Class JRubyUtilLibrary

java.lang.Object

org.jruby.ext.jruby.JRubyUtilLibrary

All Implemented Interfaces:

Library

public class JRubyUtilLibrary
extends java.lang.Object
implements Library

Utilities library for all those methods that don't need the full 'java' library to be loaded. This is done mostly for performance reasons. For example, for those who only need to enable the object space, not loading 'java' might save 200-300ms of startup time, like in case of jirb.
