Class NativeDelegateLibrary

org.jruby.ext.delegate.NativeDelegateLibrary

All Implemented Interfaces:

Library

public class NativeDelegateLibrary
extends java.lang.Object
implements Library

This library extends the delegate stdlib with a native method_missing, in order to reduce the cost of delegating through to the target object. It only supports 1.9 and higher, since 1.8 actively defined all methods from the target object rather than simply delegating all calls through method_missing. Note that this does no call site caching and interferes with advanced call site binding logic as found in our invokedynamic support. Future improvement would be to cache recent methods or wire up indy logic to see through delegation.
