Constructor Detail

RTrieNode

public RTrieNode()

Create an object of reversed trie node (default).

RTrieNode

public RTrieNode(char key,
                 int level)

Create an object of reversed trie node (default).

Parameters:

key - of current trie node

level - of the current node

RTrieNode

public RTrieNode(char key,
                 int level,
                 java.util.Vector<RTrieNode> child)

Create an object of reversed trie node (default).

Parameters:

key - of current trie node

level - of the current node

child - of the current node

Method Detail

SetChild

public void SetChild(java.util.Vector<RTrieNode> child)

Set the child of the current node. The child is a Vector of RTrieNode.

Parameters:

child - the child of the current node

GetChild

public java.util.Vector<RTrieNode> GetChild()

Get the child of the current node. The child is Vector of RTrieNode.

Returns:

the child of the current node

GetKey

public char GetKey()

Get the key of the current node. The key is a character form the matching pattern. Each node in a reverse trie tree is represented by a character from the pattern.

Returns:

the key character of the current node

GetLevel

public int GetLevel()

Get the level of the current node. The level of root is 0.

Returns:

the level of the current node

PrintNode

public void PrintNode()

Print out the detail information of a reverse trie node. This information includes key, level, and child.
