Reynold Xin created SPARK-9518:
----------------------------------
Summary: Clean up GenerateUnsafeRowJoiner
Key: SPARK-9518
URL: https://issues.apache.org/jira/browse/SPARK-9518
Project: Spark
Issue Type: Sub-task
Components: SQL
Reporter: Reynold Xin
[~davies]'s suggestion on how to rewrite it to be more clear:
{code}
Seq.tabulate(outputBitsetWords) { i =>
val bitset = if (i< bitset1Words) {
getLong(obj1, i * 8)
} else if (i == bitset1Words && bitset1Remainder > 0) {
getLong(obj1, i* 8) | getLong(obj2, 0) >>> bitset1Remainder
} else {
getLong(obj2, i - bitset1Words) <<< bitset1Remainder | getLong(obj2 i -
bitset1Words + 1) >>> bitset1Remainder
}
putLong(buf, i * 8, bitset)
}
{code}
