Method Detail

values

public static PreBuiltTokenizers[] 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 (PreBuiltTokenizers c : PreBuiltTokenizers.values())
    System.out.println(c);

Returns:

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

valueOf

public static PreBuiltTokenizers 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

create

protected abstract org.apache.lucene.analysis.Tokenizer create(Version version)

getTokenizerFactory

public TokenizerFactory getTokenizerFactory(Version version)

getOrDefault

public static PreBuiltTokenizers getOrDefault(String name,
                                              PreBuiltTokenizers defaultTokenizer)

Get a pre built Tokenizer by its name or fallback to the default one

Parameters:

name - Tokenizer name

defaultTokenizer - default Tokenizer if name not found
