Method Details

getUpperSubNode

public IPv6AddressAssociativeTrie.IPv6AssociativeTrieNode<V> getUpperSubNode()

Description copied from class: AddressTrie.TrieNode

Returns the sub-node whose address is largest in value

Overrides:

getUpperSubNode in class AssociativeAddressTrie.AssociativeTrieNode<IPv6Address, V>

Returns:

getLowerSubNode

public IPv6AddressAssociativeTrie.IPv6AssociativeTrieNode<V> getLowerSubNode()

Description copied from class: AddressTrie.TrieNode

Returns the sub node whose address is smallest in value

Overrides:

getLowerSubNode in class AssociativeAddressTrie.AssociativeTrieNode<IPv6Address, V>

Returns:

getParent

public IPv6AddressAssociativeTrie.IPv6AssociativeTrieNode<V> getParent()

Description copied from class: AddressTrie.TrieNode

Returns the node for the subnet block containing this node.

Overrides:

getParent in class AssociativeAddressTrie.AssociativeTrieNode<IPv6Address, V>

Returns:

removeElementsContainedBy

public IPv6AddressAssociativeTrie.IPv6AssociativeTrieNode<V> removeElementsContainedBy(IPv6Address addr)

Description copied from interface: AddressTrieOps

Removes any single address or prefix block subnet from the trie that is contained in the given individual address or prefix block subnet.

Goes further than AddressTrieOps.remove(Address), not requiring a match to an inserted node, and also removing all the sub-nodes of any removed node or sub-node.

For example, after inserting 1.2.3.0 and 1.2.3.1, passing 1.2.3.0/31 to AddressTrieOps.removeElementsContainedBy(Address) will remove them both, while AddressTrieOps.remove(Address) will remove nothing. After inserting 1.2.3.0/31, then #remove(Address) will remove 1.2.3.0/31, but will leave 1.2.3.0 and 1.2.3.1 in the trie.

It cannot partially delete a node, such as deleting a single address from a prefix block represented by a node. It can only delete the whole node if the whole address or block represented by that node is contained in the given address or block.

If the given address is not a single address nor prefix block, then this method throws IllegalArgumentException.

If not a single address nor prefix block, the Partition class can be used to convert the address before calling this method. See AddressTrieOps.AddressTrieAddOps.add(Address) for more details.

Returns the root node of the subtrie that was removed from the trie, or null if nothing was removed.

Specified by:

removeElementsContainedBy in interface AddressTrieOps<V>

Overrides:

removeElementsContainedBy in class AssociativeAddressTrie.AssociativeTrieNode<IPv6Address, V>

Parameters:

addr -

Returns:

elementsContainedBy

public IPv6AddressAssociativeTrie.IPv6AssociativeTrieNode<V> elementsContainedBy(IPv6Address addr)

Description copied from interface: AddressTrieOps

Checks if a part of this trie is contained by the given prefix block subnet or individual address.

If the given address is not a single address nor prefix block, then this method throws IllegalArgumentException.

If not a single address nor prefix block, the Partition class can be used to convert the address before calling this method. See AddressTrieOps.AddressTrieAddOps.add(Address) for more details.

Returns the root node of the contained subtrie, or null if no subtrie is contained. The node returned need not be an "added" node, see BinaryTreeNode.isAdded() for more details on added nodes. The returned subtrie is backed by this trie, so changes in this trie are reflected in those nodes and vice-versa.

Specified by:

elementsContainedBy in interface AddressTrieOps<V>

Overrides:

elementsContainedBy in class AssociativeAddressTrie.AssociativeTrieNode<IPv6Address, V>

Parameters:

addr -

Returns:

elementsContaining

public IPv6AddressAssociativeTrie.IPv6AssociativeTrieNode<V> elementsContaining(IPv6Address addr)

Description copied from interface: AddressTrieOps

Finds the added subnets and/or addresses in the trie that contain the given individual address or prefix block subnet.

If the given address is not a single address nor prefix block, then this method throws IllegalArgumentException.

If not a single address nor prefix block, the Partition class can be used to convert the address before calling this method. See AddressTrieOps.AddressTrieAddOps.add(Address) for more details.

Returns a list of the nodes for prefix block subnets and addresses from the trie that contain the address or block. The list consists only of added nodes, see BinaryTreeNode.isAdded() for more details on added nodes. The list is constructed as a trie in which each parent node has only one sub-node.

Use AddressTrieOps.elementContains(Address) to check for the existence of a containing address.

Specified by:

elementsContaining in interface AddressTrieOps<V>

Overrides:

elementsContaining in class AssociativeAddressTrie.AssociativeTrieNode<IPv6Address, V>

Parameters:

addr -

Returns:

longestPrefixMatchNode

public IPv6AddressAssociativeTrie.IPv6AssociativeTrieNode<V> longestPrefixMatchNode(IPv6Address addr)

Description copied from interface: AddressTrieOps

Finds the containing subnet or address in the trie with the smallest subnet size, which is equivalent to finding the subnet or address with the longest matching prefix. Returns the node corresponding to that subnet.

If the given address is not a single address nor prefix block, then this method throws IllegalArgumentException.

If not a single address nor prefix block, the Partition class can be used to convert the address before calling this method. See AddressTrieOps.AddressTrieAddOps.add(Address) for more details.

Returns null if no added subnet or address contains the given argument.

Use AddressTrieOps.elementContains(Address) to check for the existence of a containing address.
To get all the containing addresses, use AddressTrieOps.elementsContaining(Address).
Use AddressTrieOps.longestPrefixMatch(Address) to get the address corresponding to the result of this method.

public Iterator<IPv6AddressAssociativeTrie.IPv6AssociativeTrieNode<V>> containingFirstIterator(boolean forwardSubNodeOrder)

Description copied from interface: TreeOps

Returns an iterator that does a pre-order binary tree traversal of the added nodes. All added nodes will be visited before their added sub-nodes. For an address trie this means added containing subnet blocks will be visited before their added contained addresses and subnet blocks.

This iterator supports the Iterator.remove() operation.

See the docs for TreeOps for more details on the ordering.

Specified by:

containingFirstIterator in interface AddressTrieOps<V>

Specified by:

containingFirstIterator in interface TreeOps<V>

Overrides:

containingFirstIterator in class AssociativeAddressTrie.AssociativeTrieNode<IPv6Address, V>

Parameters:

forwardSubNodeOrder - if true, a left sub-node will be visited before the right sub-node of the same parent node.

Returns:

containingFirstAllNodeIterator

public <C>
BinaryTreeNode.CachingIterator<IPv6AddressAssociativeTrie.IPv6AssociativeTrieNode<V>, IPv6Address, C> containingFirstAllNodeIterator(boolean forwardSubNodeOrder)

Description copied from interface: TreeOps

Returns an iterator that does a pre-order binary tree traversal. All nodes will be visited before their sub-nodes. For an address trie this means containing subnet blocks will be visited before their contained addresses and subnet blocks.

This iterator supports the Iterator.remove() operation.

Once a given node is visited, the iterator allows you to cache an object corresponding to the lower or upper sub-node that can be retrieved when you later visit that sub-node. That allows you to provide iteration context from a parent to its sub-nodes when iterating. The caching and retrieval is done in constant-time and linear space (proportional to tree size).

Here is an example showing usage of the caching. Consider this recursive code doing a pre-order traversal:

IPv6AddressTrie ipv6Tree = ...;
visitRecursive(ipv6Tree.getRoot(), null);

static <E> void visitRecursive(BinaryTreeNode<E> node, String direction) {
        if(direction == null) {
                direction = "root";
        }
        System.out.println("visited " + direction + " " + node);
        BinaryTreeNode<E> sub = node.getLowerSubNode();
        if(sub != null) {
                visitRecursive(sub, direction + " left");
        }
        sub = node.getUpperSubNode();
        if(sub != null) {
                visitRecursive(sub, direction + " right");
        }
}

The following iterative code provides the same functionality:

visitIterative(ipv6Tree.getRoot());

static <E> void visitIterative(BinaryTreeNode<E> node) {        
        CachingIterator<? extends BinaryTreeNode<E>, E, String>iterator = node.containingFirstAllNodeIterator(true);
        while(iterator.hasNext()) {
                BinaryTreeNode<E> next = iterator.next();
                String direction = iterator.getCached();
                if(direction == null) {
                        direction = "root";
                }
                System.out.println("visited " + direction + " " + next);
                iterator.cacheWithLowerSubNode(direction + " left");
                iterator.cacheWithUpperSubNode(direction + " right");
        }
}

public IPv6AddressAssociativeTrie<V> asNewTrie()

Description copied from class: AddressTrie.TrieNode

Creates a new sub-trie, copying the nodes starting with this node as root. The nodes are copies of the nodes in this sub-trie, but their keys and values are not copies.

Overrides:

asNewTrie in class AssociativeAddressTrie.AssociativeTrieNode<IPv6Address, V>

cloneTree

public IPv6AddressAssociativeTrie.IPv6AssociativeTrieNode<V> cloneTree()

Description copied from class: AssociativeAddressTrie.AssociativeTrieNode

Clones the subtrie starting with this node as root. The nodes are cloned, the keys and values are not cloned.

Overrides:

cloneTree in class AssociativeAddressTrie.AssociativeTrieNode<IPv6Address, V>

clone

public IPv6AddressAssociativeTrie.IPv6AssociativeTrieNode<V> clone()

Description copied from class: AssociativeAddressTrie.AssociativeTrieNode

Clones the node. Keys and values are not cloned, but parent node, lower and upper sub-nodes, are all set to null.

Overrides:

clone in class AssociativeAddressTrie.AssociativeTrieNode<IPv6Address, V>

equals

public boolean equals(Object o)

Description copied from class: AssociativeAddressTrie.AssociativeTrieNode

Returns whether the key and mapped value match those of the given node

Specified by:

equals in interface Map.Entry<IPv6Address, V>

Overrides:
