This represents the information available in a Java .class file. This interface is used by {@link ClosureCompilerImpl} for closure computation. Theinterface only represents the information as needed by api scanning feature in verifier. I expect it to evolve over time to something very similar to BCEL's ClassFile. Now a note about different ways a Java class can be named and in different places different names are used for the same Java class. 1) In the format "p.a.b". This is what we use when declaring variables etc in a Java code. I do not use this because this is not an unambiguous representation of a Java class. By looking at p.a.b it is not possible to say if b is an inner class in class p.a or b is an outer class in package p.a. 2) In the format "p.outer$inner". It is what is used when we invoke java command or Class.forName(). It is same as what is returned by java.lang.Class.getName() method. It is an unambiguous representation of a class name, because by looking at it, we can tell "inner" is an inner class of a class "outer" which belongs to package p. By default our {@link #getName()} returns in this format. 3) In the format "p/outer$inner" This isthe internal name of a class. It is called internal name because in byte code this is what is encoded. It is again an unambiguous representation as this a path expression. It is fairly simple to convert from 2 to 3 by a simple call to String.replace('.','/'). Similarly to convert from 3 to 2, call String.replace('/','.'); Here is a test of what you understood. What does this class name "a$b.c$d.Foo$Bar$Goo" mean? "Goo" is an inner class in a class "Foo$Bar" which is defined in a package "a$b.c$d". @author Sanjeeb.Sahoo@Sun.COM
