Method Detail

add	back to summary
public CharsTrieBuilder add(CharSequence s, int value) Adds a (string, value) pair. The string must be unique. The string contents will be copied; the builder does not keep a reference to the input CharSequence. Parameters s:CharSequence The input string. value:int The value associated with this char sequence. Returns:CharsTrieBuilder this ICU Status Stable since ICU 4.8.

add

back to summary

public CharsTrieBuilder add(CharSequence s, int value)

Adds a (string, value) pair. The string must be unique. The string contents will be copied; the builder does not keep a reference to the input CharSequence.

Parameters

s:CharSequence: The input string.
value:int: The value associated with this char sequence.

Returns:CharsTrieBuilder

this

ICU Status

Stable since ICU 4.8.

build	back to summary
public CharsTrie build(StringTrieBuilder.Option buildOption) Builds a CharsTrie for the add()ed data. Once built, no further data can be add()ed until clear() is called. A CharsTrie cannot be empty. At least one (string, value) pair must have been add()ed. Multiple calls to build() or buildCharSequence() return tries or sequences which share the builder's char array, without rebuilding. After clear() has been called, a new array will be used. Parameters buildOption:StringTrieBuilder.Option Build option, see StringTrieBuilder.Option. Returns:CharsTrie A new CharsTrie for the add()ed data. ICU Status Stable since ICU 4.8.

build

back to summary

public CharsTrie build(StringTrieBuilder.Option buildOption)

Builds a CharsTrie for the add()ed data. Once built, no further data can be add()ed until clear() is called.

A CharsTrie cannot be empty. At least one (string, value) pair must have been add()ed.

Multiple calls to build() or buildCharSequence() return tries or sequences which share the builder's char array, without rebuilding. After clear() has been called, a new array will be used.

Parameters

buildOption:StringTrieBuilder.Option: Build option, see StringTrieBuilder.Option.

Returns:CharsTrie

A new CharsTrie for the add()ed data.

ICU Status

Stable since ICU 4.8.

buildChars	back to summary
private void buildChars(StringTrieBuilder.Option buildOption)

buildCharSequence	back to summary
public CharSequence buildCharSequence(StringTrieBuilder.Option buildOption) Builds a CharsTrie for the add()ed data and char-serializes it. Once built, no further data can be add()ed until clear() is called. A CharsTrie cannot be empty. At least one (string, value) pair must have been add()ed. Multiple calls to build() or buildCharSequence() return tries or sequences which share the builder's char array, without rebuilding. After clear() has been called, a new array will be used. Parameters buildOption:StringTrieBuilder.Option Build option, see StringTrieBuilder.Option. Returns:CharSequence A CharSequence with the char-serialized CharsTrie for the add()ed data. ICU Status Stable since ICU 4.8.

buildCharSequence

back to summary

public CharSequence buildCharSequence(StringTrieBuilder.Option buildOption)

Builds a CharsTrie for the add()ed data and char-serializes it. Once built, no further data can be add()ed until clear() is called.

A CharsTrie cannot be empty. At least one (string, value) pair must have been add()ed.

Multiple calls to build() or buildCharSequence() return tries or sequences which share the builder's char array, without rebuilding. After clear() has been called, a new array will be used.

Parameters

buildOption:StringTrieBuilder.Option: Build option, see StringTrieBuilder.Option.

Returns:CharSequence

A CharSequence with the char-serialized CharsTrie for the add()ed data.

ICU Status

Stable since ICU 4.8.

clear	back to summary
public CharsTrieBuilder clear() Removes all (string, value) pairs. New data can then be add()ed and a new trie can be built. Returns:CharsTrieBuilder this ICU Status Stable since ICU 4.8.

clear
