Method Detail

parsePopList

public static void parsePopList(java.lang.String poplist,
                                java.util.List list)

Takes a String representing a poplog list and adds it as a linked list to the list provided. This works by recursively adding all the items of the string to a list, then if nested lists are found the method creates a new list, adds it, and calls itself upon the rest of the list, returning when the list closes. For example:

String s = [a long and winding [pop11 list [with nested stuff] just to check [that] it] works];
LinkedList ll = new LinkedList();
parsePopList(s, ll);
System.out.println(ll);

will print: [[a, long, and, winding, [pop11, list, [with, nested, stuff], just, to, check, [that], it], works]]
or:

String s = "long and winding [pop11 list [with nested stuff] just to check [that] it] works";
LinkedList ll = new LinkedList();
parsePopList(s, ll);
System.out.println(ll);

will print: [long, and, winding, [pop11, list, [with, nested, stuff], just, to, check, [that], it], works]

Parameters:

poplist - The list to convert

list - A linked list that will contain the items of the String
