Description

ArrayData is only some interfaces for getting data, such as: getBoolean, getByte.

When the element type of array is unknow, I want to judgment the element type first.

I have PR working in process:

https://github.com/beliefer/spark/commit/5787c6f062795aa7931c58ac2302ba607d3a97aa

The array function ArrayNDims is used to get the Dimension of array.

If ArrayData can support some interfaces like isBoolean, isByte, isArray, My job will be easier.
