Class InterfaceExtractor

java.lang.Object

org.springsource.loaded.InterfaceExtractor

public class InterfaceExtractor
extends java.lang.Object

Extract an interface for a type. The interface embodies the shape of the type as originally loaded. The key difference with methods in the interface is that they contain an extra (leading) parameter that is the type of the original loaded class.
For example:

 class Foo {
   public String foo(int i) {}
 }
 

will cause creation of an interface method:

 
 String foo(Foo instance, int i) {}
 

Since:

0.5.0
