org.scijava.app
Interface App

All Superinterfaces:

Comparable<Prioritized>, Contextual, HasPluginInfo, Prioritized, RichPlugin, SciJavaPlugin, SingletonPlugin, Versioned

All Known Implementing Classes:

AbstractApp, SciJavaApp

public interface App
extends RichPlugin, SingletonPlugin, Versioned

Metadata about a SciJava-based application, used by the AppService.

Applications discoverable at runtime must implement this interface and be annotated with @Plugin with attribute Plugin.type() = App.class. While it possible to create an application merely by implementing this interface, it is encouraged to instead extend AbstractApp, for convenience.
