Karl Wettin updated LUCENE-580:
-------------------------------
Attachment: trunk.diff
An implementation suggestion. The project will not compile as there are two
Fieldable implementations that does not implement the tokenStreamFactoryValue()
method, LazyField and FieldForMerge. I suspect they could just return null
values, but I leave it open as I'm not sure.
Patch contains:
public interface TokenStreamFactory {
public abstract TokenStream factory() throws IOException;
}
/** Encapuslates a single instance of TokenStream that can be passed on ONCE. */
public class SimplePreAnalyzedField implements TokenStreamFactory {
/** Caches an instance of TokenStream in a List, reassembled to a TokenStream
for each call to factory() */
public class CachedPreAnalyzedField implements TokenStreamFactory {
> Pre-analyzed fields
