package metaobjectTest
@doc{*
Annotation 'renameMethod' should be attached to a prototype.
It takes at least two parameters: the first is a method name
and the others are the new selectors for the method. Example:
@renameMethod("at:1 with:2", "myAt:", "myWith:")
This annotation will rename method "at:1 with: 2" to "myAt:1 myWith:2".
Overloaded methods cannot be renamed.
Annotation 'renameMethod' should be attached to a prototype.
It takes at least four parameters.
The first one is the signature of the method to be renamed. This signature is
got from method getNameWithoutParamNumber of WrMethodSignature or WrMethodDec.
Something like
"""
func one: Int n
two: Int nn, Double d
three: String a, String b, String c -> Int"""
The Cyan MOP demands that, if a method is renamed, other should be
created with this same name. The code of the NEW method, with the OLD
method name, is in the second parameter. Something like
"""
func one: Int n
two: Int nn, Double d
three: String a, String b, String c -> Int {
var value = n + nn + d asInt;
Out println: a, b, c;
return value;
}
"""
The third parameter is the OLD method name composed of method keywords
and number of parameters, something like
"one:1 two:2 three:3"
The rest of the parameters are the new keywords for the method, for
example,
"um:", "dois:", "tres:"
Overloaded methods cannot be renamed.
