No, it isn't. Think of the declaration as an entry in the table of
contents
in a book. It tells you which chapters exist and how to find them, but it
doesn't contain the actual chapter text. So you need to add the chapter
content somwehere to your book, just like you need to define the static
member variable somewhere, since otherwise, the TOC entry leads to
nowhere.
