Method Detail

add

public TrieBuilder<T> add(java.lang.String word,
                          T value)

Add a word-value mapping to the Trie. Expects there not to be a previous mapping for the word.

Parameters:

word - The word for the word-value mapping.

value - The value for the word-value mapping.

Returns:

this, for chaining.

Throws:

java.lang.IllegalStateException - If this Trie already contained a mapping for the given word.

addAll

public TrieBuilder<T> addAll(java.util.Map<java.lang.String,T> map)

Add all word-value pairs from the given map to the Trie. Expects there not to be any previous mappings for any of the words.

Parameters:

map - Map to add word-value pairs from.

Returns:

this, for chaining.

Throws:

java.lang.IllegalStateException - If this Trie already contained a mapping for any of the map's words (keys).

set

public TrieBuilder<T> set(java.lang.String word,
                          T value)

Set a word-value mapping on the Trie. If a previous mapping exists, it will be overwritten. Otherwise, will create a new word-value mapping.

Parameters:

word - The word for the word-value mapping.

value - The value for the word-value mapping.

Returns:

this, for chaining.

setAll

public TrieBuilder<T> setAll(java.util.Map<java.lang.String,T> map)

Set all word-value pairs in the given map to the Trie. If any previous mapping exists, it will be overwritten.

Parameters:

map - Map to set word-value pairs from.

Returns:

this, for chaining.

build

public Trie<T> build()

Returns:

A Trie created from the word-value mappings in this TrieBuilder.
