    // As these replacements are processed one at a time, if one is a prefix (or actually is just
    // contained in) another, it must be processed after that other one. To ensure that we can
    // process them in the correct order, they are inserted into allPaths in order of length
    // (longest first). Then, if they are processed in the order in allPaths, prefixes will be
    // handled correctly.

            (left, right) -> right.getKey().toString().length() - left.getKey().toString().length()));

    // is fine).//from   w  ww.  j  a  v a 2 s  .c o m
