Package org.jruby.anno

Class IndyBinder

java.lang.Object

javax.annotation.processing.AbstractProcessor

org.jruby.anno.IndyBinder

All Implemented Interfaces:

Processor

@SupportedAnnotationTypes("org.jruby.anno.JRubyMethod")
public class IndyBinder
extends AbstractProcessor

Annotation processor for generating "populators" to bind native Java methods as Ruby methods, and to gather a list of classes seen during compilation that should have their invokers regenerated. NOTE: This class must ONLY reference classes in the org.jruby.anno package, to avoid forcing a transitive dependency on any runtime JRuby classes.
