Searching for a method with a specific parameter count (in Eclipse)

Question

I want to use the Eclipse search to find all method calls for a method which takes a variable argument count, like this: public void myMethod(String s, Object o, String... categories) and get all which have specific counts of the optional parameter at the end.

So for example i would like to find all occurrences of myMethod("test", niceObject) when i want those without any optional parameters. I know atleast this part can be done via regex, but this will stop working as soon as someone has split it up into multiple lines (or my regex-fu isn't strong enough :) ).

Any suggestions appreciated, be it using the eclipse built-in search functionality or a good regex which can deal with multiline method calls-

Answer 1

(?s)foo\(([^,]+,){2}[^,]+\); matches calls to a method foo with 3 parameters.

Here are the details:

• (?s) is used for matching multiple lines
• [^,]+ matches everything but ,
• ([^,]+,){2} matches a list of 2 arguments; replace 2 with the number of arguments you want - 1
• [^,]+\); matches the last argument, followed here by );

Answer 2

Using the Eclipse File Search this one should work with multiline method calls (with 2 being the vararg count):

myMethod\([^,]+,[^,]+(,[^,]+){2}\)
