> I would like to see payloads tested as well.
I'm new to payloads and don't know what makes sense when it comes to populating
the aprioi/test indices. Any preferences? Or should I just randomly add some
payloads to the positions of a couple of terms in a couple of documents?
> package level javadoc
Any comments on how to include graphics in the documentation? (I'm a big fan of
UML, you might have noticed there is quite a bit of ASCII class diagram stubs
in the javadocs of fields that represent binary associations, association
classes and qualifications.) Also, where should I store the XML used to render
the graphics? Just pop it all in the src classpath?
> I notice a TODO as well saying implement locking. Thoughts on implementing it?
It used to be a ReentrantLock, but for some reason I can't seem to recall, this
was a bad idea. There are TODO: lock and TODO: release lock tags left
throughout the code. I should probably take a look at o.a.l.store.Lock.
There are three more caveats I know of, but I'm not certain how important they
are to fix.
IndexReader:
public Document document(int n, FieldSelector fieldSelector) throws
IOException {
// todo: it does not make to much sense to use field selector using this
implementation,
// todo: so it simply ignores this and return everything.
return document(n);
}
public Collection getFieldNames(FieldOption fldOption) {
if (fldOption != FieldOption.ALL) {
throw new IllegalArgumentException("Only FieldOption.ALL implemented.");
// todo
}
IndexWriter.addDocument does not support readerValue and binaryValue.
if (field.isTokenized()) {
int termCounter = 0;
final TokenStream tokenStream;
// todo readerValue(), binaryValue()
if (field.tokenStreamValue() != null) {

> An non file centrinc all in memory index. Consumes some 2x the memory of a
> RAMDirectory (in a term satured index) but is between 3x-60x faster depending
> on application and how one counts. Average query is about 8x faster.
> IndexWriter and IndexModifier have been realized in InterfaceIndexWriter and
> InterfaceIndexModifier.
> InstantiatedIndex is wrapped in a new top layer index facade (class Index)
> that comes with factory methods for writers, readers and searchers for unison
> index handeling. There are decorators with notification handling that can be
> used for automatically syncronizing searchers on updates, et.c.
> Index also comes with FS/RAMDirectory implementation.
