Package org.apache.nutch.plugin Description

The Nutch Plugin System.

The Nutch Plugin System provides a way to extend nutch functionality. A large part of the functionality of Nutch are provided by plugins: All of the parsing, indexing and searching that nutch does is actually accomplished by various plugins.

In writing a plugin, you're actually providing one or more extensions of the existing extension-points (hooks). The core Nutch extension-points are themselves defined in a plugin, the nutch-extensionpoints plugin. Each extension-point defines an interface that must be implemented by the extension. The core extension-points and extensions available in Nutch are listed in the Pluggable interface.
