[jira] Closed: (GROOVY-4905) polymorphic static methods

[Jose Antonio Illescas del Olmo]

After response of Jochen Theodorou I decided discuss this feature on mailing
list...

I proposed, as real Object Oriented languages (smalltalk,...) does, that
"this" on static method references the Class that receive the message
(method) instead of the Class that declare the method.

Example:

class A {
public static foo() {
println("foo: " + this);
}
}

class B extends A {}

class C extends B {}

Calling "foo" method with subclasses:

A.foo(); // class A is the "foo" message receptor
B.foo(); // class B is the "foo" message receptor
C.foo(); // class C is the "foo" message receptor

Now returns:

foo: class A
foo: class A
foo: class A

I Propose that result must be:

foo: class A
foo: class B
foo: class C




Thank you

Resolution: Won't Fix

"this" has already a meaning different then what you suggest in a static
context. So this change would be a breaking change. I suggest the mailing
list for further discussion, if needed

polymorphic static methods
--------------------------
Key: GROOVY-4905
URL: https://jira.codehaus.org/browse/GROOVY-4905
Project: groovy
Issue Type: New Feature
Reporter: joseaio
Assignee: Jochen Theodorou
Nex Class Hierarchy: A < B < C
class A {
public static foo() {
println("foo: "+ this);
}
}
class B extends A {}
class C extends B {}
A.foo(); // class A is the "foo" message receptor
B.foo(); // class B is the "foo" message receptor
C.foo(); // class C is the "foo" message receptor
foo: class A
foo: class A
foo: class A
On Object Oriented "this" references message receptor (on static method is

the Class)...

foo: class A
foo: class B
foo: class C
