Matching parentheses with a RowFilter (regexFilter)
java, jtable, regex, rowfilter, swing
Solution
Parentheses are meta-characters in regular expressions. Hence you are actually trying to match `John Smith` (without parentheses). What you need to do is to escape them.
Java has a built-in function to escape all meta-characters automatically: `Pattern.quote`. Run `s` through this function and it should fix it.
Also note that you might want to surround the pattern with `^...$`. Otherwise it would accept rows containing something like `This is John (Smith) foobar.` (because the regex is glad if it can match a substring of the input).
Problem
``` protected void searchFilter(String s, int n) { RowFilter<MyTableModel, Object> rf = null; try { System.out.println(s); rf = RowFilter.regexFilter(s, n); } catch (PatternSyntaxException e) { System.out.println(e); } filters.add(rf); } ``` I am trying to match a string in a JTable, that contains parentheses. In the above code, the string parameter could be: John (Smith) And the column i'm searching in: ``` Jane (Doe) John (Smith) John (Smith) Jack (Smith) ``` Where I want it to return: ``` John (Smith) John (Smith) ``` But right now it doesn't return anything. I have looked at the documentation for Matcher, Pattern and RowFilter, but nothing has helped me so far.
