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 Details

equals

public boolean equals(Object other)

Description copied from class: RubyObject

Overrides:

equals in class JavaProxyReflectionObject

• RubyBasicObject.equals(Object)

hashCode

public int hashCode()

Description copied from class: RubyObject

This override does not do "checked" dispatch since Object usually has #hash defined.

Overrides:

hashCode in class JavaProxyReflectionObject

See Also:

• RubyBasicObject.hashCode()

getValue

public Object getValue()

getSuperclass

public Class getSuperclass()

getInterfaces
