Function list with Java problems
-
I’ve found several problems using function list for Java.
-
closing bracket “}” must not be the last character
there must be at least one chcracter beyond. Can be space or newline.public class MyClass {
void method() {
}
} -
comments don’t work at all
If there is comment inside my class the function list produces no output at all.public class MyClass {
// this comment must not be here
/* this also breaks the functionlist */
void method() {
// even this comment is wrong
}
} -
nested classes not recognized
No support for nested classes. I would really appreciate if ClassRange would be recursivepublic class OuterClass {
private class InnerClass { // this class is not in functionlist
void innerMethod() { // this method is placed in OuterClass
}
}
void outerMethod() {
}
} -
template classes extending other templates
I created my custom Collection. The implemented interface destroyed the function list.public class MyCollection<T> implements Collection<T> {
void overrideCollectionMethods() {
}
} -
templates limiting the template type
My collection was used for certain types only. This was also not recognized.public class MyCollection<T extends MyInterface> {
void someMethod() {
}
}

- Known issue, is being worked on;
- Known issue, is being worked on;
- Correct, nested classes are not supported; It’s implementation raises a whole new set of questions/challenges; Won’t implement in near future;
- I’ll look into this;
- I’ll look into this (as related to no.4).

-
interface (abstract classes) methods are not recognized
regex for method recognition requires method implementation {…}. Abstract methods are not recognized.public interface MyInterface {
public void method();
}

I did some investigation on templates and I ended up with this FunctionList. Please check it out.

A= Argument?
D= Declarator?

@Petr-Skýpala Based on your post I adapted the parser to:

Thanx! -
Hi MAPJe71,
Ah, Indeed ! I’ve never thought yet, about using the
(?x)modifier in regexes of the functionList.xml file, but you’re quite right : this improve readability of text and, surely, helps in achieving overall exact regexes :-))Cheers,

Great job. You’re a genius. Making the regex multiline and commentes is real blessing.
I’ve added several whitespaces \s where i missed them.
I’ve added bounded templates <T extends A & B>
I’ve added multiple inheritance - interface can extend multiple interfaces
I’ve generalized the DECLARATOR and GENERIC groups a bit.The result is far from perfect, but it completely satisfies my needs. I don’t mind if it recognizes multiple inheritance. We can leave some work for compiler too. I hope this class-function template will help with other languages.
