaction-scoped

Many Components may also be Injectable, meaning that they know hot to inject themselves to a candidate object "if appropriate". The convention adopted in most cases is for an object requiring injection of component Xxx to implement an XxxAware interface that defines a setXxx(Xxx) method.
