Plugin Manager
The PluginManager is a very simple component container. It creates and organizes components (plugins), and helps select a plugin in the cases where there are many possible choices. It also gives some limited control over the lifecycle of a plugin.
A plugin is defined by a Java interface. The consumer of a plugin asks for its plugin by interface. A Plugin is an instance of any class that implements the plugin interface. It is interchangeable with other implementations, so that any of them may be "plugged in".
The mediafilter is a simple example of a plugin implementation. Refer to the Business Logic Layer for more details on Plugins.
