Detailed Description

This interface allows extension providers to control how the instances provided to extension-points are being created by referring to the factory instead of referring to a class. For example, the following extension to the preference page extension-point uses a factory called PreferencePageFactory.

<extension point="org.blueberry.ui.preferencePages">
  <page  name="..."  class="org.eclipse.update.ui.PreferencePageFactory:org.eclipse.update.ui.preferences.MainPreferencePage">
  </page>
</extension>

Effectively, factories give full control over the create executable extension process.

The factories are responsible for handling the case where the concrete instance implements IExecutableExtension.

Given that factories are instantiated as executable extensions, they must provide a 0-argument public constructor. Like any other executable extension, they can be configured by implementing the IExecutableExtension interface.
