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).
