There is a constructor in the RAMDirectory that already does that.

I don't think that worth modify the internal Lucene's code to achieve
a extra bit of performance...
What would you do on next version? Modify it agai
RAMDirectory has a constructor that takes in another Directory and
loads it into memory. No Serialization necessary. Just index to a
FSDirectory using Lucene's normal indexing methods (it takes care of
buffering them internally) and then load the FSDirectory into a
RAMDirectory. Have a l
You can serialize this object RAMDirectory em disk. When start the
application , it read the file .ser and load the object in memory.
The time of load of file .ser is much fast.
You need change any classes of Lucece: Add the "implements Serialzable" in
any classes.

provided enough RAM is available?
Not all index files are
