Shuai Zheng commented on SPARK-6994:
------------------------------------
I create one more pull request:
https://github.com/apache/spark/pull/5754
add few helper method to access field value by name also return type.
Basically create:
getBoolean(fieldName: String)
getByte(fieldName: String)
getShort(fieldName: String)
getInt(fieldName: String)
getLong(fieldName: String)
getFloat(fieldName: String)
getDouble(fieldName: String)
getString(fieldName: String)
getDecimal(fieldName: String)
This is a trial change, to make java developers life easier (like me...*_*), as
we won't benefit from generic feature on getAs[T]
> Allow to fetch field values by name in sql.Row
