Given a method invocation, can I get the names of the parameters of the
invoked method?

I would like to get such names even from methods only found in
classfiles/bytecode and not necessarily available in source. Granted such
methods would have the debugging information.

Thanks in advance.

Do you mean the names of the arguments passed to the method invocation? If
so something like the following should work:

private String getMethodArguments(MethodInvocation method) {
StringBuilder args = new StringBuilder();
for (int i = 0; i < method.arguments().size(); i++) {
args.append(((Expression) method.arguments().get(i)).toString());
if (i < method.arguments().size() - 1) {
args.append(", ");
}
}
return args.toString();
}

Hi,

I mean the names of the parameters of the invoked method.

Given a method invocation: GUI.createWindow(1, 2), I would like to see
that 1 is passed to parameter named 'length' and 2 to 'width'. This is
provided that the declaration is: Window createWindow(int length, int
width); but we may only have the bytecode for such declaration (but with
debugging information).

Seems overly complicated. Just get the javadocs.
