Class JRubyClassLoader

java.lang.ClassLoader

java.security.SecureClassLoader

java.net.URLClassLoader

org.jruby.util.ClassDefiningJRubyClassLoader

org.jruby.util.JRubyClassLoader

All Implemented Interfaces:

Closeable, AutoCloseable, ClassDefiningClassLoader

Direct Known Subclasses:

SelfFirstJRubyClassLoader

public class JRubyClassLoader
extends ClassDefiningJRubyClassLoader

this classloader will be populated dynamically in the following ways:

JRuby.runtime.jruby_class_loader.add_url( java.net.URL.new( "file:my.jar" )

$CLASSPATH << 'path/to/class/or/resources'

require 'some.jar'

load 'some.jar'

so it is the classloader for ALL the jars used by gems. and this classlaoder is "implicit" part of the $LOAD_PATH of the jruby runtime all ruby resources inside any of the added jars will be found via require and load
