This extension point is used to register plugins that want to be activated on startup. The class given as the attribute on the startup element must implement the interface org.eclipse.ui.IStartup
. Once the workbench is started, the method earlyStartup() will be called from a separate thread.
If the startup element has a class attribute, the class will be instantiated and earlyStartup() will be called on the result. Otherwise, this method will be called on the plug-in class. Do not specify the plug-in class as the value of the class attribute, or it will be instantiated twice (once by regular plug-in activation, and once by this mechanism).
If the extension does not provide a class as an attribute on the startup element, the plug-in's activator (plug-in class) must implement org.eclipse.ui.IStartup
. Note that this form is deprecated and should no longer be used. Its functioning relies on the availability of the org.eclipse.core.runtime.compatibility plug-in and the org.eclipse.core.runtime.compatibility.registry fragment.
Plugins that provide an extension to this extension point are listed in the workbench preferences and the user may disable any plugin from early startup.
