Subject [jira] Created: (LUCENE-2778) Allow easy extension of RAMDirectory
Date Thu, 25 Nov 2010 13:57:14 GMT
Allow easy extension of RAMDirectory
------------------------------------

                 Key: LUCENE-2778
                 URL: https://issues.apache.org/jira/browse/LUCENE-2778
             Project: Lucene - Java
          Issue Type: Improvement
          Components: Store
            Reporter: Shai Erera
            Assignee: Shai Erera
            Priority: Minor
             Fix For: 3.1, 4.0


RAMDirectory uses RAMFiles to store the data. RAMFile offers a newBuffer() method for extensions
to override and allocate buffers differently, from e.g. a pool or something. However, RAMDirectory
always allocates RAMFile and doesn't allow allocating a RAMFile extension, which makes RAMFile.newBuffer()
unusable.

I think we can simply introduce a newRAMFile() method on RAMDirectory and make the RAMFiles
map protected, and it will allow really extending RAMDir.

I will post a patch later.
