Constructor Detail

TextTrieMap

public TextTrieMap(boolean ignoreCase)

Constructs a TextTrieMap object.

Parameters:

ignoreCase - true to use simple case insensitive match

Method Detail

put

public TextTrieMap<V> put(CharSequence text,
                          V val)

Adds the text key and its associated object in this object.

Parameters:

text - The text.

val - The value object associated with the text.

get

public Iterator<V> get(String text)

Gets an iterator of the objects associated with the longest prefix matching string key.

Parameters:

text - The text to be matched with prefixes.

Returns:

An iterator of the objects associated with the longest prefix matching matching key, or null if no matching entry is found.

get

public Iterator<V> get(CharSequence text,
                       int start)

Parameters:

text - The text to be matched with prefixes.

start - The start index of of the text

Returns:

An iterator of the objects associated with the longest prefix matching matching key, or null if no matching entry is found.
