Interface DeploymentPackage</H2>

<DT><PRE>public interface <B>DeploymentPackage</B></DL>
</PRE>
<P>
The <code>DeploymentPackage</code> object represents a deployment package
(already installed or being currently processed). A Deployment Package groups
resources as a unit of management. A deployment package is something that can
be installed, updated, and uninstalled as a unit. A deployment package is a
reified concept, like a bundle, in an OSGi Service Platform. It is not known
by the OSGi Framework, but it is managed by the Deployment Admin service. A
deployment package is a stream of resources (including bundles) which, once
processed, will result in new artifacts (effects on the system) being added
to the OSGi platform. These new artifacts can include installed Bundles, new
configuration objects added to the Configuration Admin service, new Wire
objects added to the Wire Admin service, or changed system properties, etc.
All the changes caused by the processing of a deployment package are
persistently associated with the deployment package, so that they can be
appropriately cleaned up when the deployment package is uninstalled. There is
a strict no overlap rule imposed on deployment packages. Two deployment
packages are not allowed to create or manipulate the same artifact.
Obviously, this means that a bundle cannot be in two different deployment
packages. Any violation of this no overlap rule is considered an error and
the install or update of the offending deployment package must be aborted.
<p>
The Deployment Admin service should do as much as possible to ensure
transactionality. It means that if a deployment package installation, update
or removal (uninstall) fails all the side effects caused by the process
should be disappeared and the system should be in the state in which it was
before the process.
<p>
If a deployment package is being updated the old version is visible through
the <code>DeploymentPackage</code> interface until the update process ends.
After the package is updated the updated version is visible and the old one
is not accessible any more.
