Interface ScriptLanguage

All Superinterfaces:

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

All Known Implementing Classes:

AbstractScriptLanguage, AdaptedScriptLanguage

public interface ScriptLanguage
extends ScriptEngineFactory, RichPlugin, SingletonPlugin

The base interface for scripting language adapters.

Every ImageJ scripting language implements this interface, which is based on JSR 223, Scripting for the Java Platform, included in Java 6 and later in the javax.script package. This ScriptLanguage interface extends ScriptEngineFactory, meaning it can act as a JSR 223 Java scripting language, while also providing additional functionality necessary for full support within ImageJ. In particular, this interface adds API for code generation of scripts to replicate ImageJ Module executions (i.e., for "script recording" of ImageJ commands).

Script languages discoverable at runtime must implement this interface and be annotated with @Plugin with attribute Plugin.type() = ScriptLanguage.class. While it possible to create a scripting language adapter merely by implementing this interface, it is encouraged to instead extend AbstractScriptLanguage, for convenience.
