org.codehaus.groovy.runtime.ProxyGeneratorAdapter

A proxy generator responsible for mapping a map of closures to a class implementing a list of interfaces. For example, the following code:

 abstract class Foo { abstract void bar(); abstract void baz(); } def dyn = [bar: { println 'hello' }, baz: { println 'world'}] as Foo

will generate a proxy class which extends class Foo and delegates method calls to the provided closures. The generated proxy implements the {@link GroovyObject} interface.Additionaly, this proxy generator supports delegation to another object. In that case, if a method is defined both in the closure map and the delegate, the version from the map is preferred. This allows overriding methods from delegates with ease. Internally, the proxy generator makes use of ASM to generate bytecode, for improved performance as compared to the legacy proxy generation mechanism which made use of string templates. @author Cedric Champeau @since 2.0.0
