Public Methods

Method Description
Create ( Lucene.Net.Util.AttributeSource factory, TextReader input ) : Tokenizer

Creates a TokenStream of the specified input using the given AttributeFactory
Create ( TextReader input ) : Tokenizer

Creates a TokenStream of the specified input using the default attribute factory.
ForName ( string name, string>.IDictionary args ) : TokenizerFactory

looks up a tokenizer by name from context classpath
LookupClass ( string name ) : Type

looks up a tokenizer class by name from context classpath
ReloadTokenizers ( ) : void

Reloads the factory list from the given ClassLoader. Changes to the factories are visible after the method ends, all iterators (#availableTokenizers(),...) stay consistent.

NOTE: Only new factories are added, existing ones are never removed or replaced.

This method is expensive and should only be called for discovery of new factories on the given classpath/classloader!

Protected Methods

Method Description
TokenizerFactory ( string>.IDictionary args ) : System

Initialize this factory via a set of key-value pairs.
