在Eclipse中，如何更改类/类型模板中的默认修饰符？

Question

Eclipse's default template for new types (Window > Preferences > Code Style > Code Templates > New Java Files) looks like this:

${filecomment}
${package_declaration}

${typecomment}
${type_declaration}

Creating a new class, it'll look something like this:

package pkg;

import blah.blah;

public class FileName {
    // Class is accessible to everyone, and can be inherited 
}

Now, I'm fervent in my belief that access should be as restricted as possible, and inheritance should be forbidden unless explicitly permitted, so I'd like to change the ${type_declaration} to declare all classes as final rather than public :

package pkg;

import blah.blah;

final class FileName {
    // Class is only accessible in package, and can't be inherited
}

That seems easier said than done. The only thing I've found googling is a 2004 question on Eclipse's mailing list which was unanswered.

So, the question in short: How can I change the default class/type modifiers in Eclipse?

I'm using Eclipse Galileo (3.5) if that matters.

Answer 1

Looks like it is not possible. The ${type_declaration} is internal stuff.

What you can do is to click everytime the final checkbox in the "New Java Class"-Dialog. But that's not something you want to.

Answer 2

Just check the appropriate access modifier when creating the new class with the New Class Wizard.

Okay, i think there isn't any cool answer, so what about that "hack"?

${filecomment}
${package_declaration}

${typecomment}
import invalid;/* ${type_declaration} */

final class ${type_name} { }

If you now hit Control + Shift + O to organize imports, the old type declaration disappears. You could also add organize imports to save action to automate.

I know it's bad, but it does what you want.

Here is my workaround:

Edit the template:

${filecomment}
${package_declaration}

${typecomment}   
final class ${type_name} {

    /* ${type_declaration} //delete */

    /** 
     * @see {@link Object#toString()}
     * @return String representation of this instance. 
     */
    public String toString() {
        return "some impl";
    }

}

Comment out the ${type_declaration} because it is required. You have comment to delete, but requirement is achieved. Sorry if this is a 2 year old thread, but to me it is still relevant.
