Similar to definition of `def getValue(key: InternalRow): InternalRow` above. I added comment to say `Returns key index and matched single row.`, to be consistent with comment of `getValue`. Hope this is clear enough. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
