Class PathMapper

  • public class PathMapper
extends Object
    The PathMapper is used to map file patterns to keys, and find an approriate key for a given file path. The pattern rules are consistent with those defined in the Servlet 2.3 API on the whole. Wildcard patterns are also supported, using any combination of * and ?.

    Example

    PathMapper pm = new PathMapper();

    pm.put("one","/");
    pm.put("two","/mydir/*");
    pm.put("three","*.xml");
    pm.put("four","/myexactfile.html");
    pm.put("five","/*\/admin/*.??ml");

    String result1 = pm.get("/mydir/myfile.xml"); // returns "two";
    String result2 = pm.get("/mydir/otherdir/admin/myfile.html"); // returns "five";
