Subject [jira] [Updated] (LUCENE-4877) Fix analyzer factories to throw exception when arguments are invalid
Date Mon, 01 Apr 2013 18:13:16 GMT

     [ https://issues.apache.org/jira/browse/LUCENE-4877?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Steve Rowe updated LUCENE-4877:
-------------------------------

    Attachment: LUCENE-4877-steve-minor-fixes.patch

Patch fixing these minor nits:

{quote}
TestMappingCharFilterFactory's factory could switch to being instantiated using the charFilterFactory()
method
EdgeNgramTokenizerFactory's gram size constants are pulled from EdgeNgramTokenFilter instead
of EdgeNgramTokenizer
LimitTokenCountFilterFactory's maxTokenCount param should be required; this is a pre-existing
problem though
PatternTokenizerFactory's group param should use the getInt() method with a default of -1.
{quote}

Actually, I was wrong about LimitTokenCountFilterFactory - it already has a test in place
to insure reporting of missing required maxTokenCount param.

Committing shortly.

> Currently if someone typos an argument "someParamater=xyz" instead of someParameter=xyz,
they get no exception and sometimes incorrect behavior.
> It would be way better if these factories threw exception on unknown params, e.g. they
removed the args they used and checked they were empty at the end.
