Enclosing class:

ToHTMLStream

static class ToHTMLStream.Trie
extends java.lang.Object

Nested Class Summary

private static class

ToHTMLStream.Trie.Node The node representation for the trie.

Field Summary

static int	ALPHA_SIZE Size of the m_nextChar array.
private char[]	m_charBuffer helper buffer to convert Strings to char arrays
private boolean	m_lowerCaseOnly true if the search for an object is lower case only with the key
(package private) ToHTMLStream.Trie.Node	m_Root The root node of the tree.

Constructor Summary

ToHTMLStream.Trie()
Construct the trie that has a case insensitive search.

ToHTMLStream.Trie(boolean lowerCaseOnly)
Construct the trie given the desired case sensitivity with the key.

ToHTMLStream.Trie(ToHTMLStream.Trie existingTrie)
Construct the trie from another Trie.

Method Summary

java.lang.Object	get(java.lang.String key) Get an object that matches the key.
java.lang.Object	get2(java.lang.String key) Get an object that matches the key.
int	getLongestKeyLength() Get the length of the longest key used in the table.
java.lang.Object	put(java.lang.String key, java.lang.Object value) Put an object into the trie for lookup.

Size of the m_nextChar array.

Constant Field Values

m_Root

final ToHTMLStream.Trie.Node m_Root

The root node of the tree.

m_charBuffer

private char[] m_charBuffer

helper buffer to convert Strings to char arrays

m_lowerCaseOnly

private final boolean m_lowerCaseOnly

true if the search for an object is lower case only with the key

Constructor Detail

ToHTMLStream.Trie

public ToHTMLStream.Trie()

Construct the trie that has a case insensitive search.

ToHTMLStream.Trie

public ToHTMLStream.Trie(boolean lowerCaseOnly)

Construct the trie given the desired case sensitivity with the key.

Parameters:

lowerCaseOnly - true if the search keys are to be loser case only, not case insensitive.

ToHTMLStream.Trie

public ToHTMLStream.Trie(ToHTMLStream.Trie existingTrie)

Construct the trie from another Trie. Both the existing Trie and this new one share the same table for lookup, and it is assumed that the table is fully populated and not changing anymore.

Parameters:

existingTrie - the Trie that this one is a copy of.

Method Detail

put

public java.lang.Object put(java.lang.String key,
                            java.lang.Object value)

Put an object into the trie for lookup.

Parameters:

key - must be a 7-bit ASCII string

value - any java object.

Returns:

The old object that matched key, or null.

get

public java.lang.Object get(java.lang.String key)

Get an object that matches the key.

Parameters:

key - must be a 7-bit ASCII string

Returns:

The object that matches the key, or null.

get2

public java.lang.Object get2(java.lang.String key)

Get an object that matches the key. This method is faster than get(), but is not thread-safe.

Parameters:

key - must be a 7-bit ASCII string

Returns:

The object that matches the key, or null.

getLongestKeyLength

public int getLongestKeyLength()

Get the length of the longest key used in the table.
