Subject [jira] [Commented] (LUCENE-4642) Add create(AttributeFactory) to TokenizerFactory and subclasses with ctors taking AttributeFactory, and remove Tokenizer's and subclasses' ctors taking AttributeSource
Date Thu, 14 Mar 2013 17:40:14 GMT

    [ https://issues.apache.org/jira/browse/LUCENE-4642?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13602482#comment-13602482
] 

Steve Rowe commented on LUCENE-4642:
------------------------------------

and in the base tokenizerfactory have
{code:java}
  /** just for ease of use... maybe @deprecated, maybe don't even have this method */
  public final Tokenizer create(Reader input) {
     return create(DEFAULT_ATTRIBUTE_FACTORY, input);
  }
{code}
{quote}

Okay, I understand, I'll make a patch - I plan on including the no-attr-factory create() variant,
and not deprecating it - I assume this will be used by most consumers.

> All tokenizer implementations have a constructor that takes a given AttributeSource as
parameter (LUCENE-1826).  These should be removed.
> TokenizerFactory does not provide an API to create tokenizers with a given AttributeFactory,
but quite a few tokenizers have constructors that take an AttributeFactory.  TokenizerFactory
should add a create(AttributeFactory) method, as should subclasses for tokenizers with AttributeFactory
accepting ctors.
