NAME

       dnsjit.lib.trie.iter - Iterator of the trie.

SYNOPSIS

   Iterate over all trie's key-value pairs
         local trie = require("dnsjit.lib.trie").new("uint64_t")
         local iter = trie:iter()
         local node = iter:node()
         while node ~= nil do
             local key = node:key()
             local value = tonumber(node:get())
             print(key..": "..value)
             iter:next()
             node = iter:node()
         end

DESCRIPTION

       Beware that iterator is only valid as long as the trie's key-set remains unchanged.

   Functions
       TrieIter.new(trie)
              Create a new iterator pointing to the first element (if any).

       TrieIter:log()
              Return the Log object to control logging of this instance or module.

       TrieIter:node()
              Return  the  node  pointer  to by the iterator.  Returns nil when iterator has gone
              past the last element.

       TrieIter:next()
              Advance the iterator to the next element.

              Iteration is in ascending lexicographical order.  Empty string would be  considered
              as the very first.

              You  may  not  use this function if the trie's key-set has been modified during the
              lifetime of the iterator (modifying only values is OK).
