 <method name> is the exact method's name. Note that constructors have dedicated patterns.
-<human-readable parametes> is a string representing parameters, which are not necessarily fully qualified. They do not affect the parser. For example, instead of (java.lang.Object, java.util.List, int) you are free to write just (Object, List<String>, int).
