Provides methods for creating an array of class, method and
field names to be included as meta keywords in the HTML header
of class pages. These keywords improve search results
on browsers that look for keywords.
This is NOT part of any supported API.
If you write code that depends on this, you do so at your own risk.
This code and its internal interfaces are subject to change or

Returns an array of strings where each element

used to create one meta keyword tag for each element.
Method parameter lists are converted to "()" and
overloads are combined.
Constructors are not included because they have the same
name as the class, which is already included.
Nested class members are not included because their
definitions are on separate pages.
