Uwe Schindler updated LUCENE-1842:
----------------------------------

    Fix Version/s:     (was: 2.9)

> Add reset(AttributeSource) method to AttributeSource
> ----------------------------------------------------
>
>                 Key: LUCENE-1842
>                 URL: https://issues.apache.org/jira/browse/LUCENE-1842
>             Project: Lucene - Java
>          Issue Type: Wish
>          Components: Analysis
>            Reporter: Tim Smith
>            Priority: Minor
>
> Originally proposed in LUCENE-1826
> Proposing the addition of the following method to AttributeSource
> {code}
> public void reset(AttributeSource input) {
>     if (input == null) {
>       throw new IllegalArgumentException("input AttributeSource must not be null");
>     }
>     this.attributes = input.attributes;
>     this.attributeImpls = input.attributeImpls;
>     this.factory = input.factory;
> }
> {code}
> Impacts:
> * requires all TokenStreams/TokenFIlters/etc to call addAttribute() in their reset() method, not in their constructor
> * requires making AttributeSource.attributes and AttributeSource.attributesImpl non-final
> Advantages:
> Allows creating only a single actual AttributeSource per thread that can then be used for indexing with a multitude of TokenStream/Tokenizer combinations (allowing utmost reuse of TokenStream/Tokenizer instances)
> this results in only a single "attributes"/"attributesImpl" map being required per thread
> addAttribute() calls will almost always return right away (will only be "initialized" once per thread)
