Index, a new generalization super root
--------------------------------------
Key: LUCENE-581
URL: http://issues.apache.org/jira/browse/LUCENE-581
Project: Lucene - Java
Type: New Feature
Components: Index
Versions: 2.0.0
Reporter: Karl Wettin
Priority: Minor
This update adds a new super class Index, extended by Directory. It allows for
transparent communication between your application and the persistency
mechanism. It takes issue 550 one step closer to backwards compability.
* Term and Document are no longer final classes.
* InterfaceIndexWriter
I also added these two in the Index.
abstract index.openIndexWriter()
abstract index.openIndexReader();
There is some bonus material that use this:
* Decorators for
* Index
* InterfaceIndexWriter
* IndexReader
* IndexSearcher
* NotifiableIndex, adds notification of changes to any Index.
* CreateListener
* DeleteListener
* OptimizationListener (not implemented)
* ContentUpdateListener, reacts to any change of the index. Optimized for
some implementations.
* AutofreshedSearcher, contains a searcher that is always up to date with the
index and have a buffer with old searchers that will be closed when nobody is
using them anymore (hopefully).
