iPOJO API

iPOJO API

The iPOJO API provides a third way to describe iPOJO components and instances. With the API, you can dynamically create new components types and create instances from them. Your component types are described with a Java API. To use the API, deploy and start the iPOJO-API bundle and the iPOJO core bundle.

Describing your iPOJO components

This section describes the different features supported by iPOJO. This page aims to answer to the following question: "What can I write in my iPOJO component descriptor?"

A missing functionality ?

iPOJO component model is extensible. So, you can implement your own handler managing you specific requirement. Refer the handler development guide (How to write your own handler) for more details.

Introspection and Architecture

Introspection and Architecture

The architecture feature allows obtaining an architectural / component view of your systems. It exposes a snapshot of the present instances & factories, the state of these instances... Moreover; iPOJO defines an 'arch' command displaying this architecture in Felix. You need to install the arch command.

{div:class=toc} [TOC] @@ -237,31 +178,37 @@

More info on the arch command are available here.

Technical information

In fact, when a component enables the architecture introspection, its container exposes an Architecture service. Any architecture requester can obtain information about the instance. For example, the arch command requests all the architecture services and prints the information.
