Class QueryStringFilter

java.lang.Object
  net.sf.gsaapi.util.QueryStringFilter

public class QueryStringFilter

extends java.lang.Object

This is a simple utility to manipulate url query strings. By specifying an array of url parameter names, this class allows you to use the filter method to strip out any other parameter names/values from an arbitrary query string.
String[] retainThese = new String[]{"param1", "param3"}; QueryStringFilter qsf = new QueryStringFilter(retainThese); System.out.println(qsf.filter("param1=value1¶m2=value2¶m3=value3¶m4=value4"));
The above code will print out: "param1=value1¶m3=value3"
In general, the order of the parameters is not guaranteed.
