I implemented final methods and final classes a little while back.
All of the following classes became final, which means that all of
their methods became aliases for functions rather than double-
dereference invocations via vtable:
DelDocs
PostingsWriter
SegInfo
TermInfo
TermInfosWriter
TermVectorsReader
TermVectorsWriter
InStream
OutStream
SortExternal
Truncated mean time to index 1000 Reuters news stories:
Before: 1.83 seconds
After: 1.82 seconds
Glad it didn't take me very long to implement. :)
Thanks for posting this. It'll probably save me a lot of time (or
worry) in the future. ;-)
