Move & rename the terms dict, index, abstract postings out of
oal.index.codecs.standard
---------------------------------------------------------------------------------------
Key: LUCENE-2647
URL: https://issues.apache.org/jira/browse/LUCENE-2647
Project: Lucene - Java
Issue Type: Improvement
Components: Index
Affects Versions: 4.0
Reporter: Michael McCandless
Assignee: Michael McCandless
Priority: Minor
Fix For: 4.0
Attachments: LUCENE-2647.patch
The terms dict components that current live under Standard codec
(oal.index.codecs.standard.*) are in fact very generic, and in no way
particular to the Standard codec. Already we have many other codecs
(sep, fixed int block, var int block, pulsing, appending) that re-use
the terms dict writer/reader components.
So I'd like to move these out into oal.index.codecs, and rename them:
* StandardTermsDictWriter/Reader -> PrefixCodedTermsWriter/Reader
* StandardTermsIndexWriter/Reader -> AbstractTermsIndexWriter/Reader
* SimpleStandardTermsIndexWriter/Reader -> SimpleTermsIndexWriter/Reader
* StandardPostingsWriter/Reader -> AbstractPostingsWriter/Reader
* StandardPostingsWriterImpl/ReaderImple -> StandardPostingsWriter/Reader
With this move we have a nice reusable terms dict impl. The terms
index impl is still well-decoupled so eg we could [in theory] explore
a variable gap terms index.
Many codecs, I expect, don't need/want to implement their own terms
dict....
There are no code/index format changes here, besides the renaming &
fixing all imports/usages of the renamed class.
