org.apache.lucene.analysis.ja.JapaneseTokenizer.Mode

All Implemented Interfaces:

Serializable, Comparable<JapaneseTokenizer.Mode>

Enclosing class:

JapaneseTokenizer

public static enum JapaneseTokenizer.Mode
extends Enum<JapaneseTokenizer.Mode>

Tokenization mode: this determines how the tokenizer handles compound and unknown words.

Enum Constant Summary

Enum Constants

Enum Constant	Description
EXTENDED	Extended mode outputs unigrams for unknown words.
NORMAL	Ordinary segmentation: no decomposition for compounds,
SEARCH	Segmentation geared towards search: this includes a decompounding process for long nouns, also including the full compound token as a synonym.

Method Summary

Modifier and Type	Method	Description
static JapaneseTokenizer.Mode	valueOf(String name)	Returns the enum constant of this type with the specified name.
static JapaneseTokenizer.Mode[]	values()	Returns an array containing the constants of this enum type, in the order they are declared.

Method Detail

values

public static JapaneseTokenizer.Mode[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (JapaneseTokenizer.Mode c : JapaneseTokenizer.Mode.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static JapaneseTokenizer.Mode valueOf(String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

IllegalArgumentException - if this enum type has no constant with the specified name

NullPointerException - if the argument is null
