org.apache.lucene.gdata.storage.lucenestorage.StorageBuffer

The StorageBuffer is used to buffer incoming updates, deletes and inserts to the storage. The storage uses an lucene index to store the enries. As modifying the index all the time an altering request comes in is not efficent. The entries will be added to the buffer to be available for incoming storage queries. If the loadfactor for the {@link org.apache.lucene.gdata.storage.lucenestorage.StorageModifier} isreached the modifier will perform a batch update on the index. Each entry will be associated with a feed id inside a associative datastructure to return a requested entry efficiently.

This implementation uses {@link java.util.concurrent.locks.ReadWriteLock}. The read lock may be held simultaneously by multiple reader threads, so long as there are no writers. The write lock is exclusive.

The entry and feed ID's must not be a composite key. The entry and feed ID must be unique.
