Cool.

Here is a proposal for the javadoc. Could you also update the filter documentation page?

/**
 * This filter matches all elements that can be considered as line of code (e.g. directly contained in a block, or a then statement). This discards CtStatement that are not used as statement (such as a method call used as RHS).
 * <pre>
* // lines of a method
 * List<CtStatement> lines = method.getElement(new LineFilter());
 * </pre>
 */

I'm not sure that getElement(new LineFilter()) is more useful than getParent(...).
Personally, I nerver used getElements(new LineFilter()) but I almost use getParent(new LineFilter()) in all my projects.

getParent(new LineFilter())
for what purpose?

Done

for what purpose?

In order to

• insert element before/after the current line
• analyse the repetition of a element in the statement
• know the type of the parent line
• instrument the line that contains my current element
• ...

This filter can be useful if you have to count the number of line of a project (but not efficient).

// count the number of line of a project
ctRootPackage.getElements(new LineFilter()).size();

@GerardPaligot Why OverriddenMethodFilter is duplicated?
