Detailed Description

The RefTrie itself

The trie support insertion and deletion of Key,Payload pairs, and lookup by Key (which can be an address or a subnet).

Additional methods are supported to provide access via iterators.

typedef RefTrieNode<A, Payload> Node

typedef RefTriePostOrderIterator<A, Payload> iterator

typedef RefTriePostOrderIterator<A, Payload> PostOrderIterator

void  set_root (Node *root)

set_root

iterator  insert (const Key & net, const Payload& p)

insert

insert a key, payload pair, returns an iterator to the newly inserted node. Prints a warning message if the new entry overwrites an existing full node.

void  erase (const Key &k)

erase

delete the node with the given key.

void  erase (iterator i)

erase

delete the node pointed by the iterator.

iterator  find (const Key &k)

find

[const]

given a key, returns an iterator to the entry with the longest matching prefix.

iterator  find (const A& a)

find

[const]

given an address, returns an iterator to the entry with the longest matching prefix.

iterator  lower_bound (const Key &k)

lower_bound

[const]

iterator  begin ()

begin

[const]

const iterator  end ()

end

[const]

void  delete_all_nodes ()

delete_all_nodes

iterator  lookup_node (const Key & k)

lookup_node

[const]

lookup a subnet, must return exact match if found, end() if not.

iterator  search_subtree (const Key &key)

search_subtree

[const]

returns an iterator to the subtree rooted at or below the key passed as parameter.

iterator  find_less_specific (const Key &key)

find_less_specific

[const]

find_less_specific asks the question: if I were to add this net to the trie, what would be its parent node? net may or may not already be in the trie. Implemented as a find() with a less specific key.

void  find_bounds (const A& a, A &lo, A &hi)

find_bounds

[const]

return the lower and higher address in the range that contains a and would map to the same route.

A  find_lower_bound (const A a)

find_lower_bound

[const]

A  find_higher_bound (const A a)

find_higher_bound

[const]

int  route_count ()

route_count

[const]

void  print ()

print

[const]
