Assignee: Michael Busch
> All Tokenizer implementations should have constructors that take AttributeSource and AttributeFactory
> -----------------------------------------------------------------------------------------------------
>
> Key: LUCENE-1826
> URL: https://issues.apache.org/jira/browse/LUCENE-1826
> Project: Lucene - Java
> Issue Type: Improvement
> Components: Analysis
> Affects Versions: 2.9
> Reporter: Tim Smith
> Assignee: Michael Busch
> Fix For: 2.9
>
>
> I have a TokenStream implementation that joins together multiple sub TokenStreams (i then do additional filtering on top of this, so i can't just have the indexer do the merging)
> in 2.4, this worked fine.
> once one sub stream was exhausted, i just started using the next stream
> however, in 2.9, this is very difficult, and requires copying Term buffers for every token being aggregated
> however, if all the sub TokenStreams share the same AttributeSource, and my "concat" TokenStream shares the same AttributeSource, this goes back to being very simple (and very efficient)
> So for example, i would like to see the following constructor added to StandardTokenizer:
> {code}
> public StandardTokenizer(AttributeSource source, Reader input, boolean replaceInvalidAcronym) {
> super(source);
> ...
> }
> {code}
> would likewise want similar constructors added to all Tokenizer sub classes provided by lucene
