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.
