Hello Developers,
I have been looking for a solid implementation of a Java BTree on disk
for the longest time. Could it be possible to use xindices btree on disk
seperately.
If so, where would be a good place to start. I have looked at the source
code, instantiated a new BTree and added values to it, but I got a null
pointer exception saying that the file was not opened.
I don't think you can use BTree class directly. Take a look at BTreeFiler - that
should be better fit. Once you instantiate it, you need to pass in configuration
and open it. Once you are done working with it, it needs to be closed.
See also org.apache.xindice.core.Collection, there you can see how to work with
Filers.
PS Have you seen JISP?
