Class CaptureTree

java.lang.Object

com.florianingerl.util.regex.CaptureTree

public class CaptureTree
extends Object

Contains all captures made during the previous match operation of all capturing groups in a hierarchical data structure.

E.g.

 Matcher matcher = Pattern.compile("(?x)" + "(?(DEFINE)" + "(?<sum> (?'summand')(?:\\+(?'summand'))+ )"
                + "(?<summand>  (?'product') | (?'number') )" + "(?<product> (?'factor')(?:\\*(?'factor'))+ )"
                + "(?<factor>(?'number') )" + "(?<number>\\d++)" + ")" + "(?'sum')").matcher("5+6*8");
 matcher.matches();
 System.out.println(matcher.captureTree());
 

prints out

 0
        sum
                summand
                        number
                summand
                        product
                                factor
                                        number
                                factor
                                        number
