Class JavaProxyClass

java.lang.Object

org.jruby.RubyBasicObject

org.jruby.RubyObject

org.jruby.javasupport.proxy.JavaProxyReflectionObject

org.jruby.javasupport.proxy.JavaProxyClass

All Implemented Interfaces:

Serializable, Cloneable, Comparable<IRubyObject>, InstanceVariables, InternalVariables, IRubyObject, CoreObjectType

public class JavaProxyClass
extends JavaProxyReflectionObject

Generalized proxy for classes and interfaces. API looks a lot like java.lang.reflect.Proxy, except that you can specify a super class in addition to a set of interfaces. The main implication for users of this class is to handle the case where a proxy method overrides an existing method, because in this case the invocation handler should "default" to calling the super implementation {JavaProxyMethod.invokeSuper}.

Method Detail

equals

public boolean equals(Object other)

Description copied from class: RubyObject

This method is just a wrapper around the Ruby "==" method, provided so that RubyObjects can be used as keys in the Java HashMap object underlying RubyHash.

Overrides:

equals in class JavaProxyReflectionObject

hashCode

public int hashCode()

Description copied from class: RubyObject

Override the Object#hashCode method to make sure that the Ruby hash is actually used as the hashcode for Ruby objects. If the Ruby "hash" method doesn't return a number, the Object#hashCode implementation will be used instead.

Overrides:

hashCode in class JavaProxyReflectionObject
